Contina IIa

Zeiss Ikon's Contina camera was a long lived and varied series of cameras.  The series started as the Ikonta 35 which was a post-war version of the 120 format Ikonta adapted to take 35 mm film.  This camera became two series of cameras - the Contessa and the Contina; the first Contessas and Continas were folding cameras. The Contessa version was more up-market than the Contina version. I have already written about one of the Contessa line - the Contessa LKE. The Contessa line have better lenses (Tessars) and coupled light meters and rangefinders. The Contina range have cheaper lenses (Novar, Novicar and Pantar) and the light meters, where present, are uncoupled. I have also written about the Contina line elsewhere - the Contina Ic.

lens: Novicar
focal length:  45mm
apertures: f2.8 to f22
focus range: 1m to infinity
lens fitting: fixed
shutter: Prontor-SVS
speeds: 1 second to 1/300 seconds
flash: PC connector
film size: 35mm

Contina IIa - front view, meter window closed
To make identifying and placing Contina cameras as difficult as possible, the Contina series split into two lines of cameras simultaneously.  The original Contina folding camera  became the Contina II folding camera with a light meter and then a series of derivatives. That original Contina folding camera, at the same time, became the Contina I rigid camera - no light meter or rangefinder - and then a series of derivatives.
Front view - meter window open

So, at any one time after 1953 there were two different Continas available, both just designated Contina. I have been referring to Contina I, Contina II, Contina Ic, Contina IIa but I don't think those were names offered by Zeiss Ikon, rather us collectors use them to make sense of the mish-mash of models.

Daniel Jiménez has produced a 'family tree' of the Contina series which he has given me permission to use here:

Daniel has a useful camera blog which can be found in an English version here. He also has a much larger Spanish version here.

This camera - is a Contina IIa. It is derived from the Contina II which was a folding camera but this version does not fold - that is, it is rigid. It is a compact and solid camera measuring 120 x 65 x 85 mm and weighs 567g. It offers a built-in but uncoupled light meter and an EV enabled shutter. It was not a cheap camera - it cost £43/15/1 in 1957 (in old money, or £43.76 in new money) which, given the average male wage in 1957 was £9.00 means this camera cost the equivalent of £2,500 in 2013 values. The version with a Novar lens only cost £36/12/7.

The top plate of the camera has a number of  items on it. On the left is a small rewind knob. I prefer these to the small folding cranks that became ubiquitous in the 1960s. When you first turn the rewind knob, it raises itself by one cm. This is above the height of the centre of the top plate and makes it easier to hold and turn.

rear and top view
Next to the rewind knob is an accessory shoe. At the time that this camera was made (1956/58) this was more likely to be used for a separate rangefinder than a flashgun. There are no electrical contacts in the accessory shoe so it is a cold shoe.

Next to the accessory shoe is the light meter window and the light meter control knob. Visible in the window is a needle connected to the light meter. The brighter the light, the more this needle moves towards the rear of the camera. Also in this window is a white circle which moves in response to the user moving the control knob. When the white circle is over the needle, the correct exposure can be read off the scale around the control knob. This is mostly in EV values - more later. In the centre of the control knob is the setting for the film speed. This camera was made in 1956/8 and uses the film speed standards in place at that time. A few years later (1960), the American Standards Association (ASA) revisited their film speed standard to produce the later ASA standard now known as ISO. The German DIN system remained unchanged so on this camera 21 DIN = 40 ASA rather than the later standard of 21 DIN = 100 ASA (ISO) - I always use the DIN standard with old cameras to make sure I do not get it wrong.

On the far right of the top plate is the film advance lever. This moves through about 200 degrees to advance the film and cock the shutter. The lever is all metal and only curves a very slight amount which I find makes it uncomfortable to use. In the centre of the film advance lever should be the frame counter. I can make no comment about this as a prior owner has removed it. Looking at the state of the metal that is left, I suspect a very amateurish attempt at a repair.

The front of the camera has four items - meter window, viewfinder window, shutter housing and flash PC connector. The meter window contains a two cm by one cm lens covering a selenium photoelectric cell.  This does not need any batteries, which I always reckon to be a good thing.  Most camera electrics from the 1960s to 1980s use mercury cells which are now illegal in just about every country there is. This window has a hinged cover - to open it, you lightly press the right-hand end (as the camera is to your eye). Selenium meters get a poor press as the photoelectric cell will deteriorate with time. However, if the cell is kept in the dark it only deteriorates very slowly, so this cell being covered, it has not yet (in 57 years) deteriorated enough to worry about. This is a single scale meter - an earlier version of the Contina IIa had a dual scale meter with a small window in the hinged cover.

Next to the meter window is the viewfinder window. This has quite a small eyepiece and a plain view with no bright lines. I find I cannot use it while wearing my glasses.  The Contina Ic, which I also own, has a much larger eyepiece - this was made just a few years later in the early 1960s.

In the centre of the front is a square chrome bezel containing the shutter.  This is a Prontor-SVS from Gauthier. This works on the EV system.  The light meter gives you an EV value from between  three and eighteen and you transfer this number to the shutter - you have to press a small tab on the shutter housing to get the EV ring to turn. Each EV number gives you a small range of shutter speed and aperture settings.  If you turn the EV setting ring without pressing the small tab, different speed/aperture combinations will present themselves to the mark at the top of the housing. For very low light levels, the shutter speeds are in green - you cannot set these, but you can read them.  To use them, turn the control ring on the shutter housing to B and read off a speed next to the aperture you want to use.  You then need to time the exposure yourself - the speeds are from four seconds to sixty seconds and you can count this quite accurately without a watch.

The lens is a Novicar lens (a Novar lens was also available) which I have found to be excellent if stopped down to f5.6 or f8. It is threaded for 27mm filters.  Maximum aperture is f2.8 and its focal length is 45 mm. Focusing is from about three feet to infinity (one metre to infinity). The throw of the focusing is only about 120 degrees, so very accurate focusing is not possible, but with no rangefinder, this camera was always going to rely on depth of field.

On the lower right of the shutter bezel (looking at the camera) is the flash PC (Prontor-Compur) connector.  This is the only means of connecting a flashgun. On the side of the shutter housing there is a selector for M or X - Magnesium or Xenon  - flash. M is for flash bulbs and X for electronic flash. With M, the flash is fired slightly before the shutter opens to allow the burning of the flash bulb to reach its maximum while the shutter is fully open. With X, the flash is fired as the shutter blades are fully open as electronic flash does not require time to reach its maximum intensity. This selector also has a V setting. This means Vorlaufwerk and is German for self timer. Moving the selector to this position causes an eight second delay between pressing the shutter release and the shutter firing. It is never a good idea to try this facility on an old camera as it might well cause the shutter to stop working permanently.

Rear/internal view

The back opens by pulling down a small catch on the lower right-hand edge. The back is hinged and there is a single light seal - a piece of velvet right by the hinge. The back itself has the pressure plate and a tensioning roller that goes by the take-up spool. Around the film mask are two machined film guides - showing as bright lines in the photograph above. The pawl for the rewind mechanism can be raised to enable fitting a film cassette and then lowered to secure the cassette.

I have now finished my test roll of film - Agfa Vista+ 200 ISO from Poundland (yes, £1.00 per roll!). As expected, the camera works well. The only awkward thing was setting the EV values on the shutter as the mechanism is rather stiff.  I definitely would not want it too loose but it would be nice for it to be a bit easier to alter. The frame counter is missing on this camera - I assume due to a botched repair by the previous owner. It does not affect the camera's functionality at all and got me the camera at a bargain price. Below are a selection of pictures from the test film.

Ihagee Exakta Varex IIb

This is one of Ihagee's 'serious' cameras.  It is very similar to the two Exas I already own but has more facilities and is built to a higher standard.  It is the usual Exakta/Exa rhomboidal shape.  On my two Exa cameras, the back and base come away as one to allow film loading.  The Varex IIb is more traditional with a hinged back.  This back, however, is also removable if you want.

lens: none
focal length:  n/a
apertures: n/a
focus range: n/a
lens fitting: Exakta double bayonet
shutter: horizontal cloth focal plane
speeds: 12 seconds to 1/1000 seconds
flash: three PC connectors, no accessory shoe
film size:  35mm
Exakta Varex IIb with lens and viewfinder added


The camera is heavy, weighing 581g without lens or viewfinder.  It is left-handed.  The film advance is on the left as is the shutter release and one of the two (yes, two) shutter speed selectors.

This camera came without a lens and has both (yes, both) the Exakta bayonet mounts so this camera will take any Exakta fit lens.  Strictly, this is a Varex IIa type bayonet as it has slots at the inner bayonet flanges (not sure why).
Exakta Varex IIb as I bought it

The reason for having two bayonet mounts on one camera is that the original mount restricted the width of attached lenses.  When Ihagee developed telephoto lenses, there was too much vignetting of the image to be usable. The new bayonet mount has a wider diameter and so allows wider lenses to be fitted.  (note: I am using the word 'wider' in a mechanical sense, not in its other, optical, sense.)

The shutter release is beside the lens mount to allow the use of automatic lenses.  In the Exakta system, the lens has a secondary shutter release which fits over the camera's shutter release.  When you press the lens' secondary release, the lens diaphragm closes and the primary release is pressed, actuating the shutter.

The shutter is a horizontal cloth focal plane shutter.  On this particular specimen, the shutter is faulty.  The mechanism sounds dry (there is a faint but clear squeal when the shutter actuates), the second curtain is significantly wrinkled and, at the slower speeds, the second curtain doesn't quite close.  At 1/1000, it works fine.

This is the only camera I have seen that has two speed selectors.  On the left is a small conventional selector that covers speeds from 1/30 to 1/1000 plus B and T.  This works in a fairly conventional manner - lift, turn to the required speed and release.


slow speed selector
fast speed selector
On the right of the camera is another speed selector which covers speeds from 1/8 to 12 seconds.  These figures are in black.  This selector also provides a delay of up to six seconds (using the figures in red).  When using the delay, you also get mirror lock up so reduced vibration can be achieved when using the macro attachment - a facility that no other of my SLRs has until my Canon EOS of 1995.  In the centre of the slow speed selector there is a film speed reminder dial.  As this camera is totally manual, this dial does nothing except remind you what film you have loaded into the camera.

Another quirky thing about Exakta cameras is the film advance lever.  This moves through over 300 degrees which is more than you can do in one motion.  I am actually finding this ok but I start the motion with my left thumb for the first half of the travel and then my left index finger takes over.  Around the film advance lever there is a frame counter.  This counts up from zero - so tells you how many frames you have shot.  It is also quirky as the frame count changes when you press the shutter release rather than when you advance the film.


Exakta cameras have exchangeable viewfinders.  When I bought this camera, there was no viewfinder with it, just a rectangular hole in the top plate.  I have two viewfinders for my Exa cameras and these fit this camera so I have a choice of an eye-level finder and a waist level finder.

Hole in the top plate for fitting the viewfinder
Moving to the front of the camera, there is little to note.  As I have mentioned, there is a double bayonet mount and a shutter release.  There are also three (yes, three) PC connectors for a flash gun.  Ihagee seem to have tried to be as idiosyncratic as possible with their cameras.  Rather than go down the route used by Prontor and Compur (hence PC) and have a switch to select between bulb and electronic flash, Ihagee have provided separate connectors , one for electronic flash and two for flash bulbs.

In fact, the three PC connectors can be used in various ways to allow different shutter speeds.  Using the X connector and a shutter speed of 1/60 allows use of electronic flash.  Using the FP (Focal Plane) connector allows shutter speeds up to 1/1000 seconds which is an incredibly fast shutter speed for flash.  The manual gives guide numbers for different bulbs and shutter speeds - the fast speeds being achieved because the flashbulbs suitable for the FP connector have a flash duration of around 1/40 second and so are burning throughout the expossure.  The F (Fast) connector allows small fast flashbulbs to be used with a shutter speed of 1/30.  The X (Electronic) connector can also be used with a shutter speed of 1/8 with any flashbulb.  I am not sure how much advantage is given to the photographer with the above choices, but I almost never use flash and have never used flashbulbs, so I am likely to be missing the point.

Underneath the camera are four knobs.  The smallest of these unscrews to allow the use of an internal knife to cut the film when an empty cassette is used in place of the take-up spool.  Next to this is the rewind knob with a small folding crank.  At the other end of the camera is a knob which is pulled away from the camera to release the catch on the back.  Between these two knobs is the tripod boss which is the standard 1/4 Whitworth tread.
Base of camera

The outside of the back has two small chrome rectangles and one large chrome rectangle.  These are the fitting for internal components, the small rectangles help to keep the film flat and the large rectangle is part of the fitting of the pressure plate.


Rear of camera

The camera in use:

I am trying out this camera (despite having a faulty shutter) with a roll of out-of-date and no longer made film - Kodak Plus X.  I have never used this film before but it had a very good reputation.  This film is monochrome and is rated at 125 ASA/22 DIN.  I don't know why but it seemed appropriate to try this camera with a vintage monochrome film.

The camera set-up I am using is the Varex IIb body, Carl Zeiss Jena Tessar (50mm and f2.8) and a waist-level viewfinder with a plain focussing screen.  [This lens should not be confused with a Carl Zeiss Opton Tessar from West Germany.  The Carl Zeiss Jena lens is the real thing.]

There are many options available for this camera for both lens and finder.  I have the Carl Zeiss Jena Tessar and two Meyer-Optik Domiplan lenses available and the waist-level finder and a pentaprism eye-level finder.  I am enjoying the waist-level finder but must admit to struggling a bit with the reverse action when I move the camera.

First aspect of the waist-level finder is the fact that the image is reversed left-to-right.  If you want to move the image to the right, you need to move the camera to the left.

It is also easy to get verticals at an angle.  Again, you have to move the camera the 'wrong' way to correct this.

This finder has a plain focussing screen which makes focussing a bit harder.  For me, this is not a significant problem as I usually use hyperfocal focussing.  On the rare occasions when I rely on critical focussing, there is a hinged magnifier available which is more than I shall ever need.  If not, other focussing screens are available with micro-prisms and split-image centres.

I have been carrying this camera around for about an hour this afternoon and I can confirm that this is a heavy camera.  There are strap lugs with split rings available to connect a strap.  A nice touch is the presence of triangular leather patches behind the split rings to stop the rings and strap ends from scratching the camera body.  While I have a number of straps available, I have not fitted one to this camera.

Contrary to my usual practice, I am using a shutter-priority exposure system, adjusting the aperture to vary the exposure.  The reason I am doing this is because this ('faulty') shutter seems to perform best at 1/125 seconds so I am keeping it set at this speed.

What I am finding, which delights me, is that I am seeing the image in the wauist-level finder as a picture rather than as a view.  This is making composition not so much easier (see my comments about image reversal) but clearer and more precise.  So far I much prefer it.

I am also finding the left-hand operation surprisingly easy.  I am no longer pressing the slow speed selector hoping to fire the shutter.  The film advance with its 300 degree travel is also surprisingly easy to use left handed.

As I have already said, I usually use hyperfocal focussing but if I did not I think I would find right-handed focussing cumbersome.

My first film being completed, I need to develop the film and scan it.  Then I shall post some sample pictures here.

Film is now developed and scanned.  Here are some example pictures, clearly showing the problem with the shutter is one of them.  The rest are not too bad (if you ignore my poor scanning ability!).

Voigtlander Vito I




Voigtlander Vito
I have used as a title for this article 'Vito I' but the camera is actually the Vito - Voigtlander were not aware of the forthcoming Vito range at this point.  I already have an article on the Vito II here and much in that article applies here as well.  The two cameras are very similar as you might expect.  The lens serial number says the lens was made in 1945 which is also the probable date of manufacture - one of the first cameras to be made in war-ravished Germany.

lens: Skopar
focal length: 50mm
apertures: 3.5 to 16
focus range: 1 metre to infinity
lens fitting: fixed
shutter: Prontor II
speeds:  1/5 to 1/200
flash: synchronised for bulbs
film size:  35mm

The camera is a folder and nicely compact when closed.  It measures 120mm by 70mm by 40mm closed and 120mm by 70mm by 80mm when open.  Closed, it nicely fits in a trouser or jacket pocket.  The only distinguishing mark on the closed camera is an ornate 'V' on the lens door and a fairly indistinct 'Voigtlander' is embossed on the leatherette on the back together with the model name 'Vito'.  There is also the country of origin embossed on the back which is 'Germany'.  As Germany is the English name for the country this indicates that it is an official import.  Strangely, for an official import, the focussing scale is in metres rather than feet, suggesting that Voigtlander were not fully geared up for export in 1945.
Vito top view

The top plate is very uncluttered.  There is a knurled ring at either end.  The right-hand ring is the film advance and the left-hand ring the rewind.  In the centre of the top plate is a very small, reverse Galilean viewfinder.  The eyepiece is only 5mm by 2.5mm.  The image seen is roughly 0.5 times life size.  This is very small compared to more modern viewfinders but it is more than adequate.  There is also a frame counter which counts up from one.  There is no accessory shoe (flash shoe) although one was available as an extra and fitted over the viewfinder.

On the rear of the top plate is a lever.  In the normal position (down) the film advance will only advance one frame.  When raised, the film can be advanced as far as you want and can be rewound.  The toothed wheel which is exposed by raising the this lever can be used to set the frame number to one.

The underside of the camera contains three items.  Close to the centre is a 3/8 Whitworth tripod boss.  A 1/4 Whitworth insert would have been available for the more usual tripod size.  There is also a button to release the lens door.  This is spring loaded and partially opens the door.  This door never sprung open under its own steam and from new they needed the user to fully open the door once it was released.

The third item on the base is two 'feet'.  These are little more than pins.  A third foot is on the lens door giving three feet altogether which allow the camera to sit stably on a flat surface.  This is primarily intended to allow group portraits using the self-timer.

When the door is opened, the lens comes forward on its bellows and locks in place.  The shutter release is on the top edge of the door together with a threaded socket for a standard cable release.
Vito - lens door open

The lens is a Skopar f3.5, 50mm lens.  This is the original version of the famous Color-Skopar and is not calculated for colour film.  However, it is intended for panchromatic film so should perform well with colour film.  See the test pictures below for details.  This lens focusses from one metre to infinity and has Voigtlander's usual two Happy Snapper settings - a circle for the hyperfocal distance at f5.6 (approximately five metres to infinity at f5.6 or 2.5 metres to infinity at f16) and a triangle which gives a focus range of 2.5 metres to five metres at f5.6 (ideal for groups).  This lens has no blue/purple tinge and so cannot have been coated as was normal post-WWII and so will be liable to flare.

The shutter is a Prontor II (which is the same as a Klio on a Zeiss Ikon camera) which is a pre-war design and was soon to be updated to the Prontor S.  This Prontor II has a PC connector and so must be synchronised for flash - I would suspect for fast flash bulbs (F: sync) but there is no indication of this on the shutter housing (my Vito II has a Pronto shutter and this is specifically marked F:).  Shutter speeds are 1/5, 1/10, 1/25, 1/50, 1/100 and 1/200 which is more than adequate.  The bezel of the shutter housing bears the shutter name - Prontor II - Gauthier's maker logo and Voigtlander's script name.
Vito - lens and shutter

There is a self-timer lever which we are always told not to use on old cameras to prevent damage to the shutter.  It barely works on this camera, taking 16 seconds to actuate the shutter and then needing a little help from my finger over the last two or three seconds.

This shutter needs cocking before use - the cocking lever moves from left to right and up to cock the shutter.

Apertures available are f3.5 to f16.  As there are no click-stops, you can set an intermediate value if you want to.  The only other item of note on the shutter assembly is a stellate lever.  I am not entirely sure what this is for but I suspect it was to do with the hinged yellow filter that the early Vitos were fitted with.  The shutter bezel has three screws in it that are also part of the filter assembly.  When production had used up the store of pre-war parts, the bezel no longer had these three screws.

Inside is where this camera gets interesting.  The design dates from 1939 and the camera was intended to use unperforated 35mm film.  As the film was unperforated, there are no sprockets in the camera.  Instead, the camera judges the film framing with a feeler roller as in an up-market 120 camera. I have been led to believe  by the Interweb that this camera was designed to use Kodak's 828 film which is unperforated 35 mm film with backing paper like 120 film. As the film came on a spool with backing paper (again, as with 120 film) there are springs fitted to the film chambers to keep the film tight on the spools. Actually, looking at the camera, there is no reason why the camera should not have used unperforated 35 mm film in a reloadable cassette - Leica and Zeiss Ikon made such cassettes for their 35 mm cameras. I have never seen a 1939 Vito - this would tells us immediately whether the camera used 828 film or a loadable cassette as 828 film would require a red window on the back of the camera to allow the user to see at least the first frame number. There is no red window on my 1945 Vito - was there one on the 1939 version? When production restarted in 1945, Voigtlander decided to modify the camera for modern perforated 35mm film (135 format).  The only real change is that the film gate (the rectangular opening that lets the light hit the film in the correct place) is reduced to 24mm by 36mm (originally it had been 30mm by 40mm).

The film take up chamber will take the standard spool from a 35mm cassette as a take-up spool or an empty cassette can be fitted which means that when the film is finished you can open the back and cut the film with the exposed part already in a cassette.

These pictures were taken with this camera on Agfa Vista plus 200 ISO colour negative film (details here): (the black wedge would seem to be a scanning artifact.  The frames all overlap about 1-2 mm and this overlap is also wedge shaped)

Yamato Pal Jr


Yamato Pal Jr




lens: Yamanon
focal length: 45 mm
apertures:  f2.8 to f16
focus range:3 feet to infinity
lens fitting:  fixed
shutter:  proprietary leaf
speeds: 1/25, 1/50, 1/100, 1/300
flash: cold shoe, PC connector, one sync speed
film size: 35 mm

This camera was made by Yamato Kōki Kōgyō in the 1960s.  It is  a smallish 35mm viewfinder camera from Japan made in the early 1960s.  Yamato Kōki Kōgyō made a range of cameras, frequently for private labels.  This particular model, Pal Jr, was sold in the USA by Sears as a Tower 55B.

It is a well made camera made from die cast metal with the only plastic being in the lens/shutter assembly and then take-up spool.  The size and shape of this camera are much reminiscent of the Voigtlander Vito B but with angled ends rather than rounded.

The lens is a 35 mm Yamanon lens (either made by or specifically for Yamato).  The aperture range is somewhat restricted - f3.5 to f16 - but this is a very usable range.  The diaphragm has nine blades which gives a fairly circular aperture; more circular than most modern lenses offer.  If you are interested in bokeh, this should bode well.  This lens allows focussing from a bit less than three feet to infinity.  The lens has a bluish caste so is coated at least on the external surface.  The shutter is a leaf shutter in the lens and speeds are as a Prontor - 1/25, 1/50, 1/100, 1/300 plus B.  The shutter bears no name - again either made by Yamato or specifically for them.  There is a single Happy Snapper setting - just less than f11 and twelve feet - both are marked in red on the lens barrel.

This camera is synchronised for flash - there is a PC socket on the underside of the shutter housing.  There is no indication as to whether this is M, F or X sync but given the age of the camera I am inclined to suggest it is F (for Fast flash bulbs).

Pal Jr, rear view
The top plate is fairly uncluttered.  There is a slight bulge for the viewfinder which is large enough (I can use it while wearing my spectacles).  The viewfinder has bright-lines plus secondary lines to avoid parallax errors for close subjects.  On the top of the viewfinder is an accessory shoe (a cold shoe in flash terms).  To the left is the rewind knob with a small fold-out crank.

To the right are the shutter release button (threaded for a standard cable release), the film advance lever and the rewind button.  In front of the rewind button is a window for the frame counter.  At the start of a film this is set to zero by a knurled ring around the rewind button.  The film advance lever moves through 180ᵒ for each frame.

To load a film, you turn a ring on the base plate from L to O and then the base and back come away as one piece.  Loading the film is as you would expect on a fully manual camera - insert the cassette in the chamber on the left, pull the film leader over the image gate and attach to the take-up spool.  There is a slight difference to normal here as the take-up spool turns clockwise (the film is would emulsion side outwards) so the leader is attached on the left of the spool rather than the right.

The base of the camera also features a standard (1/4 inch Whitworth) tripod boss.  This is right at one end of the camera and so is likely to be poor for both stability and level.

In use, this camera is pleasant to use.  It is small and light which means you can carry it around all day - more than I can say for some of my Zeiss Ikon or Voigtlander cameras. The shutter release falls under my right index finger and the film advance under my thumb.  The viewfinder is a bit too small but still usable.  One fault with the viewfinder that I have found is the metal surround of the viewfinder comes into contact with my spectacle lens and will result in the lens getting scratched - softer plastic/rubber is much nicer.  The settings on the shutter barrel are easy to access from above and are nice and clear.  Would be better if there were depth of field markings beside the focussing scale, but this is a cheapish camera and you cannot have everything.

I now have some test pictures from this camera.  In general I am well pleased.  There is a lot of vignetting on a couple of frames but not in general.  I clearly have had an issue focussing this camera, but many are in good focus so I cannot blame the camera!

Braun Paxette IIM

Braun Paxette II M
lens: Steinheil Munchen Cassarit
focal length:  45 mm
apertures: 2.8 to 16
focus range: 1 m to infinity
lens fitting: 39 mm (non-Leica)
shutter: Prontor SVS
speeds: 1, 2, 5, 10, 25, 50, 100, 300
flash: m, x, v  PC connector
film size: 35 mm

Braun made collecting their camera tedious.  They didn't bother putting model names on their cameras.  OK, this says "Paxette" but that is a range of cameras not a specific Braun camera.  My other Braun camera also says 'Paxette' and they are clearly different models.

The basic body of the design is the same but this current model has no extinction meter (no great loss) but does have a rangefinder (no great gain) and an exchangeable lens.

The film advance is a lever advance but it really is just a lever stuck on a knob winder.  It requires two full strokes to advance the film one frame - a bit awkward and not really any better than a simple knob would be.  I suspect the main advantage of adding the lever was a marketing one rather than a practical one.  The second travel of the film advance cocks the shutter and reduces the film counter by one (this camera counts down from the length of the film to zero).

Film rewind is still a knob and I prefer this to the small cranks that became popular through the 1960-s, 70s and 80s.  If a maker fits a rewind crank then it should be a sizeable one as on a Zeiss Ikon Contessa LKE

This camera does not have the extinction meter that my other Paxette has.  In its place is an uncoupled rangefinder.  This is adjusted by a small vertical wheel which works well enough but is a bit on the small side for my fingers.  As the rangefinder is uncoupled it is necessary to read the distance from a small window by the adjustment wheel and then transfer this reading to the focussing ring on the lens.  Guessing the distance is easier with a bit of practice and just as accurate with the lens stopped down to f8 or so.  The rangefinder and focus ring are both marked in meters which is unusual in an official import from Germany - the back of the camera is clearly marked "Made in Germany" so it is an official import.  My other Paxette has the focus ring marked in feet, so it is not a case of Braun not having the resources to produce market dependant versions.

The shutter is a Prontor SVS which was very much the standard shutter with serious cameras at this time. (1953 or so).  Compur shutters have something of a better name but I have never had a Prontor shutter of fifty or sixty years age be anything but excellent.

Shutter speeds seem to be about right.  I have no way of testing them but the manufacturers were happy with +/- 20% of the marked speed.  Half a stop out is not a problem  - half a stop is when the 1/300 speed is actually 1/225 or 1/450 seconds.  Your negative will be well exposed with that much error.

The shutter also has a PC (for Prontor Compur) flash connector with M or X flash synchronisation and V (V= Vorlaufwerk) for delayed exposure settings.  It is general wisdom not to try the V setting on old cameras as this can fail and prevent the shutter working at all.  Sure enough, when I tried 'V' it failed.  It took a bit of coaxing to get the shutter to fire.  In fact, I had to manually move the shutter blades (something else you should never do) while depressing the shutter release.  Not recommended and in future I shall heed accepted wisdom and leave the 'V' setting alone.

The iris diaphragm has (I think) twelve blades giving what is very close to a circular aperture - good for those concerned with bokeh.  The lens itself is a Cassarit 45 mm lens with a maximum aperture of f2.8  The Cassarit lens has three elements.  I can see no evidence of any coating (usually visible as a blueish sheen) but coatings were normal by 1953 and I suspect the lens has at least some coating.

The shutter release is the same as on my other Paxette - a bit of a hair trigger - but is rendered safer by being stationed between two of the stanchions which hold the shutter housing in place on the front of the camera.

Camera with back/base removed

Loading the camera is simple.  You release the back by turning the wheel around the tripod boss on the base (it takes quite a few turns).  The back and base come off as one piece making access to then inside easy.  There is a hinged bracket which must be moved to one side to put the new cassette in place - one the bracket is returned to its place, the cassette is held securely.  The pressure plate is attached to the camera body, not the back, and this must be raise to put the film between the guide rails (see picture).  If you forget, your film will not be exposed!  The leader of the film goes into a slot on the take-up spool - there is nothing to hold the film in place but it works well enough.
Bracket holding cassette moved to open position
Pressure plate in raised position
There is an accessory shoe on the top plate (cold shoe in flash terms) in front of which is the frame counter.  The frame counter is set by a toothed wheel behind the accessory shoe.  You need to set this to the length of the film when loading a new roll as the counter counts down to zero at the end of the film.

Rewinding the film is quite awkward.  With your right hand you have to press a small button on the top plate while with your left hand you need to partially raise the rewind knob and then turn it to wind the film into the cassette.  With such a small camera it is difficult to do this two handed.  I found the rewind knob kept putting itself back in the rest position - in this position, the knob will rotate freely and the film is not rewound.  Also, it was not clear when the film had been rewound so I found it necessary to keep winding long after I thought the film must be rewound in case I opened the back and fogged a length of exposed film.  Normally, there is a significant resistance from the film when rewinding and when the film leaves the take-up spool, this resistance is significantly reduced.  With the Paxette IIM, the awkwardness of rewinding masks this change in resistance.

I now have some sample pictures available from this camera.  These were taken on Agfa Vista+ negative film (made by Fuji, if you are interested).  They show up the susceptibility of this lens for flare and there is significant vignetting in the first picture but once you avoid light sources, the lens is quite sharp and gives good contrast.

Balda Baldessa F-LK

This is a nicely designed and made  cheaper camera from 1965.  This camera has a number of idiosyncrasies that would quickly became second nature with use.  It measures 120mm by 87mm by 70mm and weighs 441g.  This is my second Balda camera, the other being a Baldina from 1935.

Balda Baldessa F-LK
lens: Color-Isconor f2.8 45mm
shutter: Prontor 250 LK
aperture range: 2.8 to 22
speed range: 1/30 to 1/250
focus range: 1m to infinity
ASA/DIN: 11/12 to 800/30

The shutter is the lower spec. shutter Gauthier produced for coupled light meters - top speed is 1/250, the higher spec version went to 1/500.  Only four speeds are available (1/30, 1/60, 1/125 and 1/250) but this is enough if you stick to 100 to 200 ASA(ISO) film

With built-in flash gun extended
The lens is a Color-Isconar made by Isco Gottingen and is a triplet.  These lenses have a very good reputation (they certainly sell for a high price on Ebay).  The blueish tint says that they are coated as was normal by 1965.  The focussing range is normal for a viewfinder camera - one metre to infinity - with the focussing scale in both metres and feet.  Superimposed on the focussing scale  are three zone focussing icons - portrait, group and landscape.

The diaphragm will produce apertures from f2.8 to f22 which, coupled with the range of shutter speeds, gives a very useful range of possible exposures.  This camera has a built-in coupled light meter.  This is the match-needle type  and is not TTL - again, usual for this level of camera at this time.  On my camera the light meter does not respond to light.  Even when decrepit, there is usually some response so I suspect a mechanical fault - perhaps a broken wire.

The shutter release is on the right-hand front  of the camera which I do not particularly like but it works well enough.

The film advance is on the underside on the left which is very unusual.  The film loads back to front from normal cameras - the cassette goes on the right and the take-up spool is on the left.  Unusually (I said this camera has a number of idiosyncrasies) the advance is neither a knob nor a lever.  It is a key that needs to be turned exactly half a turn to advance the film one frame.  Again, this will soon become second nature even though it feels very awkward to me.

The film rewind is also on the underside and is the same as on a Zeiss Ikon Contessa.   Sliding the rewind release causes the rewind lever to pop out and rewinding is easy as the lever is much larger than is possible when placed on the top plate.

This camera has a built-in flash.  It uses flash bulbs so is M synchronised.  A lever on the back releases a spring-loaded flash reflector and a red lever on the side ejects the used bulbs.  The built-in flash is powered by a 15 volt battery.

There is also a PC connector for an independent flash gun.  As there is no synchronisation lever and bulb flash is built-in I assume that this PC connector is X synchronised for electronic flash.

The base also has a tripod bush.  The basic bush is 3/8 Whitworth and has a removable 1/4 Whitworth slug in it to suit the more usual tripod spec.

The only part I do not like on this camera is the back.This is made from a softish plastic.  Actually, it fits well and seems to seal properly, but it still feels cheaper than necessary.

King Regula Ip

King Regula Ip
 This is a quite well designed and cheap 35 mm camera from the 1950s. On looking at the Interweb to research this camera, it seems never to have been made.  This highlights a problem with the Interweb articles - they all rely on the same sources and then repeat the mistakes they find.  I have an actual example of a King Regula Ip in front of me and I am quite sure that they made the configuration of this camera.  Therefore, the Interweb articles that exclude this particular configuration are wrong.


The inside of the camera is engraved Regula Ip (not I-p), the shutter is a Prontor SV (not a Prontor S), the lens is a Cassar f2.8, 50mm, and the film advance is a knob (not a lever).



The shutter is still a manual cocking shutter made at a time when Voigtlander's cameras were self-cocking - I assume that Gauthier were still offering both options.  Similarly, the shutter release  is a lever on the shutter housing with an indirect linkage to a shutter release on the top plate.  Again, Voigtlander cameras from this time  have a direct  internal linkage between the shutter release on the top plate and the shutter mechanism.



The SV designation tells us that the shutter is synchronized for flash (s) and has a delay mechanism (V for Vorlaufwerk).  In the SV version there are separate levers for flash synchronisation (either M or X) and for delay.  In this particular camera, the delay is marked on the shutter bezel as 'M' rather than 'V'.


There are eight shutter speeds from 1 second to 1/300 seconds  and apertures from f2.8 to f16. The lens is a triplet and appears to be coated ( there is a blueish sheen to the lens).

Prontor shutters, although the poor relation of Compur shutters, are very good pieces of kit - witness the fact they are still working after (in the case of my oldest camera) 75 years with no attention or servicing.   All other parts of this camera are clearly cheap - or at least built down to a price.  The general feel of the camera is tinny especially when compared to a Zeiss Ikon or Voigtlander  equivalent.


The top plate contains the film advance knob, rewind knob, frame counter and accessory shoe.  It also has the King logo embossed in the metal just in front of the accessory shoe.  There is also a fairly crude serrated lever to free the mechanism for rewinding the film.



Inside, the take-up spool  is permanently attached and there is a toothed wheel  which engages with the film sprocket holes to advance the frame counter and free the double exposure mechanism which has no effect on the shutter itself but prevents the secondary button on the top plate from being  depressed.



The base plate is completely clear apart form the tripod boss which is the 1/4 inch Whitworth thread.  The camera back is hinged and fits without light seals which is always a plus on an old camera.
