Adox Golf 63 S

At one time Adox were a major photographic force.  German in origin, they were bought by Dupont. The Dupont company was sold to Agfa (and so became German once again) and Agfa did not use the Adox brand name so their registration of the name lapsed.  Almost immediately, Canadian and German companies registered the name, neither of which have any connection with the original German company (although the modern German Adox make excellent films).  The Adox name is now used exclusively by Adox Fotowerke GmbH although two companies own the rights to the name in different countries.  The Adox that made this camera are the original Adox - the owners of the name being Dr C. Schleussner Fotowerke GmbH - and the camera was made between 1954 and 1959.  It is at the bottom of the range of Golf cameras.
Adox Golf S

lens: Adoxar (made by Will Wetzlar)
focal length:  75 mm
apertures: f6.3 - f22
focus range: 1m to infinity
lens fitting: fixed
shutter: Gauthier Pronto
speeds: b, 1/25, 1/50, 1/100, 1/200
flash: PC connector
film size: 120



The internal construction of the Golf resembles Agfa cameras of the period.  The visible parts of the body are made of pressed steel rather than the machined die-cast aluminium alloy used by the likes of Zeiss Ikon and Voigtlander.

The bottom and top plates are pressed aluminium which has not been anodised - it is very prone to corrosion. Again, this is very different to the practice of Zeiss Ikon and Voigtlander who used chrome plated brass.

That is the negative part over.  The design is good, even if basic. It is easier to load than my Zeiss Ikon medium format cameras of the period, with hinged spool holders (which is also reminiscent of Agfa).

The lens base board snaps fully open at the press of a button on the top plate and there is a double exposure interlock.

So, more specific details.  The outside of the camera first.  The size of the camera is basically dictated by the film size - 120 - and the frame size - 60 by 60 mm.  The camera measures 135 by 90 by 40 mm when closed and opens to 90 mm. It weighs 475 grams. This is very light compared to Zeiss Ikon and Voigtlander models and is down to the use of pressed steel instead of die-cast aluminium.

The lens is an Adoxar 1:6.3 75 mm lens.  It seems to be have been quite the fashion to have a lens name end in 'ar'.  This lens was made for Adox by Will Wetzlar (now a part of Helmut Hund GmbH). The lens is housed in a Gauthier Pronto shutter (which earns the camera the designation 'S') rather than the usual Vario shutter. This is a good, well made shutter which is unlikely to give trouble even after sixty-odd years.  Gauthier shutters were designed to run dry - that is, with no lubricant. This means there is no oil to dry out and become sticky and there is nothing to trap dust and foul the movement. I have yet to come across a Gauthier shutter that did not work right, even after sitting untouched in a drawer for forty years.

The top plate is uncluttered. The only controls here are the shutter release and film advance.  The shutter release is a simple aluminium button, threaded for a standard cable release. The film advance is a knurled knob. Between the shutter release and the film advance is an indicator window for the double exposure interlock. The shutter release will only work if this indicator is red. When you press the shutter release, the indicator changes to white and the shutter is now locked. When you advance the film, the indicator will change back from white to red and the shutter is unlocked. It takes about a half turn of the film advance knob to achieve this.

In the centre of the top plate is a simple accessory shoe. There are no electrical contacts here and flash is connected via a PC connector on the top of the shutter housing. Flash is synchronised for fast flash bulbs.  As this camera has a leaf shutter, shutter speed is not so important as with a focal plane shutter. The manual (which I have!) says the camera will work fine with electronic flash as well.

The bottom plate is plain apart from a linear machining and a centre tripod boss (1/4 inch Whitworth).

The back of the camera has no features apart from a red window. The position of this window is dictated by the negative size which is 6 by 6 cm. 120 film has three sets of numbers on the backing paper - one for full frame (6x9),one for half frame (6x4.5) and one for square (6x6). The set of numbers for 6x6 runs down the middle of the length of film, so needs a central window.
Adox Golf S - front

When winding on a 120 film, you have to look through the window at the numbers on the backing paper. The numbers are typically preceded by a row of circles of increasing size to show the number is getting closer.  For those only experienced in 35 mm film (or digital), when the film is finished, there is no need to rewind. You wind on until all trace of the backing paper has disappeared from the red window - then you open the camera, carefully take out the film and stick the self-adhesive tab around the film to prevent it from rewinding.

Under the window, the legend 'made in Germany' is embossed in the leatherette and beneath that is 'T-YD'

In use, the base board drops down vertically. This is how I prefer it to be as it leaves plenty of room on either side of the lens for my not so small hands. My Franka folder has the base board hinged on the side and this makes it hard to hold securely.

The viewfinder is very small and I find I need to put my eye very close to it to frame the picture. This means I have to take my glasses off and then I can no longer see the picture I am framing. The shutter release falls nicely to my finger.


Sample pictures.

I am quite impressed with these.  They all came out a bit on the dark side (Gimped to get brightness where it should be) but I am impressed with the quality.  Perhaps I should not be surprised.  The lens was made by Will Wetzlar who also made lenses for Leica.

Emi K 35

Emi K 35


The Emi K 35 was made by the Oshiro Optical Works in Japan in 1956.  It is quite an attractive and well made little camera but basic in the facilities it offers.

lens:  Fujiyama Eminent Color
focal length:  50 mm
apertures: 2.8 to 16
focus range: 3 feet to infinity
lens fitting: fixed
shutter:  own make
speeds: 1/25, 1/50, 1/100, 1/300
flash: PC connector, X synch
film size: 35 mm

The camera is heavy, being made from die cast metal (presumably aluminium alloy) including the hinged back.  It measures 125 mm by 70 mm by 80 mm tall.  The main body is covered in black leatherette and the top and bottom plates are satin stainless steel.

The shutter release button is next to a raised part of the top plate and with my large hands it is a bit awkward to get my finger on it.  Film advance is by a lever.  In my camera, the spring that returns the film advance lever to its rest position is broken so it is necessary to put it back in place manually. However, the lever still advances the film and cocks the shutter, so this camera is quite usable.  

The viewfinder is small, but no smaller than Voigtlander were offering at the same time.  There are no frame lines in the viewfinder, so I assume the total image is what will be recorded on the film. On taking the camera apart to look at the broken film advance spring, I saw a square cut-out in the front of the top plate that is normally masked by the 'Emi K' logo on the front of the camera.  This suggests that a rangefinder was considered at some point in the design - either to be offered on another model or abandoned for this model.

One the left of the top plate is the film rewind which is a small crank (very small!) which is fairly difficult to use.  This crank pulls up to release the cassette for removal.  The only other thing on the top plate is an accessory shoe - a 'cold' shoe in flash terms.  For flash, there is a PC connector at the bottom of the shutter housing.

The lens is a Fujiyama Eminent Color lens.  There is a red 'C' on the lens bezel which I am sure indicates that the lens is coated (just about normal for 1956).  The whole shutter housing/lens assembly seems to be well designed and well made but feels a bit plasticky compared to Prontor shutters. Actually, the shutter housing is plastic which is not actually a bad thing so long as it is used thoughtfully.

The inside is as you would expect - a recess for the film cassette, machined guides for the film, a sprocket wheel to advance the film and a fixed take-up spool.  I am very much in favour of fixed take-up spools.  Zeiss Ikon and Ihagee both used removable spools and I spend too much of my time on my hands and knees retrieving the spool when using those cameras.  The camera back has the expected pressure plate (generously sized) and 'Zeiss bumps' in the leatherette.  'Zeiss bumps' are formed when the rivets holding components together react chemically with the metals used.  The back is aluminium alloy and I suspect the rWhitworthñ steel.

The base of the camera has a central tripod boss - 1/4 inch Whitworth.  There are no strap lugs on this camera - the manufacturers will have expected the user to use the 'ever-ready' case that will have been supplied with the camera.

Test photos


I was aware when I started that the return spring in the film advance lever was broken, but the mechanism itself seemed to work OK. As I used the camera it became apparent that the lever was not engaging with the internal mechanism properly and sometimes it took several sweeps to advance one frame.

Using this camera reminded me very much of using my Zeiss Ikon Contina Ic. They have a very similar size, shape and weight - I suspect Emi had the Contina in mind when designing the Emi K. Controls are minimal and are placed on the lens/shutter barrel. The viewfinder is nice and large and centrally placed. However, there are no bright lines for accurate composition.

The only problem I have had using this camera stems from the fact that the return spring  in the film advance lever is broken (as mentioned above). I initially thought that this would mean that I would have to return the lever by hand after winding on the film and otherwise all would be well. in fact, the film advance lever interacts with two sub-systems in the camera - the double exposure prevention mechanism and the missed frame prevention mechanism. Sometimes I would turn the film advance lever and nothing would happen, sometimes I could not turn it at all without pressing the shutter release a second time - this did not fire the shutter, it just freed the mechanism. I was never confident that the film was advancing properly. Although the rewind knob turned as I advanced the film - a sign that the film is moving - it did not turn smoothly. Looking at the prints, it is apparent that the film was not entirely moving as it should - there is slight overlap of frames - but the problem is not severe, just annoying.

Exposure of the film is fine, indicating that the shutter speeds are, at the least, close to the supposed values. I only actually used the faster speeds so I cannot vouch for the slower speeds - it is usually the slower speeds that play up first with old cameras.

Framing not quite right

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)

CMF Comet S

CMF Comet S

This is a cheap Italian camera which uses 127 film.  The makers is Bencini which is an Italian firm.  At the time this particular camera was made, the firm was called CMF Bencini.  They were made in Milan.

lens:
apertures:
focus range: 3 feet - infinity
lens fitting: fixed
shutter: simple
speeds: 1/50
flash: PC connector, M synch
film size: 127

The camera is small and light.  it is made from an aluminium alloy which is nicely polished.  It is small, measuring 10.5 x 7 x  6.5 cm.  It is a very simple camera with only two controls.  You can focus the camera - the range is from 3 feet (circa one metre) to infinity - and you can set the shutter to 1/50 seconds or B.

It is a half frame camera using 127 film.  The negative size is 3 x 4 cm which is approximately twice the size of 35mm.  You get 16 negatives on a roll of 127 film.

Lens barrel detail
The speed selector is unusual in that it is a tab that is pulled out from the lens barrel; see photograph.  The speed selector is on the right of the picture - also visible is the PC connector for flash.  This is synchronised for bulbs only so not too much now.

The viewfinder is very small - the eye piece only measures three millimetres across.  It is the smallest viewfinder I have ever seen.  However, it is still usable once I take my spectacles off.

Comet S - rear view
As a roll film camera, it is necessary to look at the red window on the back when winding on to set the next number in the red window.  As this is a half-frame camera, each number is used twice - there are two red windows - first in the left hand window and then in the right hand one.  the picture shows the two red windows, one either side of the maker's name.

Again as is always the case with roll film  (120 and 127 size) you do not need to rewind the film.  At the end of the roll, you wind the film on until all the backing paper is on the take-up spool and remove the film and spool together and stick the end of the film down with the sticky tab provided.  The spool the film came on is then used as the new take-up spool.

127 film spool
As 127 film is now quite expensive and not too easy to get hold off, I doubt I will ever use this camera.  So, no test pictures from this camera, I'm afraid, but samples can be seen here.

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.

Voigtlander Vitomatic II

Voigtlander Vitomatic II
Voigtlander Vitomatic II
This is an update of the excellent Voigtländer Vito B.  The Vito B spawned several cameras - the Vitomatics I and II and the Vito BL. This is the automatic update as opposed to the more manual Vito BL. The Vitomatic II has a coupled light meter and a coupled rangefinder added and a new shutter mechanism (the Prontor SLK-V made by Gauthier) which is needed to make use of the light meter.  Voigtlander also made independent rangefinders which were less handy in use. The lens is still a Color-Skopar 50mm lens but now it is f2.8 rather than f3.5 (this might just be the items I have - I have no idea as to the options that were available regarding lenses for either the Vito B or the Vitomatic II).


View of base plate
The size of the two cameras (Vito B and Vitomatic II - I am going to be comparing the two throughout this posting) is the same except the height.  I have a version I Vito B with a small viewfinder.  The later version II had a larger viewfinder and is also higher than the version I.  So the Vito B (II) is the same size as the Vitomatic II.  The layout of the top plate differs as the Vitomatic II has an exposure meter window but is otherwise the same. The front of the camera is also different as the Vitomatic II has both an exposure meter and a rangefinder window both of which are missing on the Vito B. There is one more change that is immediately apparent - the frame counter on the Vito B is a small window above the shutter housing with an adjusting wheel below the shutter housing.  With the Vitomatic II, the frame counter is on the base plate and has a small adjusting wheel beside the counter window.

view of top plate

The presence of both the rangefinder mechanism and the light meter means that the SLK-V shutter/lens housing on the Vitomatic II is significantly larger than the SVS housing on the Vito B. The SLK-V shutter is Voigtlander's adaptation of the standard SLK shutter - this is a light meter coupled shutter.  (Both Voigtlander and Prontor were subsidiaries of Zeiss Ikon at this time.)  The Vitomatic II is also significantly heavier – something that could not be avoided with the improved specification. So, in use, the Vitomatic II still fits nicely in the hand but is much more tiring to hold for a period of time. Using the ever-ready case and hanging the camera around your neck would obviate this but I like to hold the camera in my hand – it is more discrete and faster to use.

The coupled light meter is simplicity itself to use. It is of the match needle type with the needles in the window on the top plate. This is adjusted by turning the forward most knurled wheel on the shutter housing. When the two needles are superimposed, the camera is set for a correct shutter speed/ aperture combination. This can be varied in one stop steps by turning the rearmost knurled wheel. Moving this wheel alters the speed/aperture settings but keeps them in the correct range for a viable exposure. It is a bit like the P setting on a modern digital camera. The only drawback to this system is that the meter needles are not shown in the viewfinder so you need to lower the camera and look at the top plate while setting the exposure.


The viewfinder is a reverse-Galilean finder with a large (much larger than the Vito B) eye-piece with bright lines including parallax adjustment.  The coupled rangefinder is also simple to use – this time it is accessed through the viewfinder. The rangefinder presents the user with a bright spot in the centre of the viewfinder with two separate images. The user turns the focussing ring (the smaller, forward most knurled ring) until the two images are superimposed – the lens is then correctly focussed for the part of the image in the centre spot. This is made easier by the user choosing a strong vertical to focus on.


The film chamber is accessed the same way as on a Vito B – a small portion of the base-plate is unlocked and lowered and then the back swings open. This is very secure in use and the type of accident I occasionally have with my Vito II where the catch on the back can accidentally open while the camera is in use is not possible.  The one downside is that changing films while standing in the street is cumbersome - but  far from impossible.

I now have a Vitomatic I as well.  This is the same as the Vitomatic II but without the coupled rangefinder.  I do not miss having a rangefinder as I find guessing distances works just fine - at f5.6 and smaller, the depth of field is enough to cover any slight discrepancy in the guess.

There are also "a" and "b" versions of both Vitomatics - I and II.  The "a" versions have the light meter scale mirrored in the viewfinder and the "b" versions have aperture and shutter speed mirrored in the viewfinder.

Vitomatic II in use. 

This is a fairly simple camera to use.  The light meter is not TTL so in use it is much the same as a hand-held meter.  The advantage over a hand-held meter is that aligning the match needles in the light meter window sets a usable combination of speed and aperture.  It is then simple to turn the inner ring on the shutter housing to set either a specific aperture or a specific speed according to the photographer's needs.  The shutter then selects corresponding speed/aperture to maintain correct exposure.  As this is not TTL, you do not need to fumble with the controls at eye level.  If you want to use exposure compensation you merely turn the exposure control as many stops either side of standard as you need.  As this control basically adjusts the aperture, it is possible to over/under expose by a fraction of a stop.  It is worth noting that the aperture is infinitely variable between f2.8 and f22 while the shutter speed is restricted to click-stops - it is not possible to set a speed between1/125 and 1/300, for instance.  If you try, you will get either 1/125 or 1/300 depending on the exact position of the cam inside the shutter mechanism.

This camera inherits scale focussing from the Vito B complete with two happy snapper settings of 3.25m and 10m (roughly) at f5.6.  These settings make street photography very easy.  I often keep the camera set to 1/125 and smaller than f5.6 and the focus on the distant (10m) happy snapper setting - giving everything between 4.25m and infinity in focus.  

For more critical work, there is the rangefinder.  This uses gold "silvering" of the half-silvered mirrors giving orange images in the centre of the viewfinder which are clearly seperated from the main image.  As with most rangefinders, turning the focussing knob moves one of the images - focus being achieved when the two images are exactly superimposed.  

If the lens is nearly focussed, this is quick and easy.  The downside is that focussing from one end of the scale to the other cannot be achieved in one motion but in use I am not finding this a problem.

Last comment - this is a heavy camera - particularly for its compact size - but this aids stability in use.

Voigtlander Vito II

Voigtlander Vito II

Voigtlander Vito II ready for action
Voigtlander's Vito range of cameras are 35mm cameras aimed at serious amateurs.  They date from the 1940s to the 1960s and pre-date the SLR concept.  As was normal for the time, they come with several options of lenses and shutters.
  

Camera ready for carrying.
Initially, the Vito range were folding cameras that were small enough when closed to easily fit into a pocket.  My example is a mid-dated Vito II - the Vito II model went through a number of revisions with minor details being changed with each revision.  There was one major revision which gave rise to the Vito IIa.  I also have an original Vito I.  A comparison of my Vito cameras can be seen here.

The sequence of changes in the Vito II were: 

  • 1949 Introduced 
  • 1950 Shutter release bar became shutter release button, holder for an accessory shoe added 
  • 1951 Film take-up spool is fixed and rewind knob is telescopic 
  • 1954 Accessory shoe fitted (rather than provision for one) Compur shutter available 
  • 1955 Film advance now a lever, larger viewfinder (Vito IIa) 

So my Vito II is a 1954 version although the lens serial number shows the lens was made in 1953.

So, a basic description.  The camera easily fits in a hand (my hand at any road), being 125mm long, 75mm high and 40mm thick when closed.  The lens standard is opened by a recessed button on the base - the cover is hinged on the side and the lens comes forward and locks in position.  This action is spring loaded but on my camera the spring is not strong enough to fully open the camera.  When new, it may well have been fully automatic opening.  To close the camera again, two buttons have to be pressed simultaneously and the cover pushed into place.
 
The lens on my Vito II is a Voigtlander Color-Skopar 50mm which is Voigtlander's version of a Zeiss Ikon Tessar.  This lens has a very good reputation.   It focusses down to 3.5 feet - this camera uses front cell focussing which is not quite as good as moving the whole lens top focus but this only matters for close to work and for landscapes is fine.  The results are excellent.  The focussing scale has two Happy Snapper settings - "o” which is the hyperfocal setting for f5.6 and “V” which the hyperfocal setting at f16. When the focus is set to "o” and the aperture to f5.6, the depth of field extends from 15 feet to infinity and when set to “V” and the aperture to f16, the depth of field extends from 5.5 feet to infinity.  The lens serial number dates this lens to 1953 although the camera was made in 1954.
 
The lens has a slight but definite purple tinge to it which suggests that it is a coated lens but if it is, it is still, unfortunately, susceptible to flare. Using this camera, it is necessary to remember the advice my father gave me as a child – always keep the sun behind you.
 
The aperture range is f3.5 to f16. The shutter is the cheaper Pronto shutter made by Gauthier and offers four speeds – 1/25, 1/50, 1/100 and 1/200 seconds as well a B. There is also a delay action timer which delays the shutter release by about ten seconds. This is very difficult to use as the setting lever is very close to the struts holding the lens in place.
 
This camera is old enough to need manual cocking of the shutter. The actual shutter release is on the shutter housing but it is actuated by a button on top of the lens cover – there is also a cable release socket at this position. The camera has two safety devices – first, the shutter will not fire if the film has not been wound on so no double exposures and secondly, the winding knob will only move the film on one frame without the shutter being fired. This last can be over-ridden so a part-used film can be rewound into the cassette and then refitted and would on to the next unexposed frame at a later date. This allows the photographer to change between types of film while on a shoot without wasting film.
 
The last thing to mention regarding the shutter is the presence of a PC (Prontor Compur) flash connector. There is no selector to choose between bulb or electronic flash and on the model I have (Pronto shutter) it is for F synchronisation only – i.e. the flash will fire when the shutter is nearly fully open which is intended for fast flash bulbs.  With Synchro-Compur and Prontor SV shutters, you would have X and M synchronisation available. Both the film advance and film rewind are by way of a large milled knob – one on each end on the top plate. The back of the camera fastens with a not entirely satisfactory catch. When the camera is in the ever-ready case, this will not matter but I tend to carry this camera in my pocket and I have had the back unfasten itself.
 
The viewfinder is a Galilean type and is rather small. Wearing spectacles as I do, I find it very hard to use as I cannot get my eye near enough to the eyepiece. The only other thing worth noting is that this camera has feet. This is common on cameras of this era (40s and 50s) and the feet take the form of small metal projections on the base plate and the lens door. These enable the camera to be set down on a suitable surface so that self-portraits can be done using the delayed action timer.

18 September 2012: 

This is now a favourite camera with only a few niggles.  The first is its age - around sixty years old.  My concern for its age revolve around the bellows.  These are made from some sort of oiled/lacquered cloth and eventually they will start leaking light.  I am not sure if I should tackle this by leaving the lens extended all the time and so ensuring that any small leak there might be will leave a significant mark on the film, or whether I should leave the camera closed unless I am actually taking a picture and so hastening then point at which then light starts leaking in.


The other main niggle is the position of the shutter release button.  When holding the camera, my finger does not naturally fall on the release button and I find my finger searching for it - not exactly helping to 'hit' the decisive moment.

Third niggle - the viewfinder.  It is small.  So small I can barely use it while wearing my spectacles.  This is a reverse Galilean finder - it produces a small image in the same way that a telescope does when you use it back to front.  having a built-in viewfinder in a consumer camera was a fairly new idea when the Vito II was designed - Zeiss Ikon were still using folding Newtonian finders on the equivalent (Nettar and Ikonta) cameras.  This viewfinder is much the same as the viewfinder in the later Vito B.  It was only when the Vito B had been in production for several years that larger comfortable to use finders were introduced (as they were on the new Vito C range that eventually replaced the Vito B range.

Apart from those three niggles, I like using this camera.  the rewind knob is better than a standard SLR mini lever for rewinding the film and I also like the film advance knob in place of a rapid wind lever.
