Voigtlander Vito CLR



This is a development of Voigtlander's Vito range. That started as the folding 35 mm Vito of 1939. The folding Vitos were replaced by the rigid bodied Vito B in 1954 . The Vito B sired a small range - Vito BL, Vito BR and Vitomatic. Then in 1960 came the Vito C and a small range - Vito C, Vito CD, Vito Cl, Vito Cs, Vito CLR and Vito CSR and these were followed by the Vito Automatic (very different to the Vitomatic of 1957).

So, this is the third range of Vito cameras. The name, Vito CLR, tells us it is the C range with a light meter and rangefinder. Both the light meter and the rangefinder are coupled to the shutter.

As I usually do, I shall start with a physical description of the camera, followed by notes on using it.

My camera is the third iteration of the deluxe version. Deluxe means there are slight variations on the layout of the top plate and I get a ring of black leatherette around the base of the shutter housing. The camera is somewhat bigger than the Vito B - it measures 125 mm by 85 mm by 75 mm and weighs xxxg. The main difference in appearance is that the camera now has a 'standard' hinged back fastened with a catch on the left-hand side. This is much easier to use than the Vito Bs somewhat strange back (although I like the Vito B's back for its idiosyncrasy).

On the top plate on the left is a recessed rewind knob. This has a turnable film reminder which can be set to either blue or yellow - sunlight or artificial light? Just right of centre is an accessory shoe. As was usual at the time this camera was made, there are no flash contacts so this is a cold shoe. To the right of the accessory shoe is the window for the light meter. This is reflected into the viewfinder so you can set the exposure without removing the camera from your eye.

Top plate - (C) J. Margetts
On the back of the camera there are three items. On the left is the viewfinder eyepiece. This has bright-lines directly on the rear glass with parallax markings for close-ups. Below the viewfinder and slightly to the left is a lever to raise the rewind knob and free the film advance mechanism. To the right of the back is the film advance lever. This moves through 220 degrees as far as I can judge and advances the film one frame and cocks the shutter.

The front of the camera is a lot busier. At the top is a chrome rectangular bezel. This contains on the left (while looking at the lens) the light meter lens, above the shutter housing the rangefinder window and on the right the viewfinder window.

In the middle of the front, just off centre, is the shutter housing. This contains a Gauthier Prontor 500 LK shutter. The outer ring on the housing is the focussing ring. This ranges from 1 metre to infinity (my camera is marked in metres rather than feet which usually means a grey import but the body is clearly stamped 'Made in West Germany' so it is a factory import). This ring has three Happy Snapper settings at 1.3 m, 3.2 m, and 10 m. The last one is the hyperfocal distance at f5.6 and the middle one is the hyperfocal distance at f16.

The next ring is the shutter speed ring - this adjusts from 1/15 to 1/500 and B. This is also used to set the film speed for the light meter - you need to depress a small black tab immediately behind this ring while setting the film speed. Behind the shutter speed ring is the aperture ring which runs from f2.8 to f22. this ring has two sizeable black tabs attached which makes finding the ring by feel easy - this is important when setting the exposure with the camera at your eye.

In the centre of the shutter is the lens - a Color-Skopar f2.8 50 mm lens. This is front cell focussing so not ideal but will still produce excellent images. The lens will take 32 mm push fit filters and lens hood. To the left of the shutter housing (again, while looking at the lens) is the shutter release button. This is threaded on then underside for a standard cable release. Below the shutter release is a PC flash connector.

The base of the camera has then usual 1/4 inch tripod boss - slightly left of centre and slightly forward - and a frame counter. The frame counter counts down so tells you how many frames you have left.

I have completed a test film using Fomapan 200 Creative. This has shown up a problem with the camera - one the seller drew my attention to - the exposure meter under-exposes by around two stops. So, using this camera I need to set the meter for ASA 50 rather than the correct ASA 200. I suspect this is due to the selenium  sensor in the meter deteriorating. This is something we are always warned about with old selenium meters but not something I have actually come across before (it could, as the seller suggested, be the setting ring having moved from its correct position, but I doubt it).

Because of the metering problem, the negatives are very thin and getting a good scan has been difficult. tonal range is not as it should be and there are very visible horizontal lines in each picture. There is also some evidence of a light leak in the pictures - it is on the left-hand side which means it must be from around the hinge of the back. In some pictures it is not very evident, so, perhaps, if the pictures were exposed correctly, it would not be a problem. There are no foam light seals in this camera to deteriorate.

Second test film results are below the monochrome results.

Second test - with Agfa Vista+ colour film, processed by Snappy Snaps in Lincoln.  Negative density is fine, so the earlier problems were either lack of use or my developing of the film.

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.

Voigtlander Vito B and Vito BL



Voigtlander Vito B & BL

Voigtlander Vito B

Vito B (BL lower down)

This is a very nice camera from the 1950s (1956 for this camera). It is well designed and well made – no plastic (at least not visibly) and the pressings and millings are neatly finished. It is a pleasure to look at and to hold.

lens:  Color-Skopar
focal length:  50 mm
apertures: f3.5 to f16
focus range: 0.8 m (2.6 ft)
lens fitting: fixed
shutter: Prontor SVS
speeds: 1 s to 1/300 s
flash: PC socket
film size: 35mm

Voigtlander's Vito B was their first rigid 35mm camera - made in Braunschweig, Germany.  It was brought out in 1954 and was a Vito II replacement for the excellent .  It was discontinued about 1961.  The Vito B spawned a number of other cameras - Vitomatics I and II and the BL series.  These had built-in light meters and, in the case of the Vitomatic II, a coupled rangefinderThe price new in England was around £24 for the model with the Prontor SVS shutter.  In 1959, a new model was brought out with a larger bright-line viewfinder.  The camera is only 115 mm wide, 70mm front to back and 70 mm high. This fits well into the hand and is small enough to fit into a coat pocket. It also has a lens hood which adds a further 25 mm to its length. This is the successor to the Vito II folding camera and is both slightly smaller and slightly heavier than its predecessor but with the disadvantage for carrying that the lens does not fold away. The main structure of the camera is die cast with pressed chrome plated covers.

The film advance lever falls nicely to the thumb in use but travels well to the front of the camera which is a bit awkward in use. There is also an accessory shoe on top which is designed for a rangefinder as much as for a flash gun. There is a PC  (for Prontor Compur) socket on the underside of the lens for a flash gun – the camera can synchronise for bulb flash (M) and electronic flash (X). The flash synchronising lever is also used to set the shutter delay timer (V for Vorlaufwerk). The shutter is cocked by advancing the film – an improvement over the Vito II which had a manual cocking lever on the shutter housing. It is also an improvement over the later Vito Automatic I where the shutter release also cocked the shutter during the first part of its travel.

The lens is a 50mm Color-Skopar with a maximum aperture of f3.5. This lens is based on Zeiss Ikon's Tessar lens – four elements, two of which are cemented together and air gaps between the others. These lenses are surprisingly good, especially if you stop the lens down to f8.   Focussing is by way of the whole lens assembly so image quality is not reduced as you focus closer.  The lens takes a 32 mm push fit filter or lens hood.

Focussing is either scale focussing which relies on you knowing the distance to the subject or zone focussing with two settings – o which focusses the lens to between 15 feet and infinity and ߜ which focusses the lens to between 8 and 18 feet. Both of these need the aperture to be set to f5.6 or better.   Voigtländer  produced a small rangefinder to fit on the accessory shoe which allowed accurate measurement of the distance but this was not coupled to the focusing and needed the user to read off the distance from the rangefinder and then set that distance on the focussing ring.

Behind the lens is a either a three speed Pronto or an eight speed Prontor-SVS shutter.  There is also a shutter delay timer but on old cameras it is supposed to be a bad idea to use this – although on my 56 year old camera it works fine on fast speeds (1/100, 1/300) but not at all on any of the slower speeds. The shutter works quite well at faster speeds from 1/300 to 1/25) but is very slow indeed on the slower speeds – 1/10 second is actually above five seconds! This probably means that the shutter mechanism needs a service but I have to ask if the cost of this is warranted. I have found on other cameras that the shutter works better after it has been used a few times. When acquiring a new old camera it is worth bearing in mind that the cameras has probably been sitting unused in a drawer for the last thirty years or so.


The film chamber opens in an unusual way – first you open a small door in the base and then the back will swing open.  This is designed to make inserting a film easier and works quite well but for some reason Voigtländer abandoned this on subsequent cameras. Fitting the film is extremely easy. The film sprocket holes fit over a large toothed wheel which serves to cock the shutter when the film is advanced. For this reason, an empty camera will not allow you to fire the shutter. When the film is fitted, you have to turn a toothed wheel on the underside to set the number of frames available. This number appears in a window just above the lens and shows the number of frames still available – the camera counts down from 24/36 to zero. There is also a strange prong just below the lens – this appears to be a foot so the camera will stand on a flat surface when using the shutter delay timer but no mention is made of it in the manual.

The view finder is very small being 8mm in diameter at the rear and 10x16 mm in the front. This means the view is rather smaller than real life  at about two thirds but is adequate and certainly bright enough.

The pictures that this camera produces are good even by modern standards.


Vito BL

The Vito BL is based on the Vito B mark II - that is, the version with the larger viewfinder. There are two changes. One is the addition of a light meter to the camera. The second is these of an EV enabled shutter (I am given to understand that some Vito B cameras also had EV enabled shutters but I have never seen one). The shutter is a Prontor SVS - the same as the Vito B above.

The light meter uses a selenium cell which does not need a battery to work. Selenium light metre's get an undeservedly bad press predicated on their losing sensitivity over time. While this is theoretically correct, I have yet to see a selenium meter that was not still accurate, even with meters that are over 55 years old.

With the design of the meter, film speed (ISO) is set by turning a knurled knob on the back of the top plate. This moves a series of numbers into view. Each series is identified by a letter - each letter represents a different ASA/ISO rating. B is 12 DIN/12 ASA, C is 15 DIN/25 ASA, D is 18 DIN/50 ASA, E is 21 DIN/100ASA, F is 24 DIN/200 ASA and G is 27 DIN/400 ASA. For those who are not aware, films speeds double with 3 added to the DIN rating. 24 DIN is twice as fast as 21 DIN. With ASA/ISO, double the film speed has double the ASA rating. 400 ASA is twice as fast as 200 ASA.

Meter set to F - 24 DIN or 200 ASA/ISO
To read the meter, turn the knob on the back until the letters representing your film speed comes into view.  You then point the camera at the subject and look at the needle in the meter display. It will be sitting in either a white or a black zone. At the left edge of the zones are the EV values. The EV value adjacent to the zone the needle is in is then set on the EV range on the shutter - to do this, you have to depress a chrome lug on the left, besides the EV 2.

Knurled meter knob below meter
The EV enabled shutter has the usual shutter speed and aperture rings but they are linked by a third ring - the EV ring (EV stands for Exposure Value). When you set the EV value from the light meter, you link a range of shutter speeds to a range of apertures. You can then turn the shutter speed ring to select a combination of shutter speed and aperture but only those that give the required exposure (it is rather like P mode on a digital camera in that a respect). See three photos below. The range of EVs available are from 2 to 18. EV 2 is 2 seconds at f/3.5 and EV 18 is 1/300 seconds at f/22 A summers day in England is usually going to be about EV 14 to EV 15.

In every other aspect, this Vito BL is the same as a Vito B.
