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).

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.

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.

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.

Franka Solida III camera

The first Vintage camera that I bought was a Franka Solida II.  The Solida III is basically the same camera, as you would expect, with a different lens and the addition of a non-coupled rangefinder.
Franka Solida III

The Solida III takes 120 film and produces a 6 cm by 6 cm negative - twelve frames to a roll of film.

lens: Scheider-Kreuznach Radionar
focal length:  80 mm
apertures: f/2.9 to f/22
focus range: 3 ft to infinity
lens fitting: fixed
shutter: Prontor S
speeds: 1 second to 1/250 + B
flash:  PC socket, no X/M switch
film size: 120


The lens is a Scheider-Kreuznach Radionar 80 mm, f/2.9 lens.  This is a bit unusual as the aperture sequence usually goes to f/2.8 rather than f/2.9.  The minimum aperture is f/22 which is more than small enough coupled with the 1/250 shutter speed.  It is probably worth noting that the physical size of the aperture at f/22 on a medium format camera is much larger than f/22 on a 35 mm camera and so diffraction effects are negligible and so give sharper images than an equivalent lens/aperture would with 35mm.  With an APS C format digital camera, the difference will be even sharper.  The test film showed this lens to be better than adequate, at the least.

The shutter is a Prontor S by Gauthier, offering shutter speeds from 1 second to 1/250 plus B.

Happy Snapper settings are indicated in red and are around f/9 and twenty five feet, giving a depth of field from twelve feet to infinity.  There is also a secondary happy Snapper setting of f/9 and eight feet which gives you a depth of field from six feet to twelve feet - presumably for portraits.

There is the usual delayed action lever giving  a delay of around eight to ten seconds.  A PC socket is provided but no synchronisation lever so the flash synch could be either for bulb or electronic flash. Given the camera's age, I suspect it is synced for bulbs but whether for M or F bulbs I do not know.

The rangefinder works well and the two images are nice and clear.  There is enough separation between the two rangefinder windows (43 mm) and there is enough movement on the adjusting wheel to make the device effective.  Unfortunately, as a non-coupled rangefinder, it is necessary to read the distance off the rangefinder and set it on the lens focussing scale.  I find guessing the distance and using a smallish aperture to be fine and I don't think I would use this rangefinder very much.

The other niggle with the rangefinder is that it uses a separate eyepiece to the viewfinder making focussing and composing totally separate activities and further reduces the utility of the rangefinder.

There is a safety interlock between the film winder and the shutter release meaning it is impossible to make a double exposure.  There is a (very) small window beside the film winder which shows red when the film has been wound on.  In fact, it is only necessary to turn the film winder 3/4 of a turn to reset the shutter which is not enough to wind on to the next frame.  Not having a manual for the camera, I had thought the shutter faulty before I finally twigged the purpose of the small window.

The red window on the back which allows you to read the frame numbers has a sliding cover to prevent the fogging of panchromatic film.  Loading is easy.  Both the film spool and the take up spool are contained in hinged housings which hold the film securely until the back is closed.

The pressure plate is significantly larger than the frame size (80 mm wide) which means that the film is kept nicely flat - not always the case with medium format cameras.  The lens standard pops out nicely when the button on the base is pressed - this camera is fully self-erecting.

In use, this is not anywhere as easy as the Franka Solida II.  That camera opens vertically with the baseboard at the bottom under the lens. This Solida III opens sideways so that the baseboard is to the right of the lens when you are using the camera.  This leaves very little camera for the right hand to hold on to which is rather awkward. With the fingers of the right hand curled, it is quite usable and the forefinger drops quite nicely onto the shutter release.

Small items - there is an accessory shoe - cold shoe in flash terms - and a single tripod socket on the base which is to UK/USA standard.  Lastly, the film winder has a film speed reminder on its top, with DIN/ASA numbers from DIN 12/ASA 12 to DIN 24/ASA 200.  On a camera of this age, it is worth noting that the ASA numbers are the "new" ASA scale

Agfa Billy Record


Agfa Billy-Record
Agfa Billy-Record landscape format


This is a fairly standard full frame 120 film camera from the mid 1930s.  I think this camera is a grey import - no "made in Germany", distance scale in metres and the tripod socket is continental rather than UK or USA.

The camera takes eight pictures on 120 film which makes it an expensive camera to use.  There are two finders: a brilliant finder and a two frame Galilean finder.  I can never get on with brilliant finders - too small mostly.  The shutter is a Prontor II from Gauthier and the lens is Agfa's Apotar 10.5 cm focal length and f4.5 maximum aperture.  This lens performs very well - with colour as well as monochrome.  Lenses from the 1930s were usually colour corrected even though colour film was unusual.  This is because the new (for the time) panchromatic films were sensitive to all colours and non-colour corrected lenses would produce a very soft image.

Shutter speeds on the Prontor II are 1, 1/2, 1/5, 1/10, 1/25, 1/50, 1/100 and 1/150 as well as B and T.  1/25 and 1/50 seem very slow by modern standards. but the 6cm by 9cm negatives would be unlikely to be enlarged.  For most people, contact prints would be normal.  The lack of flash synchronisation and the 1/150 maximum shutter speed date this to the first Prontor II design and so dates the camera to between 1934 and 1938.

The lens focusses down to less than one metre to infinity.  On my camera, the lens will not focus to infinity - either because the grease on the focussing thread has solidified (something Agfas are notorious for) or because someone has attempted a repair (also common on old cameras).

As was normal until the mid 1950s, the shutter release lever is on the shutter housing.  As was also normal from 1930ish, Agfa provide a secondary shutter release on the camera body which is connected to the lever on the shutter housing by an articulated link.  This is a seriously weak link and barely works on my camera.  When opening the camera, there is a significant danger of the release link missing the lever on the shutter housing.  Agfa actually stress the importance of this in the manual for the camera.  The long term effect of this link missing its proper location is that the link has bent and frequently dis-articulates itself.

There are the two tripod bushes we would expect on a camera of this format and date.  One is on the base board - centrally placed which makes fitting a tripod easier than on some cameras - and one near the centre of the base.  Both are 3/8 Whitworth which is larger than most tripods use.  My other cameras from this era have a 1/4 Whitworth insert and these may well have been present at some time.
