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.
The Solida III takes 120 film and produces a 6 cm by 6 cm negative – twelve frames to a roll of film.
lens: Schneider-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 Schneider-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 leaf shutter 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
