Agfa Standard cameras are a range of metal-bodied folding cameras, some models for plates and pack film, and others for roll film. They were made by Agfa from about 1926, when the company had recently become part of IG Farben and taken over the Rietzschel factory, until the early 1930s.[1] It is clear from patents filed by Rietzschel that the Standard range of cameras was already planned by the company before the change of name.[2]
There are plate cameras in 6.5×9 cm and 9×12 cm sizes, and roll film models for 6×9 cm on 120 film and 6.5×11 cm on 116 film. Both plate and roll film cameras were available in a normal finish, with black leather and bellows, or a Luxus finish with light brown leather. All are easily identified by the name 'Standard' below the lens and shutter.
The cameras have a variety of lenses, including the Double-anastigmat Helostar, and the Trilinear (one of Rietzschel's lenses). The Agfa Anastigmat was available as an f/7.7, f/6.3 or f/4.5. Even in the plate cameras, where the lens carriage slides on rails, the lens is mounted in a unit-focusing helical mechanism (i.e. the whole lens moves, not just the front element). This mechanism is frequently stiff because of dried grease.
Plate model 208 (for 9x12 plates; the second camera illustrated here) has front rise; there is no shift. The lens carriage on this model latches at the infinity-focus position,[2] at which the helical mechanism gives focus down to two metres, but the carriage can be drawn further forward to obtain closer focus, down to about one metre, using a scale on the right of the bed. Some of these cameras have double-anastigmat lenses, in principle separable, but the bed (with a simple pair of fixed rails) is not long enough to give infinity focus with the front group removed. Instead, slip-on front-mounted Verlängerungslinsen ('lengthening lenses') were available as accessories: model 'A' extends the focal length by a factor of 1.3, and model 'B' by 1.5.[3] This model seems to have been discontinued before the smaller ones: a 1930s Agfa brochure no longer offers model 208 (roll-film and 6.5x9 cm plate cameras are still listed); the Isolar, with a more conventional lens carriage, rack-and-pinion focus and both rise and shift, is the only 9x12 camera offered.[3]
The shutter is usually the Automat everset shutter illustrated here, with speeds 1/2, 1/5, 1/10, 1/25, 1/50 and 1/100 second, plus 'B' and 'T'. This has the Gauthier logo on it. The cameras were also available with a Compur shutter, giving 1 - 1/200 or 1/250 second plus 'B' and 'T', with a self-timer.
The cameras all have a brilliant finder, which rotates for portrait and landscape orientation, and a wire frame finder. Plate models can be used with a ground glass focusing screen.
A Luxus roll-film model was available with a slim coupled rangefinder.[4]
The roll-film cameras have spool-holders that hinge out of the camera body for more convenient loading.[2]
