Between 1958 and 1962, VEB Zeiss Ikon Dresden manufactured the Contax FBM SLR camera. A synonym of this model is the Pentacon FBM, a name that was mainly used for export products, while in the GDR the name Contax was established.
Functionalities of the camera
Lens selection
One of the striking features of the Contax FBM is its extensive compatibility with various lenses, made possible by an M42 lens mount. This opens up a wide range of creative possibilities for photographers through the use of different lenses.
The standard lens commonly used is the “Carl Zeiss Tessar” with an aperture of 1:2.8 and a 50mm focal length. The aperture, which ranges from 2.8 to 16, allows photographers to experiment with different depths of field and manage a wide variety of lighting situations.
Shutter mechanism and exposure time
The Contax FBM is equipped with a reliable and precise horizontally running cloth focal plane shutter. It offers a wide range of exposure times from bulb to 1/1000th of a second, allowing photographers to effectively capture diverse subjects and scenarios.
Focus and flash functionality
Manually focusing the camera allows users to make conscious decisions regarding image composition. In terms of flash options, it has a sync socket (X-contact) on the surface, although it lacks an accessory shoe.
Light meter and viewfinder
With an uncoupled selenium exposure meter secured by a protective cover, the Contax FBM assists photographers in setting the perfect exposure. The prism viewfinder, equipped with an image field lens and a sectional image rangefinder, enables a sharp and precise view of the target subject.
Film handling and additional features
The film is transported using a knurled screw, with the shutter release strategically positioned at the front in an inclined position, complemented by a cable release thread. The camera is also equipped with useful extras, including a self-timer, a film type indicator under the rewind button and a film counter located below the knurled screw for film advance and tension.
Film material for the Contax FBM
The Contax FBM is optimally tailored to the 35mm format. Fortunately, there are still a variety of film options for color and black and white photography in this format.
For colorful images, the Kodak Ultramax 400* is an excellent choice, while the Ilford FP4 Plus* is ideal for black and white shots. Both films stand for consistently high quality and reliable results.
In terms of development, the color film is designed for the C-41 process, which is offered by numerous specialized photo laboratories. Many drugstores also offer this service for color films. Monochrome films, on the other hand, offer various editing options that can be achieved both in professional photo labs and at home with the right equipment.
