Isoly is a series of medium format viewfinder film cameras made by Agfa and produced from 1960 to 1971. These cameras use 120 film for 16 frames of 4x4cm. Also, diapositive films can be used. The different models are distinguished by their lens and shutter specifications. They were offered with different lens options. Isoly, later renamed “Isoly I”, still retaining its character as the basic model. The Isoly name was used again in the 1980s for a 35mm camera named as the Agfa Isoly 100. The Isoly has a single shutter speed of 1/30 of a second and a focus distance (in meters) of 5 to infinity in sunlight, or 2.5 to 5m in close up. The Aperture size is 11; 16, it has a self-timer, flash shoe, and a ¼” 20 thread tripod hard point. The Isoly instructions recommend B/W ASA/ISO 40 film for sunlight and ASA/ISO 100 film for dull days. Overall the camera is very forgiving of the available light given such few settings.
