Isoly is a series of medium format viewfinder film cameras made by Agfa and produced between 1960-71.

These cameras use 120 film for 16 frames of 4x4cm, the reduction of 6x6cm. Also, diapositive films can be used. The different models are distinguished by their lens & shutter specifications. They also offered with different lens options also. Isoly, later renamed Isoly I was the basic model.

The Isoly name used again in 1980s for a 35mm camera as Agfa Isoly 100.
