Agfa Isolette I with the Agfa Agnar lens (f/4.5 85mm), 1952-1958. With the shutter and aperture settings on the front of the lens this was an awkward camera to use.
Initially I would set the aperture using a light meter, but after a while I got used to guessing the settings and most of the time they were correct. You didn’t know you had messed up until the film got processed. Double exposures happened if the film wasn’t wound on, as there was no interlocking to prevent it like on the Praktica SLR.
It used the large 120 size film. The negatives about 60 mm square making them ideal for enlarging.
