Probably a 35mm Praktica, made in Dresden. At one point they had 10% of the world market, and probably nearly all of the market in the Soviet sphere.

A fellow in my unit in Sacramento had one. It was solidly built, but the East German battery for the exposure meter was weak - he got a ride in a HH-53 to take aerial photos of the unit building, and the downdraft from the rotors chilled the battery below where it would provide any power, so all his pictures came out nearly black.

Maybe all the market in East Germany but in USSR proper Zenit (https://en.wikipedia.org/wiki/Zenit_(camera)) was the absolute market leader.
