Czajka 2M is a version of the second version devoid of a light meter. Design was also improved, on which Chayka 3 was later modeled.
Czajka is a series of simple, well-made half-frame cameras (18 x 24mm) produced by MMZ (later known as BeLOMO).
The name was probably given in honor of the first cosmonaut Walentyna Wladimirowa Tiereszkowa ("Czajka" is the code pseudonym of the entire space operation, in which the woman took part).
All Czajka's were neat compacts, equipped with a decent shutter with five exposure times (1/30, 1/60, 1/125, 1/250, B) with a synchronization socket, as well as an Industar-69 2.8 / 28 lens.
