In 1962 Smena producer GOMZ became LOOMP („Leningradskoje objedinenije optiko-mehanicheskich predprijatij“). Need to mention, that LOOMP name as rule wasn‘ t used for camera markings and such cameras with LOOMP markings are quite rare. Only in 1965 Smena producer received permanent and very well-known name „LOMO“ (Leningradskoje optiko-mechanicheskoje objedinenije).

Smena-5 camera designed to use thermoplastic instead of bakelite. Lens T-42 with GOMZ logo, serial number under shutter housing. Strap lugs on body. Sunshade reverses on lens to provide protection. Very seldom to meet camera.

PK2305. An earliest so far known version of Smena-5 camera. The body has smaller dimensions (!). Top plate is speckled and close to black, with no decorative rim at the body margins. The surface of bottom plate is totally plain, without any border risings. Shutter speeds are written on shutter faceplate (1/125s is not mentioned at all). Lens parameters still old style 1:5.6  F-4 cm. Different design of rear door lock.  The GOMZ logo on the rear door is bigger size. There are some differencies inside the camera either [1].
