Here is the excerpt from Princelle book: " In 1962, GOMZ become LOOMP (Union of Optico-Mechanical Enterprises of Leningrad). The LOOMP logo appears briefly on a few SMENA-8 cameras as well as on a version of the amateur cine camera, the Sport-2. On January 1st, this industrial complex become LOMO ...." (Princelle 2nd edition, p.49)
Although Princelle talks about Smena-8 Loomp only, we all know about the existance of Smena-6 Loomp version for sure. Listing my records I have found that even early version of Voskchod camera had such markings, and the Lubitel-2 ... Following the logic, it's possible even to find Leningrad, Smena-5, Sputnik or maybe another same period cameras with Loomp markings...
I'd like you to share your experience in finding these cute LOOMP cameras ...
I have an interesting Lada movie camera of Yellow paint series with LOOMP around the lens and Lomo ensignia (triangle and lens) in the original lens cap. It dates from 1965.
