Russian Catadioptric or Mirror Lens - ZM-5A (3M-5A) 500mm F/8.
Russian made JSC "Lytkarino Optical Glass Factory" LZOS based on Maksutov's design.
This lens succeeded the original MTO-500 lens, which was a heavy, brass unit. "MTO" stands for "Maksutov's Tele Ob'ektiv". ZM stands for Zerkal'nyi (Mirror) Maksutov's.
The later 3M-5CA was redesign from 3M-5A cutting size and weight ( 3M-5A weight = 1.225 kg) to 0,62 kg by removing tripod collar and build in hood.
