Silent SLR Praktica SR 899 (GSK) with Maksutov reflector telephoto lens

MfS/HVA, GDR (loan DR. Heinrich Peyers)

The Praktica GSK was developed in the 1970s at Pentacon in Dresden on behalf of the Operativ Technischer Sektor (OTS) of the MfS. Instead of the oscillating mirror, it has a fixed semi-transparent mirror made of a special film, fully automatic exposure and motorized film transport.

Additions included a long film magazine with 17m of 35mm film for 450 exposures (seen here), a data back, an external control unit, and special lenses. The mounted lens is a mirror lens MTO-11CA of the Makutsov type. This type of lens was originally developed by Dmitri Maksutov (1895-1964) for astronomy.

High-resolution images can be recorded at a very long distance. This model was used on a stationary camera by the Stasi for surveillance purposes. The manufacturer of the lens is ЛЗОС, the Lytkarino Optical Glass Factory near Moscow.
