Praktina bayonet SLR mount, 1950s-1960s | 35 mm SLR

Praktina was an early 35 mm SLR system from East Germany, separate from the more common Praktica screw-mount line. Its bayonet mount appeared in a period when camera makers were still experimenting with what a professional small-format SLR system should include.

The system supported Carl Zeiss Jena lenses and other optics, along with ambitious accessories such as motor-drive and finder options. It sits near Exakta historically, but with its own mechanical interface and system-camera ambitions.

For catalog browsing, Praktina entries are useful as early SLR evidence: designers were adapting classic Tessar, Biotar, Flektogon, and Sonnar-era ideas to reflex viewing before later Japanese bayonets standardized the market.
