Carl Zeiss Jena's standard prime for Exakta — the fast 50mm f/2 with CZJ character.
The Carl Zeiss Jena 50mm f/2 for Exakta is a vintage standard prime from the East German Carl Zeiss factory. The 50mm f/2 was the standard lens for many Exakta-mount SLR cameras. CZJ lenses are valued for their distinctive warm rendering character. The Exakta mount was one of the first SLR bayonet systems.
Optical performance has the characteristic CZJ quality — good sharpness with a warm, pleasant rendering. The f/2 speed provides useful shallow DOF. Multiple optical versions exist. CZJ multi-coating on later versions improves contrast. The rendering appeals to vintage lens enthusiasts who value character over clinical precision.
Exakta mount. Filter thread varies. Weight varies. Build quality is solid German CZJ precision. Manual focus. The Exakta mount adapts easily to mirrorless cameras. CZJ 50mm f/2 lenses are common and affordable — produced in large quantities for decades. Multiple optical designs exist across the production run.
