Industar-69 28mm f/2.8 M39 Lens – Soviet USSR Wide-Angle Pancake for Mirrorless / Macro
This listing is for a vintage Industar-69 28mm f/2.8 wide-angle lens, manufactured in the USSR for the Soviet Chaika half-frame camera. It features a compact pancake design, Tessar-type optical formula, and is known for its sharpness and contrast when stopped down.
The lens has an M39 screw mount but uses a shorter flange distance than standard rangefinder lenses, which affects compatibility (see below).

⚠️ Compatibility Note:

Does NOT focus to infinity on most standard M39 rangefinder or LTM adapters without modification
-
Can be used for macro / close-up work as-is
-
Can be modified (trimming the rear or adjusting flange) to focus to infinity
-
Can be adapted to mirrorless digital cameras with proper spacing or helicoid adapter
🎯 Why It’s Special:
-
Compact wide-angle “pancake” design
-
Rare Soviet 28mm focal length
