Leica's finder-less technical body — the Ic, accessory-shoe Barnack, cloth shutter, 1949.
The Leica Ic was a post-war screw-mount Barnack body introduced in 1949 as a stripped-down model without a built-in rangefinder or standard viewfinder. It was aimed at technical, scientific and copy-stand users, and at photographers who fitted accessory finders and rangefinders as needed.
It is a 35mm camera taking 39mm screw-thread lenses, with a horizontal-travel cloth focal-plane shutter and two accessory shoes but no coupled rangefinder or built-in finder. Focusing is by scale or accessory rangefinder, framing is via an accessory finder, there is no meter, and the shutter is fully mechanical and battery-free.
It suits technical and repro users, collectors, and photographers who build a system around accessory finders. The lack of a built-in rangefinder keeps it light and simple, making it well suited to fixed-distance and copy work as well as zone-focused shooting.
Check the cloth shutter for pinholes and capping and test slow speeds if fitted. Confirm the accessory shoes are secure, inspect the screw mount for wear, and verify smooth film advance and shutter cocking. Since there is no built-in finder, matching accessory finders and rangefinders adds to usability and value.
