Carl Zeiss Biogon 21mm f/2.8
Carl Zeiss Biogon 21mm f/2.8 for Contax G mount in excellent condition. With an advanced, near-symmetrical optical design, this lens sports extremely low distortion and excellent optical correction. Glass is clean, focus linkage works as it should, and there is only minor cosmetic wear. Includes Contax GF-21mm accessory viewfinder (in great condition, but left the factory with the rear mask slightly off kilter–this doesn't affect its use), original case, and manual.
