Optics: Excellent, a few minor marks on the front element. Internal and rear elements – scratch and mark free. Rear element appears to have no visible scratches (this is rare, as most of these have scratched rear elements due to the rear lens protrusion).
Aperture: 100% Oil Free
Mechanics: Excellent – Full Restoration (Ultrasonic clean and degrease, multi-stage polishing, re-built for Leica RF optimization, new synthetic greases, new font work).
This is a very rare LTM Biogon lens, made by Carl Zeiss Jena. It is uncoated (aka: pre-war optics), its serial number dates to 1938. One of the earliest LTM Biogon copies we’ve ever come across. Lens underwent a full restoration. Upon reassembly, the optics were centered and collimated for accurate Leica RF usage.
Lens comes with a front cap, LTM to M adapter and rear ‘deep’ M cap.
