Carl Zeiss Jena 5cm f/2 CRF lens converted to Leica M mount with full RF coupling from 0.7m to Infinity. Polished silver finish. Lens is single coated.
Mechanics: Fully ultrasonically cleaned. CNC modified to permit closer 0.7m minimum focus distance. Polished silver finish with black fonts. New synthetic greases used inside aperture control and helicoid system. LTM to M Bayonet: 6-Bit Coded
Brass sub optical block.
Optics: Very Good condition for age. There is the usual micro air bubbles inside from usage of early German Schott glass. There are some cleaning marks mostly on the front element. Would advise using a front filter at al times to continue to protect the front element.
