Modified old Leitz Elmar 50/3,5

Deserted old Leitz Elmar 50/3,5 murphy collapsed lens has modified to adopt on Canon EOS digital body. This lens had been thrown away to a trash because of flange distortion dropping down by mistake, so I happen to the situation and got I it to survive a miserable antique on digital format. For ordinary use 1 m to infinity in the state of holding and in case of close up exposure to 1/3, the barrel is extended anteriorly. Modified pancake lens, probably smallest and lightest in the world, would be an all-mighty 50mm standard lens. Sharpness and resolution capability is enough for me and the lack of color balance would be easily compensated if a convenient Photoshop software is applied.
