Lovely Summicron Rigid in very good condition considering its age
Optics are very well preserved and produce lovely characterful images 
Focus has just the right amount of resistance and the infinity lock is working well
Aperture clicks in full stops
Do note that there are what look like very thin cleaning marks/potential scratches on one inner element - these are not excessive and bear no effect on the final image 
Included is the lens, original front cap, and generic rear cap
