Leitz 5cm f2 Summitar for LTM process_ECN-2 Colour a real optical viewfinder

a real optical viewfinder

though it'll will only autofocus with AF-S types

with clear glass and smooth focusing

and nearly no cosmetic wear

so this might not be the right lens for you if you’re precious about cosmetic condition

Leitz 5cm f2 Summitar for LTM process_ECN-2 Colour a real optical viewfinderThis is a first year (1938) Leitz 5cm f2 Summitar lens for Leica Thread Mount in good usable condition, with clean glass and smooth focusing but a fair bit of cosmetic wear, mostly on the collapsible barrel. The focus tab infinity lock (the spring loaded part) is missing, which is technically a flaw but honestly, it's a usability improvement. Good imaging. A nice vintage lens with the "old" aperture sequence (to f12. 5)
