For M42 Film or Digital (will adaptto modern digital cameras like Sony a7 series (full-frame) or a6000/a6300 APSC with adaptor not included)

I collect lots of vintage lens and have been very meticulous on condition when acquiring (i.e. no haze, little if any cleaning marks, and NO FUNGUS with smooth. Will upload photos of actual lens.

This lens has been cleaned, lubricated, and aligned by ex-Carl Zeiss Jena engineer in UK! This is the very collectible red MC version (believed to be the last version).

Includes front and rear cap.

Reluctant sale but I have too many 50mm's!
