Tessar T 50mm f/3.5 Carl Zeiss Jena M42 №3577587

Tessar T 50mm f/3.5 Carl Zeiss Jena M42 №3577587 This lens was converted and adjusted in my workshop from Exacta mount to M42. Infinity is available.. The lens lubricant has been replaced with a modern one. The glass has been cleaned inside and out with Zeiss products To install on a modern camera, you will need an adapter with an M42 thread. Important: there should be nothing at the end of the thread, otherwise the lens will not screw in completely. See last photo.
