CARL ZEISS JENA DDR / SONNAR 135MM F:3.5 / {RED} MC / M42 MO À BREST

CARL ZEISS JENA DDR / SONNAR 135mm F:3.5 / {RED} MC / M42 MOUNT.  This lens is a part of  the great Red MC's serie of fantastic lenses made before the fall of the Berlin Wall, in East Germany (DDR). However, even if this serie of lenses's mythic, this lens - in comparaison with the other ones - is not the best. But it's still a very fine 135mm ! Everything's working on this copy, but just one flaw need to be noticed: there's a little start of fungus on the front glass (gratefully, this intruder is easily removable and easy to clean : unscrew the front ring to had access to the front glass, clean it, dry it, and then, put all the things back together). There's only fungus on the very front  glass, the others are clean. (check the pictures) Please, don't hesitate to contact me  for any addditional infos you may needed. Cheers. Pierre.
