The 50mm Zeiss Planar is an extraordinary and very fast (f1,4) hunk of glass. It is simply an exceptional lens. New it sells for almost RRP £560.00 so grab yourself a bargain.

In perfect working order and with all documentation, packaging and in addition the appropriate original Zeiss UV protective filter on the front of the lens (these are expensive in themselves). The lens has been cared for like a baby. 

Good luck.
