Rollei-HFT Zeiss Planar 50mm f1.8 Prime Lens for SL35 -Clean-
This is a beautiful standard lens for the Rollei SL35. It has Zeiss Planar glass and a solid metal construction. You should look up some sample images from this lens, I think that you'll be impressed.
This one is in excellent condition with light wear. The glass is clean and scratch free with no haze or fungus and only a light amount of dust inside. The focus is smooth and the aperture is dry and snappy.
