Auto Mamiya-Sekor Macro  CS  1:3.5  f=50 mm

cs_50_macro_3.5

This lens is very rare.  It took me a long time to track one down, and that was only possible with the help of Xavier, a very friendly guy from Spain who also uses Mamiya NC cameras.

I think this lens is so hard to find since the Mamiya NC cameras were usually sold together with a standard lens, and only very few people were willing to spend the extra money on a macro lens with the same focal length as the standard lens.  This macro lens was also one of the more expensive lenses back then (around US$ 200).

The lens focuses down to a maximum magnification of 1:2.  There is also an extension tube “Macro CS” available for this lens for 1:1 magnification.
