Mamiya RB67 50mm F4.5 Sekor C Wide Angle Lens -Clean-
This is the desirable 50mm wide angle lens for the RB67 and Pro-S (it will fit the SD with an adapter). It corresponds to about 28mm in the 35mm format and is wide enough to get a lot into the frame without distorting perspective.
The lens is very sharp and has a close range correction for superior image quality; there is a secondary focus lever on the front that you use to optimize the lens for various focal distances. For fast paced shooting you can set the lever in the middle of the range (and you are no worse off than with a lens without this adjustment).
This lens is in excellent working condition with little cosmetic wear. The glass is clean and scratch-free with an aperture that is dry and snappy. The focus is smooth.
Lens caps are included.
