Auto Mamiya-Sekor CS 50mm f/2.0 Lens
This lens is not listed in many Mamiya NC brochures or manuals I have seen. This could be because it was introduced just shortly before the whole NC-series was discontinued.

The lens is very compact and the focusing ring is quite narrow. This might also be the reason that the focusing action is not quite as smooth as other CS lenses. However, the optical performance is excellent and almost equals that of the f/1.7 version. An advantage would be its very low weight.
