AUTO mamiya/sekor  SX  1:1.4  f=55 mm

m42_mamiya_55_1.4_SX

This is the fastest lens available for the MSX/DSX series.  It was the standard lens for the Mamiya DSX 1000 B.  The optical quality is - like most standard lenses - excellent.  The large f/1.4 aperture is a pleasure to use for manual focusing since DOF is so shallow wide open.  Since the MSX7DSX series allows open aperture metering, this is really a strong benefit.

Pictured left is a later version of this lens which already has the focal length imprinted on the aperture ring (like it became standard with the CS lenses for the NC series and the E/EF lenses for the Z-series).

The lens design is identical to the 55 mm 1:1.4 for the TL/DTL series.
