Auto Mamiya-Sekor  CS  1:1.7  f=50 mm

cs_50_1.7

This is by far the most common and wide-spread lens for the NC series cameras.  It seems like almost every NC1000 or NC1000S comes equipped with this lens.  Therefore, the market value is not very high.  Even if the lens is in almost mint condition, you usually don´t pay more than US$ 25-30 for it.

Mamiya is renown for their lens designs, especially for their standard lenses (in 35 mm or medium format photography).  When you take pictures with this lens, you know why.  The performance is really outstanding, it is probably the best of all Mamiya NC series lenses based on the tests I had done.  And chromes taken with this lens turn out very beautiful.  This lens alone makes the NC1000S camera very usable even today.

Auto Sears/Sekor  CS  1:1.7  f=50 mm

sears_cs_50_1.7

Pictured left is the same lens licensed by Sears under the designation Auto Sears/Sekor CS 1:1.7 50 mm.  The only differences are the color of the printing and the structure of the rubber material used for the focusing ring.  The structure on this Sears lens is about the same as it was used for the mamiya/sekor SX lenses for the Mamiya MSX/DSX series cameras.
