Pentax has given their cameras many names on models and series. One of the first was the Asahi Pentax K. That letter has been coming back.
We hereby present: Asahi Pentax K, Asahi Pentax K2 and Ricoh Pentax K-3:
Read and see more of Asahi Pentax K at Asahi 1952-1964
Read and see more of Asahi Pentax K2 at Pentax
Read and see more of Ricoh Pentax K-3 at Pentax K-:2009-13
Sadly not found the Ricoh XR-7 / Sigma SA-1 / Sears KS-2 camera(s) on the site. They could be produced by Cosina as well, but I have no information about this.
For an explanation of the penta mirror, please see the page "Some Definitions".My definition of PP SLR also include the penta mirror cameras.
More about Pentaflex: Probably a penta mirror, which is a lighter, less expensive, a bit darker and simpler edition of the penta prism. Text will be corrected.
Hi, Information about this camera is scarce and often differing. What is your source? Anyway, thanks for your help. Does anyone else have information about it?
