PORST COLOR REFLEX MC AUTO 1.2/55mm (PK mount)

This lens happens to be optically identical to Yashica ML 55/1.2 lens, though not sure about coatings.
Probably Cosina made this lens based on Tomioka's optical design same as Yashica ML 55/1.2.
This lens is much less sharp at WO than my ML 55/1.2, it might be by manufacturing difference.

(Mr. K told us a small group of "normal lens afectionards" that at the beginning Cosina sub-contracted
to produce PORST/CHINON 1.2/55 based on Tomioka design, at the later stage Cosina designed 1.2/55
by themselves and made bunch of this fast lens under different brand names as you know well today.)
