Two 55mm Asahi Pentax Super-Takumars ---

Here are Two Asahi Pentax 'Super Takumar 55mm lenses' The one on the RIGHT is the 'f2' version I was given off a jammed S1a. The LEFT one is the original 55mm f1.8 off my 1961 'Asahi Pentax S3' I noticed that on the f2 lens I could move the aperture PAST f2 and the aperture inside opened UP a fraction ! Maybe those f2 lenses are actually the f1.8 ones which Asahi Optical thought were not sharp enough so called it 'f2'

I took some tests at f2 on some grotty 1999 dated Kodak PJ800 film rated 100 ASA

The 55mm Takumars are great, in my opinion better than the 50mm f/1.4s.

I see like my ST 55/1.8, they both have the aperture running the 'wrong' way.

These are great lenses

Here is the VIDEO I did -- my 'original 1961 S3 lens ' was an 'Auto-Takumar' NOT a 'Super-Takumar' !
