I have the Chinon version of the same f/1.7 lens. Still have to properly test it, I expect the same very high quality of the other fifties, and of the 55mm f/1.4 and f/1.2.
I have both 55mm's in PK mount, with MC. The faster one is one of the best lenses I ever tried. Ever.
I'm starting to believe that you can't go wrong with old Tomioka made fifties...
Quote: FANTASTIC lens. Mine didn't have the hood and caps and for some reason the aperture lever had been filed down but the glass is superb, as you will find out shortly
happy days
The old Pentax macro 4/100mm is very sharp. Though I found that my example doesn't like strong light sources within the frame. Maybe there is some haze on the inner surfaces of the glasses.
