To na tablice wedruja dwa szkla:
1. CANON 50MM f/1.2 RANGEFINDER.
2. Zuiko 55mm/1.2

I teraz mala ciekawostka:

To my knowledge, all 55mm/1.2 lenses are single coated and marked "G.ZUIKO". A major change occured around S/N 136xxx when the rare earth (radioactive) lens element(s) were replaced with non-radioactive material. This change might coincide with the change to a black front ring. Both versions have an amber coating, but those with the radioactive element(s) are reported to have some radiation induced yellowing which shows on slide film.
