For sale is a beautiful and highly sought-after Minolta MC Fish-Eye Rokkor-OK 16mm f/2.8, one of Minolta’s most iconic vintage wide-angle lenses and a serious bit of glass for collectors, film shooters, adapted mirrorless users, and anyone chasing that proper 1970s optical weirdness in the best possible way.
This is a full-frame diagonal fisheye lens, giving an ultra-wide 180° angle of view across the diagonal. Unlike circular fisheyes that create a round image inside the frame, this lens fills the full 35mm frame while still giving that dramatic fisheye rendering: bowed horizons, exaggerated foregrounds, huge depth, and a wonderfully immersive look.
It’s a lens with a lot of character, but also genuine optical pedigree. The original Rokkor-OK optical design used 11 elements in 8 groups, and this formula was later licensed by Leitz for the Leica Fisheye-Elmarit-R 16mm f/2.8, which says a fair bit about how respected this design was.
