The Fish-Eye Rokkor 16mm f/2.8 is a prime fisheye lens produced by Minolta for Minolta SR-mount single lens reflex cameras, introduced in 1969 to replace an earlier fisheye lens, the UW Rokkor 18mm f/9.5. It is a full-frame fisheye lens with a 180° viewing angle across the diagonal.
This lens was licensed by Leitz and released for Leica R mount cameras as the Leica Fisheye-Elmarit-R 16mm f/2.8; it also was released as an autofocus lens for Minolta A-mount system cameras.
Minolta updated the design several times during the course of production:[1]
The original design, by Toshinobu Ogura,[2] used 11 elements in 8 groups, as designated by the -OK suffix. Lenses sold in the United States starting in 1973 were given Rokkor-X branding. Most of the updates since the original release were cosmetic, aside from the 1980 update, which changed the design to 10 elements in 7 groups and reduced the size and weight,[1] designed by Mitsuaki Horimoto.[3]
The 11e/8g Ogura design was licensed by Leitz and assembled by Minolta for Leica R-mount cameras; the Fisheye-Elmarit-R was released in 1974 and continued in production until 2001.[4] When the Minolta A-mount system was released in 1985, the 11e/8g Ogura design was revived as an autofocus lens, the Minolta AF Fish-Eye 16mm f/2.8 (1986). Production of this lens continued after the A-mount system was purchased by Sony.[5]
Due to the extreme angle of view, the front of the lens does not have a mount for filters; four filters for black-and-white and color photography are built in and selected by a rotating dial near the front on the body of the lens. Filter selection varies by the lens design. The 1969 version includes normal/UV (1A), orange (O56), yellow (Y48), and cooling (80B) filters.
