Minolta AF Fish-Eye 16mm f/2.8
Originally produced by Minolta, and currently produced by Sony, the AF Fish-Eye 16mm, is a prime Fisheye lens compatible with cameras using the Minolta A-mount and Sony A-mount lens mounts. It is a full-frame fisheye lens with a 180° viewing angle.
The front of the lens does not have a mount for filters. Rather a number of filters are built in: Normal, 056, B12, and either FLW or A12. The filters are selected by a rotating dial on the body of the lens.
