Nikon Ai Fisheye-Nikkor 8mm f2.8

The first Nikon fisheye with an automatic diaphram, and the first which does not require mirror lock-up. This permits accurate framing using the viewfinder, and TTL metering. The lens speed of f/2.8 is the fastest of fisheye Nikkors. This lens covers 180° with equidistant projection like the earlier 7.5mm f5.6 and 8mm f8 Nikkors.
