Fisheye-Nikkor 8mm f/2.8 Auto

Introduced in 1970. This is the first Fisheye Nikkor lens that has adopted the automatic aperture diaphragm (See earlier
Fisheye-Nikkor 8mm f8.0). The lens speed of f/2.8 is the fastest in the array of Fisheye Nikkor lenses. The most significant design of the lens when compared with older versions is it obviates the need for locking up the mirror and use of special accessory finders as with many older fisheye Nikkor lenses. This is the brightest Fisheye lens and is provided with the automatic diaphragm coupled to the exposure meter. Thus, viewing and focusing can be done on the focusing screen with the f/2.8 brightness. Another significant difference is the ability to focus with the new lens design where the mechanism provides graduation both in meters and feet up to 0.3m and 1 ft. Older versions of Auto Fisheye-Nikkor lenses have fixed focus design.

The front lens element has a dome liked design. As the meter-coupling prong is provided with this lens, Exposure determination is possible with the diaphragm fully open, as in the case of other Nikkor Auto lenses. The 8mm f/2.8 Fisheye-Nikkor Auto covers 180° angle of view adopting the equidistant projection formula like the Fisheye Nikkor 6mm f/5.6, Fisheye-Nikkor 7.5mm f/5.6 and Fisheye-Nikkor 8mm f/5.6 lenses.

This fisheye lens produces a circular image on the film (If your priority is to get a full frame fisheye visual effect, go for the Nikkor16mm Fisheye lens which was designed specifically for that ). The front element of this lens has a very large diameter of 123mm (4-27/32 in.) but the lens weighs only 1 kg (2.2 lb).

The automatic diaphragm stops down to f/22. There are five built-in filters on a rotating turret (see picture below) which has added a layer of flexibility to the lens functionality. It is a lens combining some good elements in its overall compactness, its fast lens speed, automatic diaphragm and through-the-lens viewing capability, as well as the unique fisheye pictorial qualities it delivers.

It is excellent for the initial approach to creating fisheye effects in general as well as special-purpose photography. This fisheye lens produces a circular image on the film. The automatic diaphragm and the bright f/2.8 aperture facilitate viewing and focusing through the viewfinder. Its compact size and light weight allow handheld shooting. All these advantages contribute to the ease of handling and the versatile applications of this lens in commercial and advertising photography as well as in scientific photography, photojournalism add news and sports coverage.

As this lens has quite a few versions which have been produced and refined over the years, some of them have been surfacing every now and then at popular used outlets such as public auction houses. You can add a little premium on newer series as I think the coating plays an important role. Although after 1970, Nikon started to apply NIC to most Nikkor lenses, but even then, I still think NIC has also gone through a few cycles of improvement. The large coverage of the lens and its huge external lens element would need extra care in that sector for even distribution of light onto film.
