Nikon 7.5 mm f/5.6 FISHEYE-NIKKOR

Although this lens has been around since 1965 which remained in Nikon product listing up to 1970, this fisheye lens was one of the less known optic from Nikon. This all-embracing lens, which was considered a unique optical achievement by Nikon during those days, "sees" a full 180 hemisphere - everything in front, above, below and on both sides. It produces this extraordinary subject view as a 23mm diameter circle on the film. It is a fixed focus lens, weighing around 11 oz (315g) and many sources said it was actually introduced aim to replace the 8mm f/8.0 version of the Fisheye Nikkor. You have to make used of the accompanied accessory finder to give you approx. picture composition. The finder which can be mounted onto the flash coupling at the side of the Nikon F and Nikon F2. One significant drawback of this fisheye design is, other than it has only fixed focus and need mirror lock up, It is also advisable to use the camera only with an eyelevel finder as bulkier Photomic finder may obstruct proper usage of the lens.

Deisgnwise, this lens shares many similarities with the Fisheye Nikkor 8mm f/8.0 lens but it comes with a full stop faster in lens speed. It was introduced in October, 1965 and discontinued in February, 1970. Probably another lens of similar class but slightly shorter in focal length Nikkor Fisheye 6mm f/5.6 which was introduced in late 1969 and generally seen as an "upgrade" or replacement for this lens.

The advantages of the Fisheye in special effects photography are obvious. Less obvious, though no less significant, are the many applications of the Fisheye in scientific and industrial work. Just like any other older fisheye lenses, six filters are built into the lens on a rotating turret. Supplied with a Fisheye Finder.

Relative: A fixed focus, preset

AF-Nikkor Fisheye 16mm f/2.8 D |

I have seen some older catalogue where it was still selling along with the older Non-AI Fisheye Nikkor 8mm f/2.8 Auto Nikkor lens which generally seen as the replacement of this lens with retrofocus design that carries a new level of flexibility offered incomparable by older Fisheye lens design to permit direct reflex viewing. Well, some may also asked why there was such an odd "7.5mm ? Nikon may have thought there was no necessity to see this focal length overlapped by such small margin between 6mm and 8mm. By early '70, this lens has been written off and omitted in the product listing in some official Nikon publications and replaced with the 8mm f/2.8 and/or the mighty 5.6kg Fisheye Nikkor 6mm f/2.8.
