Non-Ai 28mm f/2.0 Nikkor

Between the early version which have starting serial number from 280001 and the AI Nikkor which starts from 335001, there could well be another update of the lens with a more modern Nikon lens cosmetic which was believed happened in 1975 (see picture below). Nikkor 28mm f/2.0 was one of those lenses which has clearly benefited from many fruitful optical research Nikon has developed over the years and thus, but if you are considering acquiring such a fast optic, please ensure the lens has at least AI-modified in order to be use with your AI camera bodies. Depends on your objective and /or the camera models you own (Ai or non-Ai), the lens remains a very attractive investment even at used condition or considering giving it a Ai-conversion if your camera is a Ai-Spec Nikon camera body.

Some of the Nikkor 28mm f/2.0 featured here which believed to have been introduced in February, 1976 may bear "Nikkor-N C" which was the earlier batch, the subsequent ones have omitted such designation and has only "Nikon" and "Nikkor". The main visual difference was the rubberized grip has three rows (Generally, the rubber grips Nikkor lenses introduce during this period was a little flat in height but Nikon improved their height slightly after AI lenses was introduced) and the aperture ring is diamond-ridged for better grip.

With the brightest maximum aperture at this very popular focal length, and one of the brightest apertures available for Nikon/Nikkormat cameras, the 28mm f/2.0 Nikkor is a "natural" choice for available-light photography. Incorporated within this superb retrofocus optic is a highly corrected 9 element, 8 group configuration with a Nikon close range correction system for lop quality images at the very close 0.3m (1.0 ft) minimum focusing distance of the lens. The optical formula proves to be a very highly successful design as the lens remains literally unchanged optically throughout its entire product life span (except the Ai-S version after 1981). The picture angle of 74' offers ample widefield coverage for a variety of picture-taking applications, including industrial, architectural, land scales, travel and news shooting; and with a bright aperture of f/2.0, viewing and focusing are fast and precise.

Another advantage of the wide maximum aperture of this lens is the control of depth of field that is possible via careful selection of the shooting aperture; the 28mm f/2 affords far greater flexibility than possible with wider angle lenses.

When used with a bellows focusing attachment, this lens can provide up to an impressive
8.7X magnification for a wide range of close-up applications. The 28mm f/2 Nikkor lens accepts the common 52mm screw in type accessories.
