Ever since its introduction as the first fixed-focal length wideangle lens offering "floating elements" for close-range correction of image quality, the 24mm Nikkor lens has been one of the most popular lenses in the Nikkor optical lineup. An updated 24mm f/2.8 Nikkor lens continued in the tradition of its predecessor which occurred during 1975, it also a few similar elements of a good wideangle lens such as compact size, wideangle coverage of 84' and the same close focusing system, all in a retrofocus configuration of 9 elements in 7 groups optical design.

It was an direct upgrade from the earlier Auto Nikkor, where Nikon dropped the designation of "24mm f/2.8 Nikkor-N" to just a plain product name of "Nikkor 24mm f/2.8". The feel of a modern Nikkor lens is taking shape and signaled a clear departure from the older cosmetic design used in previous AUTO Nikkor series. Picture shown at left is essentially still a pre-AI version which may require some attention when used with a non-AI camera body. One easy refernce to this lens update was the minimum aperture which expands from f/16 found on older auto Nikkor to f/22 in this series. This lens combines both factors of, as a wide picture angle and bright maximum aperture, and has outstanding distortion correction and sharp, uniformly bright images all the way up to its close minimum focusing distance of 0.3mm (1 ft)-and edge to edge.

Complementing the lens' close-range correction system and high optical performance is NIC on air-to-glass lens surfaces. This lens is an excellent lens for use in candid shooting, architectural photography, and other demanding picture taking situations; and when used for close-up photography, the floating element system ensures high performance. The all round top performance has partly contributed to its popularity.

The exterior of the 24mm f/2.8 Nikkor is fitted with the new slip free, rubberized focusing ring and studded aperture ring which departed from older Nikkor physical look. All through the-lens metering/viewing functions are retained which was provided with most up-to-date Nikon and Nikkormat series of SLR cameras which were gaining its good acceptance even to the amateur users' market during mid of seventies. IF you are owning one of these non-AI Nikkor lens, or for any reason you intend to get one of these; the best and safest solution is to locate a reputable outlet who still offer to provide AI conversion. This is necessary as it is also to ensure total compatibility with many of the manual focus Nikon SLRs that introduced later, which naturally, includes current model such as Nikon FM2(n) or the latest manual focus Nikon camera, Nikon FM3A. This lens was eventually being revised thoroughly to a new optical construction of 9 elements in 9 groups design after Nikon introduced their updated meter-indexing system, the "AI" (Automatic Maximum Aperture Indexing) in 1977.
