24mm f/2.8 Nikkor-N Auto (Non-Ai)

A 2.5cm f/4.0 Nikkor-W wideangle lens was introduced by Nikon for the rangefinder series camera that came with both a bayonet and screw mount as early as 1953. Other than the 2.1cm f/4.0-5.6 auto Nikkor-O ultrawide, the 2.5 cm was once termed as ultrawide lens during that era. Eventually when the reflex Nikon F SLR camera was debuted in 1959, the first 24mm lens designed specifically with a reflex F-mount was finally being introduced in June, 1967. The Nikkor-N 24mm f/2.8 Auto lens has a retrofocus design, it was based on a creative design concept by Nikon optical engineers, combines a super picture angle of 84° and coupled with a fairly fast speed at f/2.8, it was the fastest lens among the same focal length lenses available during that period. The lens also incorporated an automatic diaphragm.

NOTE:- Refer to the Rangefinder Nikkor lenses section for more info Correction of image quality at close distance was outstanding in this Nikkor wideangle lens. Coupled to the focusing ring, an automatic optical mechanism built within ensures satisfactory good performance will deliver over its entire focusing range - from infinity to the closest distance of 0.3m. The design makes back focus clearance long enough to provide more uniform brightness in every corner of the picture image. The ingenious optical design made possible with a great reduction in its overall size and weight. Thus, you may say this lens was the first Nikkor lens that employed the innovative "Close range correction" (CRC) system.

Considering the fact that minimum focusing distance achieved by the W-Nikkor 2.5cm f/4.0 (1953) for the Nikon rangefinder system is just a poor 4 ft ! The performance of this Nikkor 24mm f/2.8 designed for the reflex Nikon cameras was indeed outstanding and it has become an instant hit among many Nikon users who has long been long for a good, high performance wideangle lens at this focal length. The design of the focusing grip was of a traditional old- type in deep ribbed scallop fashion and with a chrome silver lens barrel. The aperture ring followed a similar design with a slightly wider grip (not the diamond ridged design as with newer series of Nikkor lenses). Most of these older series of Nikkor 24mm wideangle lenses has a minimal aperture scale of up to f/16 only.

Like some of the older series of Nikkor lenses, the lens coating for the front element is deeply coloured. Some versions has a "C" after the "Nikkor-N" denotes lens coating applied and black finished on the lens barrel. Versions that followed has the minimum aperture from f/16 improved to a smaller scale of f/22 - which may have been introduced after 1975. Many of these non-Ai 24mm wideangle Nikkor lenses still surface regularly in public/online auction sales and it is good to check if those have been Ai-modified for better compatibility with your Nikon Ai bodies before any sensible decision being made to purchase them. However, if you own any Nikon SLRs made before 1979, that should be fined. Credit: Images of the Nikkor 24mm f/2.8 non-AI wideangle lens displayed here courtesy of Mr "Michael H.
