Non-Ai 10.5cm f/2.5-22 Nikkor-P Auto Telephoto Lenses
With such a rich and colourful background occurred during the rangefinder days, it was no surprise that when the reflex F-mount 105mm f/2.5 Nikkor-P Auto lens was eventually introduced in June, 1959, it has instantly became a clear favorite and most Nikon photographer usually have a 105mm telephoto lens in their equipment inventory. The 105mm focal length comes midway between those of 85mm and 135mm and thus, it was very appealing for all round usage during those days. Naturally, the superlative image quality the lens provides was also one of the main reason contributes to its widespread popularity. Compared with normal lenses, this lens has a focal length about twice as long and a picture angle about half as wide. This enables the photographer to take pictures in a more natural perspective, an important factor for photography such as portraiture, a popular topic among amateur photographers.

But seemingly, its popularity was also attributed on its convenience in lens handling where advantage of direct reflex viewing provided by a SLR camera has opened a new dimension for telephoto lenses where previously using telephoto lenses on rangefinder cameras are tedious and a unassuring process.

In fact, most people may not even have aware during those rangefinder photographic days, Nikon has provided not just a single unit, but two Nikkor lenses at this focal length to photographers, a 10.5cm f/2.5 Nikkor-P and 10.5cm f/4.0 Nikkor-T. The optical design of 5 elements in 3 group used in the 10.5cm f/2.5 Nikkor-P was carried forward from the rangefinder days in a revised F-bayonet mount. However, it was not until in 1971-1973, the lens was finally went through a major revision to its optical design where the existing 5 elements in 4 group was used for the first time. On the other hand, the slower speed 10.5cm f/4.0 Nikkor-T was very rare in number because it was only being marketed after the Nikon F was introduced. Information for the lens was scarce but finally, I managed to extract some basic information via Robert Rotoloni's superb references on "Nikon Rangefinder", published by Hove Collectors Book series.
The single-coated 10.5cm f/4.0 Nikkor-T was in fact, introduced after the reflex Nikon F and a bayonet F mount was also available. Interesting point is its unusual 3 elements optical design.

Early Nikkor 105mm telephoto lenses has a distinctively satin chrome finishes. Some versions may also have a black paint finish. However, all of these non-Ai 105mm lenses with the bright chrome ring have been gradually phased out in stages. By 1965, when the first Nikkormat model FT/FS was introduced, many of the original Nikkor 105mm lenses have been updated with newer physical appearance (such process lasted until early '70). Versions such as all matte black finish in exterior appearance also may have been appeared during this period.
Another enthusiastic Nikon user who did not want to be named (but has his e-mail bounced when I sent him a thank you note... please reply to me when you see this site going live as I wish to provide the appropriate credit to you) mailed me an image which indicated there was at least an early version of this lens which has the minimum aperture fixed at f/22 instead of f/32. Further, a red "R" is used to indicate the infrared red focusing index and the distance numerals have not painted in yellow color yet. This version may also has a flat but ridged and textured aperture ring.
Generally, subsequent versions have metallic silver lens barrel and the focusing ring were changed to a deep scalloped design. The aperture ring may have gone through some similar changes as well. The later pre-Ai version usually can be distinguished by a diamond ridged type aperture ring. Most of all, early versions may not be multicoated and they usually have an amber yellowish tint. Generally, I would believed Nikon NIC lens coating process was only being introduced in versions that has the revised optical design which happened mid between 1971-1973. That may has altered colour appearance of its front lens element where those series exhibit a greenish tone.

Roland Vink has done a fabulous job by painstakingly compiled a list of serial numbers for various possible versions of this evergreen classic telephoto lens. Information published here may be quite useful to broaden your personal knowledge towards the background and history relating to this famed optic. As at 23rd September, 2001, this is what Roland Vink has compiled thus far; although it may not be 100% accurate but you may help to make it better by informing him about your version if it differs from what it has within the compiled lens listing:A 10.5cm/2.5 tick mark 120102 - 120106 - 121034 - ? 02/59 - ? 5/3 A 10.5cm/2.5 Kokagu, plain ring, no screws ? - 121118 - 152753 - ? ? - ? 5/3 A 105/2.5 Kokagu, plain ring, no screws ? - 152292 - 166928 - ? ? - ? 5/3 A 105/2.5 Kokagu, scalloped ring, 5 screws ? - 172151 - 282578 - ? ? - 03/71 5/3 A 105/2.5 Kogaku, scalloped ring, black 407301 - 407528 - ? 12/70 - ? 5/4 A 105/2.5 Nikon, scalloped ring, black ? - 412434 - 471485 - 473834 ? - 1973 5/4 C 105/2.5 500001 - 507794 - 553157 - 571564 1973 - 03/75 5/4 K 105/2.5 673101 - 690848 - 716560 - ? 09/74 - 1977 5/4 AI 105/2.5 740001 - 740376 - 887328 - ? 1977 - 09/81 5/4 Ai-S 105/2.5 built-in hood 890001 - 893583 - 1048549 - 08/81 - 5/4
Note: I remembered up to early eighties, Nikon was still offering services to modified older Nikkor AUTO lenses to Ai-Spec (in fact, the 105mm lens pictured above was actually an AI-modified version ). Some publications and online resources called these 'AI' Nikkor as 'AI d' - I am not so used to term used and has always wondering who was the genius behind such designation and its true meaning.

"... This lens is the early NKK Nikkor-p Version Serial No. 208617. It has been machined to allow use on AI series manual focus cameras and the notch index pin has been removed. The glass is in excellent condition, no scratches or flaws. There are no indexing numbers applied to the back rim for finder viewing. The machining isn't the prettiest job, however it works properly. ..."
