Bellows-Nikkor-P 105 mm f/4.0

Developed in 1969. This lens is designed exclusively for use with the Bellows Focusing Attachments. The main feature of this lens is - Focusing is only possible with a bellow unit. All Bellows-Nikkor lenses have NO focusing mechanism, distance scale nor automatic aperture coupling and is built exclusively designed for use on the bellows unit. As previously Nikon only offers BR-1/BR-2 Macro Adapter Ring that allowed reverse mounting of any of the Nikkor lens with 52mm-front thread on the Bellows Focusing Attachments for macrophotography. And there was no specific close-up lenses for such specific purpose. So, for convenient copying of your color slides and black-and-white transparencies, you can only use the Slide Copying Adapter PS-4 or PS-5 on the bellows Models such as PB-4 or PB-5. While in any other combinations, you can only depends on lens board of the Bellow Unit that swings and shifts to increase depth of field and the whole unit can be moved on the lower track for fine focusing. Naturally, Micro-Nikkor lens such as the old 55mm f/3.5 is a good choice but the lens is too short to potray a natural perspective with its relatively short focal length.

Some may also use a later BR-3 Adapter which serves as a connecting adapter to couple the bellows of the Slide Copying Adapter to the rear of the lens which is reversely positioned. However, since it was pretty difficult to always use any lens reverse mount for working with a Below Unit and thus, Nikon designed a lens exclusively for the bellows attachments, the original Bellows-Nikkor 135mm f/4.0 was introduced as early as later '50 for such application to work in conjunction with those early versions of Nikon designed Bellow Unit.

The Bellows-Nikkor-P 105mm f/4.0 was a subsequent model to replace the earlier Bellows-Nikkor 135mm f/4.0, BOTH of these lenses have NO focusing mechanism, but they will let you take pictures continuously from infinity to 1.3X with the PB4 or PB-5 (or 1.0X with the PB-3). If you're conducting critical reproduction work calling for high magnifications, such as copying documents, maps and pictures or photographing small objects and specimens, use the Bellows-Nikkor lenses with other Nikon dedicated accessories such as Repro-Copying Outfit Model PF gives you more flexibility with the firm support you need when your Nikon F or other Nikon bodies mounted with any of the above close-up attachments. Naturally, Nikon SLRs that has removable viewfinder system works best in such a setup especially in Repro-Copying outfit is vertically mounted and viewing, focusing and precise picture composition is easier with a finder such as right angle or high magnification finder.

Naturally, most of us may not be experiencing such a pain to setup macrophotography with Bellow Unit now but those days, it was a pain as there was no automatic diaphragm and you need to stop down the lens reversed mounted to ensure depth of field is well covered for any given aperture. Focusing is a tedious process too and since most Nikkor lenses are not designed to work in such extreme close focus distance and other optical aberrations also affect its optical performance. Using a Bellows-Nikkor lens is more comfortable and assuring with results.

NOTE;- Compare this 105/4 Nikkor-
P with the Nikkor-T 105/4 rangefinder telephoto lens

These compact close focus lenses permit crisp and sharp close-ups with ample working distances. Continuously focused from infinity to 1.1X with the PB-3 Bellows, or to 1.3X with the PB4 or PB-5. The Bellow-Nikkor 105mm f/4.0 lens which has a straigh forward 5 elements in 3 groups optical formula that provides excellent flatness of image field actually is a superb close up lens that gives superb resolution for close-ups and macrophotography.



It has no focusing device of its own - it is focused by the extension or contraction of the bellows focusing attachment, so, please DON'T mistaken it as with other normal Close-up Micro-Nikkor lenses. The manually preset lens diaphragm can be stopped down to f/32 with 1/3 intermediate click-stop settings. (Black dots between the inscribed f-numbers indicate the two intermediate settings between the inscribed f-numbers).

With the long focal length of 105mm, the lens offers natural reproduction of perspective, while affording the photographer greater working distance for better subject handling and illumination, should you require it.

The lens has a similar design with other lenses introduced at the same period, in a silver-chrome lens barrel and an aperture ring in a black-finish scalloped design. Some versions in black was also believed to have been seen. Further, two known versions that have its lens data engraved outside the filter ring while another was engraved inside (See picture at left). The lens was also believed not to have been multicoated.

<<< --- Note the lens data of this version was inscribed inside the filter ring.
