Brief information on

Nikon / Nippon Kogaku Japan special application Micro-NIKKOR 1:5 f=7cm (70mm f/5) , Micro-NIKKOR 1:5.6 f=150mm (150mm f/5.6) & Macro-NIKKOR Series of lenses


Today, Nikon probably is more well known as a camera and lens manufacturer. But the Company was started in 1917 after merger of 3 local optical manufacturers to form an alliance known as known as Nippon Kogaku K.K. before change of name to Nikon. They produced general optical instruments such as binoculars, microscopes, eyeglasses (some products such as binoculars were marketed under the name of MIKRON and this was replaced very late with "Nikon" in 1959). On the other hand, the microscope made by the Company used "JOICO" in 1925 and changed to "NIKKO" in 1935. The Company may has also produced special requested optical instruments such as aerial surveillance equipment for military use But it was only in 1932, the trade name of "Nikkor" was adopted for the first time as the brand name for their camera lenses; while "Nikon" for camera was used only in 1946 (with the first camera, Nikon I , introduced in 1948). During the period '30~'40, they had also began production of lenses for large format cameras as well as smaller lenses even for other camera makers, which includes
Seiko Kogaku/Hansa, or more popular known as Canon today. The post war period of Nikon began shifted their attention to other areas, which includes cameras, microscopes, binoculars, surveying instruments, measuring instruments and ophthalmic lenses etc. The initial success of the rangefinder Nikon and overwhelmed popularity enjoyed with the early Nikon reflex cameras had the Company clearly established as a respectable camera manufacturer as well as extending benefit in acknowledging quality of optical instruments Nikon produced.

There are series of Nikkor lenses being produced which may had confused a of of Nikon users. Although I am not too good in the respective fields where their actual applications were actually meant for (the scope may cover from medical, scientific, industrial, IT manufacturing, biological studies, dark room, laboratory, post printing and even for cine and TV broadcasting etc.), but I simply intend to list some of them in orderly manner so as for all of us to share and/for for quick reference guide. I am equally aware there are many enthusiastic collectors of these Nikkor, so if you have other versions or possess in-depth knowledge relates to corresponding application for each type of these specialized optical series, you may contact my buddy,Rick <> where we can create another site extension from here. Thank you.

To begin with, other than the popularly known Nikon 35mm S-Mount rangefinder
Micro-Nikkor.C 1:3.5 f=5cm model discussed earlier, the Nikon Micro-Nikkor lens family actually has another two models, namely Nippon Kogaku Japan Micro-NIKKOR 1:5 f=7cm and Nippon Kogaku Japan Micro-NIKKOR 1:5.6 f=150mm. It was not exactly known both the 7mm and 150mm were made for as most often, even when the reflex- version of Micro-NIKKOR 55mm/3.5 & 105mm f/4 were in the market, many official Nikon published sales leaflet and/or Sales Manual listed the 7cm/150mm Micro-NIKKOR by by side. Few of the main differences which separate the two types were:1) The lens-mount, with the S-Mount for rangefinder, F-mount to fit the 55/105, but the 7cm/150 has neither of these; 2) Focusing range: the normal S/F-mount can be focus from nearest distance to infinity. But the 7cm/150mm were made for close focus and require bridging between camera and lens. 3) Magnification aspect. Standard magnification between the series are more of lens the same; for an instance, 1/10X for 55/3.5, 1/10X for 150/5.6 and 1/12X for 7cm. But the usable Magnification can be varied greatly and this is where the Micro-NIKKOR 1:5 f=7cm / Micro-NIKKOR 1:5.6 f=150mm truly excel from the normal Micro-NIKKOR 55/3.5 or a 105/4. For an example, usable magnification with 55/3.5 provides 1/OOX~ maximum 1X with use of accessory or extension; but an astonishing high magnification of 1/30X ~1/5X is delivered with BOTH the Micro-NIKKOR 1:5 f=7cm and Micro-NIKKOR 1:5.6 f=150mm ! In a Nikon Sales Manual, it explained Micro-NIKKORS. " .. for the field of micrographic, Micro-Nikkor lenses offer high resolution, flat ness of field and freedom from astigmatism - essential quality that are prerequisites for producing high quality microcopies or microphotographs. The special characteristics of Micro-NIKKOR series are corrected for aberrations at their standard reduction ratios, as opposed to conventional lenses which are corrected at infinity focus. Further, the diameters of front/rear element groups are larger than dimensional aperture of the lens so that minimal vignetting occurs with the lens only by moderately stopped down. However, due to their extreme flatness of field, it is vital to keep planes of object and film precisely parallel ...".

Here is a link to a Japanese Collector, Michio Akiyama, where his site has pointed to his friend's Uli Koch from Germany web page showing a
4 models of early Micro-Nikkor appeared together in a leaflet published by Nikon during the '60. By the way, Mr. M. Akiyama probably has the most detailed information on series of specialized Nikkor lenses on the web, for those who may be interested to beef up personal knowledge should take a good read at them <website in both English and Japanese>.

Nippon Kogaku Micro-NIKKOR 70mm f/5
Nippon Kogaku Japan / Nikon Micro-NIKKOR 1:5 f=7cm with separate lens tubes

I don't have much information on the lens, but as 7cm (70mm) optic is equally odd for a traditional 35mm Nikkor where it is a 40% extension in focal length as to S-mount Micro-NIKKOR 1:3.5 f=5cm (50mm). It used a similar 5E/4G basic optical design but actual dimension is different due to longer focal length of additional 20mm. It measures approx. 32mmx 45mm but weighs heavier at 180g as compared to 5cm/3.5's 144g. The MN 7cm/f5 consists of two parts with one section of lens tube has a release switch while the lens component section can be detached away from the external barrel. Apertures are marked at the front ring from f/5, f/5.6, f/8, f/11 and f/16 but there is no aperture ring nor encoded with depth of field scales. The focusing ring - not exactly a ring as the grip is a smooth surface, fixed type with no texture at all. But this was changed/improved at the later version (see below for version uses 70mm model)

<<< --- This Nikon Micro-NIKKOR 1:5 f=70mm uses new focal length scale of 70mm instead of 7cm. But the most significant change as compare to earlier model is the one-piece design used. Next, the release switch on lens barrel has been eliminated and the front section has a '60 F-mount Nikkor preset-type of early design where it can be turned to control the aperture, the scales were marked from f/5, f/5.6, f/8, f/11, f/16 and f/22.

The S/N with a rather high sequence in 6 digits numbering and this may suggest this model could be introduced at a much later date. Further, focusing collar on this version uses a typical reflex F-mount period kind of design, textured and may provide a firmer grip for whoever that is using it. No info is available for its optical composition but could be the same with the older model.

Anyone has further info ?

Suggestive Link(s):- Enrico Savazzi site has an excellent article on the lens as well as some explanation of lines resolution with Micro-Nikkor 70mm f/5.

Note: A micrometre is one-millionth of a metre (1/1000 of a millimetre, or 0.001mm). Its unit symbol in the International System of Units (SI) is µm. The nanometre was formerly called also millimicron,since it is 1/1000 of a micron, and was often denoted by the symbol mµ or (more rarely) µµ. or A unit of length equal to one thousandth (10-3) of a micrometer or one billionth (10-9) of a meter.

Nippon Kogaku Japan
Micro-NIKKOR 1:5.6 f=150mm (150mm f/5.6).
Year introduced: 1960* ; Discontinued: No exact info; * Ref:
Nikon Hand Book

Nippon Kogaku Japan Micro-NIKKOR 1:5.6 f=150mm (150mm f/5.6).
At 150mm focal length, what I can recall Nikon had only produced three lenses in the enlarger EL-series, namely EL-NIKKOR 1:4N f=150mm, EL-NIKKOR 1:5.6 f=150mm and EL-NIKKOR 1:5.6A f=150mm; and four additional Nikkor-W/SW lenses for 4 x 5 large format usage (Nippon Kogaku Japan NIKKOR-W 1:4.5 f=15cm, NIKKOR-SW 1:4 f=150mm, NIKKOR-W 1:5.6 f=150mm and NIKKOR-W 1:8 f=150mm).

Today, in the eyes of collector, Micro-Nikkor 150/5.6 is very rare piece of optic. According to literature, this lens came after the 7cm and possibly only having "mm" version and no "cm" marked for its focal length description). According to one leaflet distributed by Nikon, it explained the development of the lens was cater for increase of demand for high resolution lens for films with a width of 70mm in microfilming sector where larger size originals such as blueprints and weather charts that have small characters or letters. So, this lens basically was meant for microfilming which may require high resolution image capture over a large picture area. It also meets requirements in the filed of photoengraving as well as in specific field use for electronic industries. The Micro-NIKKOR 1:5.6 f=150mm used a different new optical construction of 6 elements in 4 groups design which Nikon claimed to provide the highest resolution lines (150 lines/mm@f8) among the few F-mount Micro-NIKKORs and the Micro-NIKKOR 70mm f/5; while the range of reproduction ratio works from 1/5X~1/30Xcovering an image area of 64mm x 95.5mm. It doesn't seemed to provide infinity focus as suggestive overall working range is 1,815mm. It has a screw mount (d=72mm p-1mm) & Adapter plate at the outer ring like the APO-NIKKOR series of enlarging lenses (o.d.=98mm). It measures 80mm (D) x 86mm (L), weighs 600g/1.32Ibs).

Nippon Kogaku Japan / Nikon early design Microscope
Nippon Kogaku Japan Macro-NIKKOR lenses. Year introduced/discontinued: No exact info, probably during early '60

The Nippon Kogaku Macro-Nikkor lens series
consist of Macro-Nikkor 1:2.8 f=19mm (white-lined R-Ratio 15X~40X), Macro-Nikkor 1:4.5 f=35mm (
blue-lined R-Ratio 8X~20X), Macro-Nikkor 1:4.5 f=65mm (Yellow-lined R-Ratio 3.5X~10X), Macro-Nikkor 1:6.3 f=120mm (Red-lined R-Ratio 1.2X~4X)

Between '60 ~'70, Nikon already had already established a very mature facilities to supply specialized microscopes for scientific, laboratory, medical studies and other industrial needs. Probably in the field of microscope application, it may never be that easy prior to arrival of reflex-SLR, as convenience of TTL direct viewing provided by a SLR camera provides image viewing and capture process on microscopes can be readily recorded. During the rangefinder era, Nikon did produced a Microflex Kit which enabled a number of their Nikon S-series RF cameras to be used for micrography, as the Nikon Microflex will be covered in another section in this site, but it has many models such as PFM, EFM, AFM, CFM and the concept was extended to the reflex-mount F period. Anyway, Nikon was not the only manufacturer in this field, as microscopes during the corresponding period were mostly using a universal Royal Microscopical Society (RMS) thread. This standard was shared among some of the most respected manufacturers in the microscope business such as Zeiss, Leica, Olympus and Nikon. Although each maker may offer a wide range of objective designs to meet the performance needs of specialized imaging methods but during the period, but the RMS thread was a standard. For microscopes, Nikon had produced a series of lenses called Macro-NIKKOR. which consists of 19/2,8, 35/4,5, 65/4,5, 120/6 where sometimes we referred them as Microscope Nikkors.

Each of these Macro-NIKKOR had been individually optimized for a restricted range of magnifications and marked on lens with its R-ratio working range. The series enable adequately for coverage needs of variable magnification from 1:1~ 40:1 ! Although the Macro-NIKKOR were made as microscope-specific but it can also be mounted on a Nikon reflex camera via bellow/adapter such as BR-15, BR-16 or other combinations. Naturally, they also made adapters to enable other microscope labels to use the Nikkor or the other way round, such as L-F Adapter, enables it to mount any of the RMS lenses on M39 Leica thread mount. This means adapters permits interchangeability among many labels. However, as I am not good at this specific field and don't intend to go further other than by just a rough overview.
NOTE: - For those who may be interested, here are two LINKS, one is to NIKON's Microscope division website and another is a useful article written original by Giorgio Carboni, with translated doc edited by Harry C. Brown "How to with a Microscope". The adapter principle is applicable even today, meaning you can actually mount a Nikon made microscope lens head via adapter to a Nikon AF camera and even used for other camera labels. By the way for photographers who has keen interest into the fascinating world of macro-photography, Nikon has an annual photo contest called "SMALL WORLD" do show your talent or work there okay ?

Macro-NIKKOR 1:2.8 f=19mm (white-lined R-Ratio 15X~40X)

This 19/2.8 Macro-NIKKOR provides the highest magnification ratio among the 4 models shown here. Although it has almost the same small dimension with the shorter focal length series but the maximum aperture has a very bright f/2.8. I am not sure if any of the older NIKON microscopes would provide any form of automatic diaphragm but quite certain they don't as the lens part doesn't has any mechanism caters for such possible function. When it is use with a Bellow unit, it has to be mechanically coupled and setting aperture should be manually. So a brighter f/2.8 lens may provide elevated degree of convenience for a more comfortable viewing during operation and/or examination of details.

This 35/4.5 Macro-NIKKOR shares a very compact design and providing magnification from 8X~20X.

Macro-NIKKOR 1:4.5 f=65mm (Yellow-lined R-Ratio 3.5X~10X) I don't have any images to show this model here but there are two sources where you can take a look how it is like. Peter Braczko's Nikon Hand Book page 10-3, has a photo of the lens shown in black / white but interesting note is, the lens has better and clearer print of lens data at the front ring. The focusing ring on the shown unit used a mix of a grooved scallop-type design with a more modern Nikkor diamond grip pattern like those Nikkor of late '60. Partly, this provide a clue that the Macro-NIKKOR 65mm f/4.5 could be introduced at a much later stage than the others M-Nikkors. The dimension of the lens is not pin-sized anymore, measures almost like the Macro-Nikkor 120mm f/6.3. If you don't intend to buy Peter's excellent book and prefer just to have a quick glimpse to satisfy your curiosity, Japanese collector of these Macro-Nikkor, Michio Akiyama has a picture of the lens mounted on his reflex Nikon F2 Titan.

Nikon Macro-NIKKOR 1:6.3 f=120mm (Red-lined R-Ratio 1.2X~4X) first look this lens could easily mislead you to relate it to a modern red-lined Canon L-series optic, huh ? Wondering whether design of a '60~'70 Nikkor lens had actually "inspired" others, hehe ..regardless, this is a very beautifully crafted Nikkor lens.

A Nippon Kogaku Nikon Macro-NIKKOR 1:6.3 f=120mm (Red-lined R-Ratio 1.2X~4X) with front and rear lens caps
Among the 4 Macro Nikkor, this lens at 120mm has the longest focal length as well as the smallest maximum aperture. Similarly as focal length increases, it provides a modest range of magnification from 1.2X~4X. However, telephotographic focal length does rendering a more natural perspective. On the other hand, as compare to other pin-size Macro-NIKKOR counterparts, the larger dimension makes it looks closer like a normal 35mm lens optic.

You may ask, can any of the two pin-sized Macro-Nikkor 19/2.8, 35mm f/4.5 and the mid-sized Macro-Nikkor 65mm/4.5 and this 120mm f/6.3 be used on a conventional Nikon reflex SLR camera ? Yeap, possible but as the mount are different, it can be first, by coupled them to a Nikon Bellow Device via an adapter such as BR-15, BR-16. Extension ring may still be possible, but Bellow Unit, although more bulky and limits mobility, but provides flexible movement in extension as well as control once it is being setup.
Here is a view by M. Akiyama of his setup comprised of a Macro-NIKKOR 1:6.3 f=120mm mounted on his Nikon F w/Bellow Unit.
Another view presented in his site shown a Macro-NIKKOR 35mm f/4.5 on a Nikon Bellow Unit via BR-4 Adapter Ring (? refer below..).

A Macro Adapter Ring is used to mount a lens in the reverse position on a bellows attachment, it can be on either camera body or with an extension ring. Step-down rings may require to fit individual lens in order to be used on a Bellow Unit. the BR-15 adapter ring works for 39mm screw-mount lenses to a Nikon F-mount body; while BR-16 ring enables any RMS-threaded microscope objectives or enlarging lenses coupled to the BR-15 ring.
