The Ai-S spec Nikkor lenses at 50mm focal length

 


Nikon F3 with three standard 50mm Nikkor lens
The commercial success of the multi-AE modes Minolta XD-7 and followed by Canon's A1 and Minolta XD-7 during the late '70 probably has convinced camera manufacturers on the future direction of automatic SLRs. Old time photographers like Nico, Rick and me probably can recall the confusing state in the market place during first quarter of the '80; each and every major camera manufacturers were busy rolling out their respective models which actually, for the first time, making first time consumers who may be seeking a camera turned off simpler to simple Point & Shoot (P&S) camera models. Against the competitions, one apparent weakness of Nikon was its inability to offer Program AE and, more importantly, Shutter Priority AE during that time. Partly due to Canon aggressive approach in exploring Nikon traditional strong hold among professional users (in particularly, sports shooters) with emphasis on Canon FD advantages in offering Shutter Priority AE.

With the pin-size Nikon EM's companion Series E lenses that began appearing in 1979, observes though not happy with the omission of the traditional meter coupling prong on the lens aperture ring, but they also notice of a new meter coupling ridge being added onto the lenses. Some have already in anticipating of a better things to come in the near future. Although it took longer than expected, but the Program AE enabled Nikon FG (1982) and the first Nikon that truly offered photographers with an all shooting AE modes Nikon FA (1983) have finally completed the cycle (by the way, Nikon FA which won both Japan's Grand Prix and European Camera of the year award in 1984 was more due to an innovative metering system called 5 Segment Metering System - the front runner for today's standard metering mode on virtually all modern SLRs).

However, although the Series E lenses can be regarded as the early version of lenses produced by Nikon which incorporated with an Ai-S specification; the Nikkor lens family also went through a general lens updating program which includes a cam added to the bayonet mount to enable Programmed/Shutter Priority AE control possible with capable Nikon SLR models. Although the lens-spec upgrade was generally aimed for more sophisticated Nikon SLRs to come, but towards the end of 1984, the emergence of interest to autofocus probably has made Nikon switched their development effort on that direction. The change of an Ai-S spec to the Nikkor lenses may seem bring little benefits to the manual focus SLR users (confined to the mentioned Nikon FG, Nikon FA and the last of the manual focus Nikon F301 (N2000) models during mid of the '80; but technically, many of these manual focus Nikkor lenses can permit Nikon photographers enjoy the multi-AE control modes in the autofocus SLRs that were introduced at later years (naturally, they don't autofocus - EXCEPT during the first few years after turning to autofocus, Nikon has
designed an AF-converter, TC-16) to "make" manual focus lenses operate like an autofocus lens.

One good thing remains: on the more expensive MF Nikkor lenses, the Ai-S spec lenses still have the meter coupling prong on the aperture ring, this tiny device still enables the lens to be coupled with the metering system in all those NON-Ai Nikon SLR camera models produced prior to this switch. There is a scoop on the steel rear section of the lens mounting flange, the purpose of it is to detect the focal length of the particular type of Ai-S lens in use, hence, this analogue way just feed to the camera for Programmed AE and Shutter Priority AE to set a higher shutter speed if the lens is longer than 135mm. During the early days, it was termed as intelligent program mode (errrr..). For the users of Ai-S lenses with any Nikon camera models other than those few mentioned, you just use your lenses like any of those Ai-Nikkor and need not have to worry on compatibility. In fact, you can also just use your Ai-Nikkor lenses with the lens aperture stopped down to their respective minimal aperture settings with those (Nikon FG, Nikon FA and F301) and the Program AE & Shutter Priority AE may still work. Lastly, I know many of you may still want to compare qualitative aspect of Ai-S with older Nikkor Ai lenses. Well, you may be right in some ways but frankly, looking back to all these years, I am more than happy when compares it to most autofocus lenses (in particularly those produced late '80 to first quarter of the '90. Further, the lens coatings on Ai-S lenses somehow exhibits a more natural rendition of colours (in particular when deal with human elements like skin tones; while older versions are more accurate or neutral), Although this may not a a decisive factor in affecting a purchase consideration, but overall, personally I quite this series of Nikkor.

Nikon Nikkor 50mm f/1.2s standard lens

This Ai-S version of the Nikkor 50mm f/1.2 was introduced in September, 1981. It is a very well designed lens, and solidly built. The change of a bright orange colour of its minimum aperture both on the aperture ring and ADR (aperture direct readout scales) makes it very easy to differentiate the previous Ai version. .

A lovely picture of the Nikkor Ai-S 50mm f/1.2s lens
It has retained much of the appearance of its predecessor but its outlines are more contour and well defined which projects a modern feel and look in its overall appearance. The rubberized focusing ring has been designed with a wider dimension for easy and positive grip; and more importantly, the lens featured a shorter rotation from closest distance to infinity (as shown with a change in the placement of respective positions of the depth of field scales, which includes the distance scales in metres and feet) - all these improvements made were primarily aimed to improve lens handling for photographers during shooting

Even if currently the market emphasis is centered on autofocusing. But this manual focus Nikkor lens first introduced 20+ years ago is still the fastest lens available in the Nikkor lens group, even today. The lens has a very large diameter. Although it is not intended to be just looked good when mounted onto a Nikon but it does make a setup like that awesome. There are probably many followers on large aperture lenses and many reasons are being, the large aperture provides a bright viewfinder image which makes focusing easy, enjoyable and precise. The eight steps apertures provide a very versatile manipulation of depth of field as well as the shallow depth of field at its largest opening particularly suitable for many applications such as in studio, fashion, portraiture, press, journalism, travel, indoor sports or on location shootings.

Technical highlights:-

* A tremendously versatile lens, offering a natural perspective corresponding to human vision.
* Large maximum aperture of f/1.2 provides an incredibly bright and easy-to-focus images in the viewfinder and allows shooting under adverse lighting conditions.
* Superb image quality - extremely well corrected for coma and spherical aberration.
* Top built quality, great lens handling quality; designed to last, other than shines.
* Great system compatibility with new and old Nikon SLRs EXCEPT for those which use command dial(s) control for aperture settings.
* Despite its larger diameter, it still takes popular 52mm filters or share many of your system filter accessories with other Nikkor lenses
* An ideal fast speed standard lens for candid, travel, fashion, stage, scenic, available-light shooting as well as professional usage.

In relation to possible version history, perhaps the only thing that puzzles me always was the weight of the lens which started from 420g for the Ai version; 380g for the early Ai-S and 360g mentioned in a year 2002 Nikkor lens catalogue. Err .. may be you guys find out for me rather than letting me scratching my head on this matter. But one thing is for sure, unlikely the optical formula being altered. So, I guess may be the changes are more confined to use of materials in various parts. Whatever its is, this is one fast speed Nikkor lens that I wish to be included in my collection as well - only if it comes down in prices. Come to think of it - haven't you notice manual focus Nikkor lenses have always maintained a very good premium over others (inclusive of AF-Nikkor) even if they are in a "used" state ? That is good...

Nikon Nikkor 50mm f/1.4s standard lens

Similarly, the Ai-S version of the Nikkor 50mm f/1.4 also went through a similar lens upgrade to an Ai-S lens specification back in September, 1981and it can also can easily identify with its bright orange colour minimum aperture value in both aperture ring and ADR (aperture direct readout scales). For other lens identification of lens type, refer to the section and suggestive links provided at the top of this page.

My Nikon F4 with an Ai-S  Nikkor 50mm f/1.4s (AIS)
There are probably two existed versions of the Ai-S Nikkor 50mm f/1.4s. More of less they still looks identical. The version that replaced the 1981 lens has a shorter rotation for focusing, this may have been applied to many of the Nikkor after 1984 onwards. Anyway, if that matters to some of you, you can also differentiate the versions with the newer series in the difference from a shorter distance scales from its closest focusing distance @ 0.45m/1.5' to infinity (OO).

Even if it was first debut during the third professional class
Nikon F3 era, the Nikkor 50mm f/1.4s continued to serve Nikon photographers throughout the next generation autofocus Nikon F4 and even the Nikon F5 where there are still demand for this supposedly a standard lense. All these could have made Nikkor standard 50mm f/1.4 one of the most used lenses in all photography !

With a f/1.4 aperture, this relatively fast speed Nikkor standard lens has enjoyed worldwide renown as the "reference" lens for Nikkor lenses where it doubles to act as a reference for Nikon's NIC lens coatings process in colour accuracy and balances for other Nikkor lenses. Of course, on its own the image resolution and optical definition it presents. It may not be having the extra bright f-stop of the f/1.2 counterpart, but it has a better price versus performance ratio. So, overall it makes a better investment if absolute fast speed is not an often used practice in your photography.

Without flash, the lens demonstrates its worth under extremely poor light conditions as well as in available light situations. The relatively large aperture of f/1.4 provides an all-around bright image in the viewfinder which aids the photographer on focusing easy and accurate. At f/1.4, the lens has shallow depth of field, and the displacement of focus resulting from stopping down of the diaphragm is virtually minimized. At full f/1.4 aperture, a slight flare may be detected but at f/2.8 or smaller, the flare completely disappears. This compact, well-designed lens is an outstanding general-purpose lens for portraiture, landscape and indoor sports photography.

Technical highlights:-

* A versatile lens, offering a natural perspective* corresponding to human vision.
* Relatively large maximum aperture of f/1.4, provides an easy-to-focus images in the viewfinder for both focusing and photo composition
* Top class image quality - common optical aberrations such as coma and spherical aberration are well contained by the superior optical design
* Very high built quality - hallmark of all manual focus Nikkor lenses. The lens handling is easy and positive. Aided with various features like wide range of depth of field scales
* Great system compatibility with new and old Nikon SLRs EXCEPT for those which use command dial(s) control for aperture settings.
* Filter attachment size uses 52mm filter accessories - a standard feature of all MF Nikkor from 24mm to 200mm at one stage.
* Multi purpose usage for all round general photography - just treat it as a short medium telephoto or a wideangle with a narrower picture angle will help you open up plenty of photo opportunities

* Although focal length has nothing to do with perspective (camera to subject distance has more to do with that) but due to most frequent use of standard lens is from a moderate shooting distance to infinity, we assume this provides a more natural perspective which is relative in correspondence of a human vision.

Nikon Nikkor 50mm f/1.8s standard lens

Compact, lightweight and affordable, the Nikkor 50mm f/1.8 lens is ideally suited for most general purposes, from scenery, travel and landscape photography to group shots, full-length portraits to even as an excellent alternate lens for close up photography (use in conjunction with a Nikon Bellow unit or via other extension rings). As we have discussed earlier, the 50/f/1.8s was an upgraded lens aimed to replace the Nikkor 50mm f/2.0. However, as the lens could have been delivered to the market at later phase in 1978, Nikon actually did an Ai-update to the old Nikkor 50mm f/2.0 first. The Ai Nikkor 50mm f/1.8 that eventually surfaced which has a marginally faster lens speed was very well received even though it is slightly pricey than the f/2.0 counterpart. Further, when users began to realize its potential for close-up photography, Nikon immediately responded by an upgrade that stops the aperture down to f/22 for expanded depth of field control - critically for close-up photography. The lens has been sold for additional few more years as for some strange reasons, while one expected an Ai-S Nikkor 50mm f/1.8s to be there soon but none.

Ai-S  Nikkor 50mm f/1.8s (AIS) a side illustration of an Ai-S  Nikkor 50mm f/1.8s (AIS)
"....This is standard lens for the manual focus Nikon cameras and is also the inside tip for portraits with camera like the Nikon D200 and D2x that support manual lens metering. On these cameras it becomes and effective 75mm f1.8, perfect for portraits. Whatever you choose to do with it, the lens is one of the sharpest that Nikon has made and has a beautiful machined aluminum feel that has been lost in the AF era...." - Joshua Cohen -

It was not until early 1982 that we finally saw an Ai-S Nikkor 50mm f/1.8 being introduced to the market. The added cam at the rear section and the mechanical groove of the Nikkor 50mm f/1.8s hence, fully couples to both the full aperture metering system and the automatic diaphragm mechanism of all Al-type Nikon and Nikkormat cameras (excludes the CPU type cameras without meter coupling levers some early ones such as the Nikon F50). The metal lens mounting ring is noticeably thinner than earlier Ai version.

Nikon FM2N with Nikkor 50mm f/1.8s
Although we seldom practice it, the lens can still be used with a Tele-Extender such as TC-200 or TC-201s to double its focal length for extended application but remember that using the 50mm f/1.8 at apertures wider than f/1.8 will not result in any gain in speed and could possibly cause a loss in image quality). Another plus is Nikon Integrated Coating (NIC), which applied to lens surfaces to minimize ghost images and flare, and give you sharper, higher-contrast photographs. The lens coating for the Ai-S lenses exhibits a better colour rendition, I think. Due to its versatility and top class build quality, at one stage, this version of the Nikkor 50mm f/1.8s was very much source after by Nikon photographers.

Nikon Nikkor 50mm f/1.8s Mark II standard lens

I remembered it was sometime back in the pre-AF period, Nikon unveiled a pin-sized Nikkor 50mm f/1.8s lens. It has every reasons to make someone believing it is an E-Series 50mm f/1.8s of 1979 except that it came with a Nikkor outfit. Missed from the lens spec is the traditional meter coupling prong on top of the aperture ring and a single row of deeply ridge focusing ring (similarly, the aperture ring has been slimmed down as well). Further, it weighs only 145g despite it still has a similar 6 elements in 5 groups design optically but probably scaled down to thinner elements (hehe..). Look at the comparing photos below here and probably you may understand why everyone is making so much of noises during that time. I guess consumers do have the right to do so..huh ? But Nikon could have been thinking since it was intended to supplement the Nikon F301/N2000 while the previous f/1.8s was still being offered in the Nikkor lens group, why made so much of a fuss ? Well, I guess by 19985, the old one with a better packaging was already phased out and this new update was the only option of a manual focus 50mm f/1.8s for consumers to choose from.

Nikon Nikkor 50mm f/1.8s Mark III standard lens

Well, while consumers are not totally stupid and turned defensive. Hence, when the sales got sluggish, and Nikon was not totally deaf either. So, the introduced revised version has been gone through a few phases in redesigning to improve its weak appearance to ask for a Nikkor premium price tag. The all new Nikkor 50mm f/1.8s with a different facelift (optically remains the same) was brought to the market again later. However, one noticeable difference is its improved closest focusing distance, which comes down to 0.45m (1.5 ft) and this patched the apparent factor of the E-lens converted 50mm f/1.8s MK II mentioned earlier (Nikon 50mm f/1.8s close focuses to 0.6m (2 ft, which is identical to Series E 50mm f/1.8s). So, finally the extra effort made this new 50mm f/1.8s MK III a little different and came out of the shadow of the E-class (not a Metz...though) optic. Another add on by Nikon is:- Added is a lens's mounting assistance post which serves as a convenient feature for mounting the lens in the dark (With the post facing up, simply push the back of the lens against the camera body's lens mounting flange, then twist the lens counterclockwise until it clicks into place).
