Introduction:- The Nikon AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED was officially released by Nikon during the PMA show in 2003. It replaced the 7 years old original version of the AF Zoom-Nikkor 24-120mm f/3.5-5.6D IF (refer to previous chapter). Between the period of new and old, plenty of changes were occurred in the industry. Notably, there were two significant happenings at Nikon which could had changed the perspective in the market place during this period. Firstly, Nikon has adopted a Sub-Command Dial system on their newer series of SLR cameras for aperture control. The SCD was a feature first introduced with the Nikon F5 in 1996 - it has transformed/altered conventional way how to control aperture as well as shooting habit of Nikon photographers as a whole. The next important change was the emergence of a new generation of Nikkor ultrasonic motors lenses in the AF Nikkor lens group. The incorporation of micro-motor within the lens technically has enabled Nikon to improve their autofocus system as well as the lens handling properties considerably in a very different manner as compare to previously. Commercially, the micro-motor enabled AF Nikkor lenses had also catapulted Nikon back in contention with other most advance autofocus system available in the market. On the other hand, the on-camera Sub-Command Dial offers an entirely different operational sequence as compared to previous days to control the required aperture settings on lens.

Although both of these changes were not exactly an original Nikon innovation* but Nikon has seemingly perfected other's methods and fine-tailored them to fit for use in their own system. Other supplementary functions that came along with these changes, such as VR (Vibration Reduction) as well as extensive use of aspherical lens elements and other rare-earth glass-types with renewed lens multi-coating process have also contributed to a new generation of AF Nikkor lenses. In particularly, the AF Nikkor zoom lens group probably had benefited the most from these, which had resulted in a new series of exciting AF Nikkor Zoom lenses with different configurations appearing during this era. But as a whole, it was not exaggerating to quote modern Nikon photographers are now probably enjoying a level of incredibly widest in selections of lens choice, with an elevated level of shooting convenience never before imagined possible back in those older MF and/or early AF days. The AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED can be easily regarded as a good representation of how things had changed in Nikon shortly before and after the millennium.

* NOTE:- The Sub-Command Dial system was first successfully used in a manual focus Canon T90 in 1986. The concept of ultrasonic motor (USM) lenses were originated by Canon for their EOS/EF system during the third quarter of the '80. The first model which enjoyed the use of USM lenses was the Canon EOS 650 (1987).

To begin with, the zoom range of 24-120mm with an exciting 5X zoom ratio was uniquely a very original Nikon effort. It is very similar to some classic focal length created by in their MF Nikkor lenses such as Nikkor 6mm, 8mm, 16mm Fisheyes, 15mm/18mm ultrawide, 105mm telephotos, 50-300mm or the 80-200mm Nikkor zoom etc. The basic specification of this zoom is very appealing to consumers. Currently, the focal range of 24-120mm zoom is still only available from Nikon. Partly, this was one reason why it was so well received when it was released back in 1996 because, other than the very practical zoom range it provides, it was also quite an innovative idea with such an interesting zoom range. Somehow, the lens has indirectly helped to project an impression of "Nikon is back.." kind of thought because for so long, Nikon had lagged behind others in a few areas until the key reversal with the arrival of Nikon F5 where the AF-D Nikkor lens system was built around with. Exciting as it may be, but strangely, the original effort of the 24/120mm did raised in a fairly wide dividing opinion among Nikon users over certain issues. Other than serving Nikon photographers with an affordable, practical, portable high-power zoom lens with latest prevailing lens technologies within; the release of this AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED may also carry certain marketing objective to revert the negative impression generated on the previous original attempt. To the majority of Nikon photographers, the most significant change in this lens update was actually being designed by Nikon as a G-spec Nikkor zoom lens where the lens does not has a conventional aperture ring. This makes the zoom lens a SCDial-specific lens for newer series of Nikon bodies only which means this lens may has a backward system compatibility issue. Technically, its manual focusing performance is compatible with every other Nikon SLR made since 1959 but as there is no way to control depth of field (due to lack of an aperture control on the lens section) so, it is practically useless to make such a claim (For manual focus Nikon users, you may just forget about this, just go back for the previous AF Zoom-Nikkor 24-120mm f/3.5-5.6D IF version for better system compatibility). Basically, the two primary features of AF-S and VR in this lens update may create some other technical restrictions among many older Nikon SLR models. Below is a rough guide of system compatibility of this AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED with the various Nikon bodies introduced thus far:

IMPORTANT: -Compatible Nikon SLR camera models with the AF-S (applicable to the AF-I) Series AF Nikkor lenses: -
Nikon D2 series, D1 series, D200, D10,0 D80, D70S, D70, D50, D40X, D40, Nikon F6, F5, F4, F100, F90X series/F90 series, F80 series, F70D, F65x, Pronea 600i/S. Note:- Not sure if the three ill-fated Nikon E-series Digital SLR models are belonged to this category too.

With the following AF Nikon SLR models, the AF will be reverting back to Manual Focus only:
Nikon
F60QD, F50QD, F-801 series, F-601, F-501, F-401 series. The old Nikon F3AF is not possible at all as when the CPU lens, AF-S AF-I teleconverter, or, AF teleconverter TC-16AS, is installed in F3AF of the AF finder DX-1 attachment, electric current to flow even with when the main switch of F3AF TURNS OFF, because the electric battery inside AF finder DX-1 consumes, you cannot use with this combination.

In relation to VR compatibility with a Nikon SLR camera models (VR function fully enabled):- Nikon D2 series, Original D1; (D1X/H); (D200, D100, D80, D70S, D70, D50, D40X, D40 etc.); Film based models Nikon F6, F5, F100, F80 series or other possible models in the future.



Nikon's autofocus AF-S Zoom Nikkor 24-120mm f/3.5~5.6D IF-ED wideangle-telephoto zoom lens
Year introduced: February, 2003; Discontinued: Current model (as of 06.2007)

While omitting the various incompatibility issues, the G-Spec 24-120mm Nikkor zoom lens offers its advantage of a very useful 5x high-power zoom range from an ultra-wide of 24mm to medium 120mm telephoto range. It is a native AF-S Nikkor zoom lens with a VR (Vibration Reduction) mechanism built-in. The optical design features two ED (Extra-low Dispersion) glass and two aspherical lens elements to enhance its optical performance. The lens has retained an Internal Focusing (IF) design as used previously in the predecessor, and provided with an additional M/A mode for rapid switching between autofocus and manual focus operation. This G-type Nikkor zoom lens is designed with no aperture rings; with a compatible Nikon body, it offers an advantage of an easier to operate, mistake-free operation because the aperture does not need to be set to minimum (The process of certain shooting AE modes in a electronic Nikon that require an AF Nikkor lens to be stopped down to minimum aperture is eliminated). The zoom range looks as if the lens was specifically designed for film based SLR because when installing the zoom lens to the digital single-lens reflex camera, the corresponding focal length/angle of view will become like a 36~180mm zoom after the format conversion (the wide/tele range of 84° (24mm) - 20° 30' (120mm) will be converted as 61° (36mm) ~13°20' (180mm) for Nikon DX format digital single-lens reflex cameras and for IX240 format cameras, the angle of view will even be reduced further down to 71°~16°20'. I had my first taste of it while testing the lens with a new film based Nikon F6 during its pre-launch and I am using my brief experience as a basis to create this site.

Nikon F6 with AF-S VR Nikkor 24-120mm f/3.5~5.6G ED-IF zoom lens
Major Features

1) High-power 5x zoom lens with focal range starting at 24mm and extends to 120mm telephoto for greater range of picture coverage
2) SWM for a more responsive, quiet auto focusing
3) VR system offers the equivalent of using a shutter speed 3 stops faster (at 120mm), making handheld photography viable when shooting in low light with this built-in shake reduction system
4) A new optical system featuring two ED glass elements and two aspherical lenses to minimize chromatic aberration and improve its optical performance
5) A rounded 7 blades diaphragm makes out-of-focus elements appear more natural
6) A M/A mode for rapid switching between autofocus and manual focus operation
7) Internal Focusing (IF) design for smoother and faster autofocusing as well as improve lens handling
8) Nikon Super Integrated Coating (SIC) offers superb color reproduction while minimizing ghosting and flare
9) G-type lens with no aperture ring (set aperture on camera body); A supplied flower-shaped Lens Hood HB-25 which helps to reduce stray light

Other than the 5X zoom ratio, among other few worthy lens features that deserve attention are the on-lens SWM (Silent Wave Motor) which uses an ultrasonic vibration force driving the lens, making this AF-S zoom lens quicker and quieter during autofocus than previous AF-D version that uses conventional DC motor coupling drive system. A side benefit that came along with the AF-S specific lens is, it also enables a M/A mode that offers rapid switching between AF/MF or even permits users simply performs manual focus adjustment during autofocusing. The built-in VR system is designed to offset the main weakness of the 24/120 Nikkor zoom with the lack of effective lens speed due to adoption of a floating apertures of f/3.5~5.6. The VR system used in this 24/120mm has a lens-shift mechanism which has voice coil motor which is slightly different from the original Nikon VR 80-400mm super zoom as it has a shorter focal lengths. Theoretically, it offers a lab performance of an equivalent 3 f-stops compensation for shake reduction for handheld photography. This has patched the usability issue of the zoom lens in low light shootings. On the other hand, the revised optical system in this AF-S VR zoom lens which comprised of a new 15E/13G with 2X ED and 2X Aspherical lens elements in its optical composition was designed to enhance the overall optical quality. Other side enhancements includes use of a newer SIC lens coating developed by Nikon etc.

I guess probably it is not entirely a very popular decision for Nikon to design this AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED in a G-spec zoom lens but the underlying fact, it is still AF-D native zoom lens but only may post some operational issues with older Nikon bodies. I wouldn't categorized it as an updated version of the previous model but rather as a different breed of a new AF Nikkor zoom lens which shares only the same zoom range which catered for newer series of Nikon SLR cameras which uses the Sub-Command Dial to control apertures. We do know in general situations, camera shake is part of the life during handheld shooting, the Nikon's designed VR mechanism within the lens detects motion using internal sensors and the built-in mechanism in the lens automatically makes the necessary adjustment to minimize the effects of camera shake (but please take note:- this is different from a out of focus scenario but that part of the problem is taken care by the built-in autofocus system). To me, the built-in VR function is a more practical feature than the comparing SWM feature, as generally, this is still a wide-telephoto zoom with a so-so lens speed, the slight speed boost provided by the SWM may not be as important as compared. However, this SWM-spec zoom lens does offers advantages such as a quieter, more accurate AF operation as well enabling easy, swift switching for fine manual focus should I need it without the camera set be to manual focus prior reverting to manual focus.

I would conclude Nikon had paid a lot of attention in ensuring this AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED stands up as a worthy consideration for consumers. The lens packs with many of the latest prevailing Nikon optical and technological innovations within. The IF system that used on the previous AF-D version has been retained in this AF-S VR model, it adjusts the focusing internally and minimizes any possible aberration fluctuation, the torque for lens drive is hence, smoother in this manner which technically makes autofocusing faster too. Further, as the focusing is done internally, the external filter thread does not rotates which enables use of special front attachment accessories without additional operational step after focus is achieved.

Comparing model of the AF-D IF 24-120mm zoom Comparing model of the AF-S VR ED-IF 24-120mm G-sepc zoom lens


The dimension of the AF-SVR 24/120 measures approx. 77mm dia. x 94mm (3.0 in. dia. x 3.7 in.) and weighs approx. 575g (20.3 oz.). The original AF-D version
measures approx. 79mm dia. x 80mm (3.14") and weighs lighter in comparison at 550g (19.6 oz). Nikon claimed they had successfully designed the lens smaller than the predecessor but the figures doesn't suggest it is so. However, due to removal of the aperture ring, the lens does looks sleeker in appearance and easily can be differentiate from the original version as the older version has a mushroom shape lens tube.

  The lens barrel uses an industrial grade crinkle finishes resin coating, when combines with other desirable elements in the lens design, all these help in a way to generate the overall high quality, rigid feel.

With a compatible Nikon SLR camera body, the AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED is a great zoom lens to use. It has decent built, optical quality with excellent lens handling properties. Both the zoom ring and manual focusing rings are separated and using a non-slip hard rubberized multi-rows covered pattern. When you get used of it, you can easily distinguish the two respective rings with their corresponding purposes. The zoom ring operates slightly stiff as I think it was purposely designed to avoid accidental shift of zoom setting. The manual focus ring has a slightly more positive turn and a firmer grip than all those older AF Nikkor zoom lenses. Although the hand grip pattern is a little too shallow but the widen dimension makes MF control very comfortable and I'd still rated this as an improvement. The rubberized grip of the zoom ring on this AF-S zoom lens uses a newer design, it has a simple and long ridge pattern which actually resembles Canon's EF lens design but it is quite easy to hold and changing the focal lengths/zoom positions. The most frequently referred focal lengths of 24mm, 28mm, 35mm, 50mm, 70mm, 85mm and 120mm are marked circularly around the zoom ring. The zoom ring's rotation from the widest 24mm to the 120mm at the longest end is actually a very short stroke, possibly it was designed to improve responsiveness to alter focal length in the shortest possible timing. Since the AF-S zoom has brought back extra benefit of manual focus control via the M/A mode during autofocusing, the manual focus ring has been redesigned in the most generous fashion (In fact, it is now even wider than the zoom ring). But sometimes when you think of it, this is still essentially an autofocus zoom, the proportion of usage of zooming control is usually higher than manual focus, so - the width of the grip should be reverse huh ? Another good lens design with this AF-S VR 24/120 is, this AF-S VR 24/120mm Nikkor zoom has been reinstalled with a distance scale window again. It is placed nearer to the photographer rather than on the outer end of the lens tube and provides a more logical and functional way in this placement.

For a zoom lens that has such a slow opening/floating aperture, the overall dimension of this AF Nikkor zoom lens is considered to be quite large. The 72mm filter attachment size of this AF-S VR zoom (same with the previous AF-D model) may not be the same of the 77mm diameter as found on some of the high end models but an advantage is, filter accessories for 72mm are easily/readily available/accessible everywhere and generally, they are also more cheaper. Nikon supplied a flower shape HB-25 lens hood as standard accessory. Due to its wide zoom ratio, it is not deeply recessed and I think the dedicated lens hood is more effective for wideangle settings rather than for tele-range usage.

A major difference of this AF-S VR zoom from the previous AF-D IF predecessor is, the front filter doesn't rotate when you zoom or focus but merely extends physically. The AF-D IF version does rotates but in a lesser degree during zooming but the front filter stays stationary during focusing. This improves the use of special attachment or filters an easier task as you need not have to readjust the attachment anymore.

M/A mode switch and VR control for AF-S VR 24/120mm zoom lens   At the side of the lens, there is a protruding plate where the VR control and M/A mode switch locate. The top control slide switch is for M/A mode and manual.

When set your preferences to autofocusing, just leave the setting to M/A where you can control and adjust focus even when you are operating in autofocusing, basically, this is where the AF-S series of lenses excel over the previous AF-D series. Located just below the M/A control switch is the VR control. You can decide to turn on or goes without it.

Optically, the AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED is a revised design. The optical train within comprises of a VR unit placed at approx. center among the optical groups (but it has no effect with the optical performance and only serves its purpose for vibration reduction. The VR function can be turned off). The glass content has been increased in both number and glass type where a new 15 elements in 13 groups design (from the previous 15E/11G) with an addition of two ED (Extra-low Dispersion) elements, along with two aspherical elements (refer below for the illustration). The lens elements used are said to be lead and arsenic free. The use of ED glass in a short tele lens is considered to be generous as usually, chromatic aberration is not as pronounced at shorter focal lengths but the addition does helped to maintain its overall sharpness and color fidelity. Use of aspherical lenses in its design is aimed to suppress various possible aberrations such as spherical aberration where the curved spherical surface has been improved to plane surface. The use of aspherical lens elements could also has its effect in controlling the distortion esp. coma which is generally common towards wide angle settings in such a high power zoom lens type (esp. with use of larger aperture). Although the close focus capability is not measured up to true macro performance as offered by the famed Micro-Nikkor lens group but it offers a commendable performance with closest focusing distance approx. 0.5m (1.6') which yields a maximum magnification ratio of approx. 1:4.7 - a handy and commendable feature when you need it most. Good things is, it works on all focal length and it is especially useful when you are shooting at the longer end of the telephoto range where a more natural perspective is achieved for close-up photography.

Unlike the previous AF-D version, where we believe most of the late units had been treated with Nikon's exclusive SIC lens coating but the AF-S VR Zoom-Nikkor 24-120mm has been treated with the latest SIC process. Basically, lens coatings can change the reflectivity of the surface or suppress specific colors, and the technology behind these coatings has improved enormously in the last ten years. The Nikon Super Integrated Coating, or (SIC) delivers an even better color balance, clearer images with greater control over flare and ghost especially when shooting pictures during backlit situation. Although it doesn't totally eliminates such an optical effect but it does helped to trim the undesirable effect to negligible level. Together with the use of ED glass, images taken with the AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED has seemingly delivered a sharper and higher contrast images than the previous AF-D model (in particularly focal lengths near the telephoto range).

You probably have read some of the good things mentioned but the AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED does has a few features being omitted by Nikon. Firstly, the infrared focus index has strangely being eliminated from the features list. Next - although most Nikon folks had probably accepted the stupid fact where a depth of field visual reference guide is not important anymore but there is no luck for a possible revival for such a feature where I thought Nikon should has taken the debut of AF-S series to reinstalled this lovely feature again.

Personally, I guess the main issue that truly relates to this AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED is the system incompatibility that makes this lovely zoom lens not be able to extend its appeal to wider audience within the Nikon user community.

Minus expectation of this very affordable AF-S VR power zoom measuring up to challenge other top rated optics, this is still a very usable zoom lens for general photography with an extensive and practical picture angles. The main drawback in its overall design is still centered with the slow lens speed provides. Although the VR mechanism installed within has it neutralizes for handheld photography in low available light but the negative aspect in its native form still exist where it projects a dimly lit finder image as well as limited range of depth of field control.

Within the updated AF Nikkor lens group - the hybrid system Nikon users group may think replication of an equivalent 36-180mm focal lengths is not entirely an exciting figure for them at all. Well, it is such a pity that the huge pool of established Nikon film based users cannot take full advantage of this delivery of the improved version of the 24/120. Frankly, from a commercial point of view, probably it doesn't benefit too much for Nikon either as it has a smaller scope of market users to tab onto. However, as AF-S and VR feature has a very different operational sequence/configuration from those previous DC motor drive AF Nikkor lenses. Seemingly this is the main problem in creating the system backward incompatibility with older Nikon bodies. Please take note the incompatibility also extends to older teleconverters but since the startup lens speed is so bloody slow (f/3.5 to f/5.6), it certainly requires some wisdom trying to explore such a potential combination for focal length extension as the effective lens speed will drop down to almost in-usable range. For previous owner of the AF-D IF model, it probably may also need some justification to jump for this upgrade. Further, as within the AF Nikkor lens group there are also other newer and good alternatives which may be more viable and practical as a single lens for Nikon (esp. for both effective lens speed and extended DOF control). So, to further narrow down the limited series of Nikon SLR cameras that has Sub-Command dial to change aperture on camera and owners that still may not had a wide-tele zoom lens in their lens system yet can be an indication to its possible salable figures - despite it is being rated as a far improved model from the predecessor. But for those who starts up their photography with a compatible Nikon and wish to find a good, practical and quality wide-tele zoom lens, this AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED can be a little gem for their general photography.
