Part 3:- AF 28-70mm Nikkor zoom lens with Silent Wave Motor and Internal Focus Mechanism and Rare Eartth ED glass

Nikon's AF-S Zoom Nikkor 28-70mm f/2.8D IF-ED wide-telephoto Zoom lens
Year Introduced: Sept., 1998 matte black version; March, 1999 silvery-gray version; Discontinued: Still a current model (As at 08.2007)

In 1998, Nikon had announced a series of immensely successful high power zoom lenses with a starting zoom angle at 28mm. The AF Zoom Nikkor 28-105mm f/3.5~4.5D IF and AF Zoom Nikkor 28-200mm f/3.4~5.6D IF were two good representation of this category of zoom lenses. Along with the earlier Nikon AF Zoom Nikkor 24-120mm f/3.5~5.6D IF (1996) as well as a newly created zoom range of Nikon AF Zoom 28-80mm lens group (1995) which has began slowly replacing the 28-70mm zoom range as Nikon budget entry zoom lens, the AF Zoom Nikkor 28-70mm f/3.5~4.5D had seemingly reached the end of its product cycle. Eventually it was being phased out during late 1999. Amidst these changes within the AF Nikkor lens development program, Nikon had released an AF-S Zoom Nikkor 28-70mm f/2.8D IF-ED where Nikon specifically intended to keep the 28-70mm with only a sole member without any comparing cheaper alternatives. It was officially introduced to the community in Sept. 1998 and in a rather strange move, Nikon also offered an alternate silver-gray colored version for photographers a year later in 1999. Although the zoom lens has no exotic zoom ratio nor an exciting zoom range, but it has proven over time that it has turned into a favorite zoom lens for many Nikon photographers.

The AF-S Zoom-Nikkor ED 28-70mm f/2.8D IF was among a new series of high performance AF Nikkor zoom lens introduced during the third quarter of the '90 which employed a Silent Wave Motor ("SWM") inside the lens to drive the focusing, thus the "S" designation behind the "AF" signifies the use of this renewed AF mechanism. As a result, autofocusing is different from conventional way of camera driven AF, it has been smoother, near silent and almost instantaneous responding to focus.

One of the most appealing element with this new AF-S zoom was the constant aperture of a very practical f/2.8 maximum aperture - where it maintains throughout the entire zoom range. Although f/2.8 was considered to be moderate in many prime lenses, zoom lenses with a far more complex optical composition and with a f/2.8 maximum aperture are generally considered to be "high end" optic. Other than the fast lens speed provides users with a bright and easy to use viewfinder image for focusing and photo composition, it also offers a more important factor for handheld photography in low available light photography as well as providing a wider scope of depth of field control over an image capture process.

As a member of an elite class of AF-Nikkor lenses to serve professionals as well as the serious users group where it can fetch a higher premium over other general consumable products, Nikon had also ensure the lens packs with some of the most advance optical innovations within to showcase their optical and technological development. , Thus, in addition to the AF-S lens configuration, this lens also features a few other important elements such as use of one PGM aspherical and two ED (Extra-low Dispersion) lens elements ensure that images that are sharp, clear as well as compressing color fringing to absolute lowest level. Also, the use of a 9-bladed diaphragm that produces a nearly circular aperture, out-of focus images in front of or behind the subject are rendered as pleasing blurs. Moreover, the lens has an internal focusing (IF) design, so there is no change in the overall length of the lens from infinity to its closest focusing distance of 0.5m (1.6 ft.), contributing to balanced handheld operation.

The AF-S (and/or AF-I lenses) is, it contains a focusing motor built in to the lens (rather than using the auto focus motor built in to the camera body to drive for focusing). This enables faster autofocusing. In the case of the AF-S spec. optic, it operates in a more silent auto focusing than any of the previous Nikkor lenses that use conventional camera driven AF system. Originally, AF-S Nikkor lenses usually are deployed into super telephoto lenses such as the 300mm, 400mm, 500mm and 600mm, or zoom lenses with a fast maximum aperture such as the AF-S Zoom Nikkor 80-200mm f/2.8D IF-ED, 17-35mm as well as this 28-70mm but it is extending its usage on many other new series of AF Nikkor lenses today after these early successful attempts.

Silent Waves Motor

The SWM technology used in Nikons AF-S lenses, work by convert traveling waves into rotational energy to focus the optics. The ultrasonic traveling waves move in a spiral pattern inside the lens barrel. The motor is positioned on top of the waves, and they drive it from below. In principle it is similar to surfing, the waves drive or push the surfer provided he's balanced atop them. This enables high speed auto focusing that's extremely accurate and super quiet. Each AF-S Nikkor lens' Silent Wave Motor interfaces directly with the lenses' focusing elements. Because there is no gear-train, there is none of the power loss or noise associated with conventional gear-type lens driving systems. The lens receives the power for it's internal focusing motor and the focusing instructions from the camera body and therefore can only be used with suitable cameras. This partly explained why the AF-S series is only being recommended to be used with a selective of older Nikon SLR camera models. Note: There is no power consumption during manual focusing.
Illustration for Asherical lens element
The Aspheric lens element offers lens designers to compress optical issue in a high performance zoom lens design with problems such as coma and other types of lens aberration. They are particularly useful in correcting the distortion in wideangle lenses. In addition, use of aspherical lenses contributes to a lighter and smaller lens design. There are a few types of popular methods in merging aspherical lens element in a typical optical lens, namely:- the most time-consuming is the precision-ground aspherical lens elements which requires extremely rigorous production standards. Hybrid lenses are made of a special plastic molded onto optical glass and shape to exacting standards of spherical correction. Molded glass aspherical lenses are manufactured by molding a unique type of optical glass using a special metal die technique.

"ED" in its lens specification is referred to the special glass developed by Nikon which has a specific optical property that corrects chromatic aberrations. Lenses with ED incorporated in their optical structure usually has a distinctive characteristic when dealing with some colors spectrum. It helps to deliver sharper images with very neutral color rendition. Lastly, "IF" is explained as the use of Internal Focus" in the lens optical structure where the optical train in the lens actually moves internally, this makes the lens comes with no physical extension during zooming or during focusing. Another advantage is, it may help to drive focusing faster and has better power efficiency. Lastly, as the front attachment doesn't rotates, it facilitates use of special filer accessories with instant visual inside finder without the hassle of verifying the effect after the desired focus is achieved.


NOTE: This lens offers Silent Wave ("SWM") autofocusing with Nikon F6, Nikon F5, F4-Series, F100, F90X-Series/N90s / F90-Series/N90, F70-Series/N70, Pronea 600i/6i and Pronea S cameras. Similarly, beginning from Nikon D1X, other subsequent Nikon Digital SLR cameras such as D100, D70, D2 Series and D200 etc. that followed (which includes other labels such as Kodak DCS 420/520 series onwards as well as Fuji S1/S2 Pro onwards) may also be compatible. But I am not sure if the various Nikon E-series Digital Still SLR models are usable or not.

Many people regard the AF-S Nikkor zoom 28-70mm f/2.8D IF-ED as a classic zoom lens. Prior to availability of other lenses with a higher zoom ratio (such as the AF Zoom Nikkor 24-85mm f/2.8~f/4.0D IF (2000) and/or the AF-S Zoom Nikkor 24-85mm f/3.5~4.5G (2002) IF-ED with a higher 3.5X zoom ratio), together with the AF-S Zoom Nikkor 17-35mm f/2.8D ED-IF with a spectacular ultrawide picture angles range, along with the 28/70, both served as a natural extension and companion zoom to another classic telephoto zoom AF-S Zoom Nikkor 80-200mm f/2.8D IF-ED. In comparison, although both of these Nikkor zoom shares a common element in fast speed, but the moderate picture angles of the AF-S 28/70mm zoom has more reason to act as an easier to use zoom range over the 17/35mm which is one of the main reason why makes it so popular among the Nikon system users.

Physically, the AF-S zoom lens has a slightly varied design in a few areas such as the grip pattern which is from those traditional AF-D zoom lenses as the M/A function provides in an AF-S zoom lens enables manual override during autofocusing which makes manual focusing ring wider than non AF-S lenses. Physically, this lens is extremely well made as well as offering exceptional lens handling properties. Most of the non-operational areas in the lens barrel was coated with a crinkle finish and projects a very rugged professional feel and look. The maximum aperture of f/2.8 which remains constant throughout the entire zoom range is its main asset for low light photography as it ranks among the best in a zoom for its light gathering power. Despite the use of aspherical lens element, the internal optical train consists of a rather massive 15 elements in 11 groups design and along with the very high grade of physical built quality, making this moderate wideangle / short telephoto zoom lens weighs near a kilo at 935g (33 oz.).

This favorite of many Nikon photographers has a distance window scales with 28mm and 35mm infra index marked. The rotation angle of the zoom ring for various settings are quite wide apart. The manual focusing ring is generously wide and effortless to operate With the M/A switch at the side panel for the photographer to turn ON or OFF. Both the front and rear exposed lens elements are quite large. The rear lens mount has more electronic contacts than conventional AF-D lenses. The lens mount is a solid metal piece and with all the encoders and levers which technically makes it a native Ai-S lens. However, due to the physical nature, the AF-S lens still permits to be used with older manual focus Nikon bodies. Neither the AF Nikon other than those specific below will provide autofocus (But focus assist is possible). Meaning to say, this AF-S zoom lens only serves newer series of Nikon autofocus SLR models as even the older Nikon AF bodies will revert back to manual focus only. The front filter does not rotate and for those who always think this is important, the lens offers a non rotational filter attachment. The lens also uses a 9-blades diaphragm and aim to offer out of focus elements more natural. Both to me are not particularly important but serve as an added advantage, that is all. Well, it is the speed and performance that counts for justification. Both barrel distortion and vignetting is well compressed with contrast maintains high throughout across the entire zoom range. Color density and rendition of skin tone is neutral but accurate. Personally, this lens exhibits the kind of performance that can make you feel the extra premium is justified. Prior to a week use with my Nikon F5, the combination was not the best and most comfortable you can expect as it is very heavy but it is not as bad as compare to the F5/80-200mm. I guess most pros and serious users could have used to these kind of setup and probably this is the reason why the solid and power pack built-in Nikon F5 is now reverted back to the modular design in the Nikon F6. This permits photographers to determine their own setup prior to an assignment. Similarly, although generally DSLRs consumes more power but the Nikon D1/D2 Series should also have the same provision for a modular design.

Whatever it is, I am very pleased with the performance offers with this AF-S Zoom Nikkor 28-70mm f/2.8D ED-IF. Large aperture lenses also have the advantage for handheld available light photography. The combined weight of the setup I had tried - although heavy but it adds a good , stable and balancing effect to survive a drop in shutter speed while light level is not ideal for handheld to approx. 1/8 sec. The zoom rotational force is a little on the stiff side but still fall within the just about right level. The manual focus ring is more easier to handle as compared and even during manual priority during AF. Both the exposed front and rear lens elements are quite a diameter and care should always be when performing lens interchange. Within the wide/telephoto zoom lens group, despite it has been around for a while and with some other alternatives which provides a wider zoom ratio such as the Nikon AF-S Zoom Nikkor 17-35mm f/2.8D IF-ED, AF Zoom Nikkor 18-35mm f/3.5-4.5D IF-ED, AF Zoom Nikkor 24-85mm f/2.8-4D IF, AF-S VR Zoom Nikkor 24-120mm f/3.5-5.6G IF-ED, AF Zoom-Nikkor 28-200mm f/3.5-5.6G IF-ED etc., the AF-S Zoom Nikkor 28-70mm f/2.8D ED-IF stands out along the with the AF Zoom Nikkor 35-70mm f/2.8D MACRO as few of the time honor AF Nikkor classic. I guess even with such good offering, how it is going to benefit the photographer may depends individually. The strongest asset of the lens is with its large, constant aperture of f/2.8 where you can have low shooting capability as well as a wider depth of field control. A probable under utilized feature of the lens is with its very usable MACRO function where the reproduction ratio delivers an impressive 1:13 maximum @28mm (1:8.6 at normal focusing) as well as 1:5.6 maximum at 70mm at MACRO mode. Other secondary features such as non-rotational front filter attachment may offer some convenience during shooting with special accessories as well as special filters.

Perhaps Nikon had also realized its commercial potential and thus, the AF-S Zoom Nikkor 28-70mm f/2.8D IF-ED packs many of the prevailing, advance optical/technological innovations within for you to unleash full potential of a Nikon/Nikkor combination. It offers as an excellent zoom lens for a wide scope of shooting applications such as news, sports, journalism, nature, scenic, outdoor or studio portraiture and other personal photography - be it for ambient/available light photography or with a flash. I have many friends who own this fabulous designed/made AF-S Nikkor. Most don't regret their investment except for a few digital users where the conversion as a 42-105mm zoom lens in a DX format may seem a little odd to them - short for the wideangle section. Overall, except for many of the older system users who may not be able to take full advantage of the SWM-powered autofocus (as it may revert the older Nikon back to manual focus operation), similarly - on a less significant note, this AF-S zoom is NOT compatible with most of the Nikon AF Teleconverters), but when it is couples with a compatible Nikon - this can still be regarded as another modern AF Nikkor classic.

UPDATE
: Nikon had released a new AF-S 24-70mm f/2.8G ED-IF in July, 2007 which seemingly looked like an extension to this AF-S 28-70 zoom for Nikon bodies which doesn't require on-lens aperture ring to control aperture. For a wider system compatibility, the AF-S 28-70mm still command a place within the new offering(s). Both of the fast speed zoom lenses are fall under the luxurious class of "standard zoom" category for pros as well as the financial capable group of photographers.

Manual Focus

# Autofocus with manual override Set the focus mode switch to M/A. Autofocus is provided, but you can manually override the focus by operating the separate manual focus ring while lightly depressing the shutter release button or the AF start (AF-ON) button on the camera body of cameras so equipped. To cancel manual override, remove your finger from the shutter release button or the AF start button.

Macro Focusing Normal focusing extends from infinity to 0.7m (approx. 2.3 ft.). Macro focusing is available at any zoom setting (28 to 70mm) down to 0.5m (approx. 1.6 ft.). A maximum reproduction ratio of approx. 1:13 is obtained at the 28mm setting, while a reproduction ratio of 1:5.6 is possible at 70mm.

Focusing, Zooming and Depth of Field In the M/A (autofocus with manual override) mode, first turn the zoom ring until the desired composition is framed in the viewfinder before autofocusing. In the M (manual focus) mode, focusing is possible at any focal length, but the longer the focal length, the larger the image and the shallower the depth of field, making focusing easier. If your camera has a depth of field preview (stop-down) button or lever, depth of field can be observed while looking through the camera viewfinder. Note: Due to the optical characteristics of this lens, when shooting at 1.4m (4.6 ft.) or closer the focal length changes slightly during zooming. Therefore, focus again after zooming when the camera's focus mode selector is set to other than C (Continuous Servo AF).



Nikon had followed Canon's EF-L Series by offering an alternate silvery gray color for the AF-S 28/70mm f/2.8D IF-ED zoom lens. Looks good but lacks Nikon own identity as a an optical product. It helps to project impression of more white lenses around the sporting arenas and news event. From a marketing point of view, it is a stupid move.

Infrared Compensation When shooting black and white infrared film, it is necessary to make slight manual compensation to the focused distance. With color infrared film, no compensation in focus is needed. The two small white dots just to the left of the distance index line are the infrared compensation indexes for 28mm and 50mm. To make the necessary
compensation, focus manually on the subject, then realign your focused distance with the appropriate white dot. Then attach a red (R60) filter for infrared photography. To determine the position of the infrared compensation index at all focal lengths, use this chart as a guide:

Zoom setting

Compensation from distance index line (on distance scale)

28mm

3.0mm (white dot)

35mm

2.2mm

50mm

1.3mm (white dot)

70mm

0.8mm



Minimum
Aperture Lock (Fig. 2) For programmed auto or shutter-priority auto exposure shooting, use the minimum aperture lock lever to lock the lens aperture at f/22. 1. Set the lens to its minimum aperture (f/22) by aligning it with the aperture index. 2. Slide the lock lever toward the aperture ring, so the white dot on the lever aligns with the orange dot. To release the lock, slide the lever in the opposite direction.
