Overview and features

Nikon caters particularly well for macro photographers, with 40mm, 60mm, 85mm and 200mm options in addition to this 105mm lens. An update to the popular Nikkor 105mm f/2.8D AF Micro optic, the Nikon AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED adds a host of improvements, chief of which being Nikon's second generation Vibration Reduction (VR) system.

This, a macro first according to Nikon, uses a compensatory lens group that shifts to counter image blur. It promises a four-stop effect when used as close as 3m away from the subject, which drops to three stops when used at a 1:2 reproduction ratio, and two stops when used at 1:1. Nikon does, however, recommend that Vibration Reduction is turned off when using a tripod.

Elsewhere, an internal focusing system enables the lens to constantly maintain the same length, and therefore the same working distance from the subject. This is useful for macro photography in general, but particularly for shooting living subjects such as insects.

Internal focusing also means that the front of the lens stays static as the Nikon AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED focuses, enabling filters and other front-mounted accessories to be used without any hassle.

Focusing itself is carried out by Nikon's Silent Wave Motor technology, which arrives with the same high speed, low noise promises as the similar technology found in its rival lenses. As with similar systems, it also enables the manual focus ring to be used for fine-tuning, once autofocus has been confirmed.

Optically, the lens has 14 elements arranged over 12 groups, with a single ED element among these for the prevention of chromatic aberration.

A nine-bladed diaphragm is said to help produce circular bokeh, and Nano Crystal Coating is also used to help minimise flare and maintain image contrast. This works by gradually changing the angle of refraction as the light enters the lens, which helps more to pass through to the sensor rather than be reflected.

Next to similar macro lenses, such as Canon EF 100 f/2.8 Macro USM, the lens is fairly bulky, but its 62mm filter thread is a reasonable size and means that you won't need to spend a small fortune should you want to invest in a filter or two.

The barrel is finished in the same mottled effect Nikon uses on its DSLRs, and despite being almost entirely plastic on the outside, it feels perfectly solid. A gold ring encircles the front of the barrel, behind which sits a large focusing ring that moves freely enough to be easily operable while not being so slack that it moves out of a set position.

The three switches for focusing, focus limit and Vibration Reduction are all clearly labelled and click satisfactorily into position, while their positioning on the barrel enables each to be conveniently flicked back and forth by the thumb as required.

Performance and verdict

The lens moves quietly enough while focusing, not quite as silently as Sigma's new 105mm EX DG OS HSM macro lens, but not far behind it either. 

More importantly, it focuses swiftly and comfortably to the standard expected from its price tag. When hunting against low-contrast detail, it quickly runs back and forth until focus is found, and when it's found it's confirmed without hesitation.

This will, of course, vary between different camera bodies, because higher end DSLRs will be equipped with superior focusing systems to those further down in the range.

Because the lens isn't particularly small, it's a pity that its focusing window should be. The three lines of information – distance in metres, feet and magnification ratio – are closely bunched up together, and the size of the window provides a poor viewing angle. To see the bottom line, you essentially need to be looking down from directly above the lens, which isn't particularly convenient.

Still, that this minor grievance is the only one worth mentioning should make it clear that there's very little to fault with - and plenty to like about - the Nikon AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED's operation.

At its maximum aperture, the Nikkor lens does a stellar job to record sharp and detailed images, with just a slight drop towards the edges of the frame. When stopped down to around f/8, results are just as impressive, but sadly it can't keep it up for long, and by f/16 diffraction causes its results to fall behind some of its rivals.

Sadly, its control over both distortion and chromatic aberrations, while not bad, is also bettered by even cheaper macro optics.

The Vibration Reduction system is effective, though, not always providing its claimed four-stop advantage but safely having the benefit of a couple of stops.

Verdict

In short, for its wide-mid aperture results, the Nikon AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED's a corker, and with its VR system on board it's a great choice for non-macro work such as portraiture.
