Nikon AF-S Nikkor 24-85mm f/3.5-4.5G ED VR

A standard zoom for FX format DSLRs covering wide angle to telephoto focal lengths without the size, weight or cost of f/2.8 equivalents. This lens costs around £520 and includes Nikon's second generation VR system and silent focusing with full time manual focus override. Can it really compete for quality with Nikon's professional lenses? We'll find out in this review.

Nikon AF-S Nikkor 24-85mm f/3.5-4.5G ED VR Handling and features

Weighing 465g and being only 78mm long, this lens is quite compact and lightweight for an FX format lens. As a result it is a perfect companion for the Nikon D700 used for testing, even without the MB-D10 grip attached. As is the case with Nikon's other high-end consumer lenses, high quality plastics have been used for much of the lens' construction and a rubber gasket surrounds the metal lens mount, to help prevent the ingress of dust and moisture into the camera body.

A silent wave motor powers autofocus, and speeds are good, with the lens locking onto a subject quickly and precisely. The narrow focusing ring is located close to the camera body and its action is well damped and smooth, which makes fine adjustments quite easy to apply. The zoom action is also smooth and has quite a short throw. A quarter turn bring you from wide angle to telephoto, which helps with adjusting composition quickly. The zoom doesn't creep forward when pointed downwards as just enough resistance has been applied to the mechanism to prevent this.

Closest focus distance is 38cm, and focusing is performed internally, so the 72mm filter thread does not rotate, which should make this lens ideal for use with graduated filters and polarisers.

Nikon's second generation Vibration Reduction system promises to allow hand held shooting at shutter speeds up to four stops slower than the usual rule of thumb for sharp hand-held photos. With care, sharp shots can be taken at 85mm and 1/10sec around half the time, which is roughly three stops slower than the usual rule of thumb for sharp hand held images would allow. The VR system has very little lag, stabilising the image in the viewfinder in a fraction of a second.

Nikon AF-S Nikkor 24-85mm f/3.5-4.5G ED VR Performance

At 24mm and maximum aperture, sharpness in the centre of the frame is already excellent, with the clarity towards the edges of the frame not too far behind. Stopping the aperture down improves sharpness with peak quality being achieved at f/5.6 for this focal length. Here clarity in the centre is outstanding and excellent towards the edges of the frame.

Zooming to 50mm results in a drop in overall clarity, but sharpness in the centre is still very good in the centre of the frame at maximum aperture. Clarity towards the edges of the frame falls just below good levels at this setting. Peak quality across the frame is achieved with the aperture stopped down to between f/8 and f/11 where sharpness in the centre is excellent and very good sharpness is present towards the edges of the frame.

Zooming to 85mm sees a slight increases in sharpness towards the edges of the frame, with good levels of clarity being recorded during testing. Sharpness in the centre of the frame remains very good at maximum aperture and peak quality across the frame is achieved at f/11.

How to read our charts

The blue column represents readings from the centre of the picture frame at the various apertures and the green is from the edges. Averaging them out gives the red weighted column.

The scale on the left side is an indication of actual image resolution. The taller the column, the better the lens performance. Simple.

For this review, the lens was tested on a Nikon D700 using Imatest.

Chromatic aberrations are well controlled throughout the zoom range barely exceeding half a pixel width between 24mm and 50mm. There is a slight increase in fringing at 85mm, but CA levels of 0.75 pixel widths should not pose any issues for general photography.

How to read our charts

Chromatic aberration is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software.

Apochromatic lenses have special lens elements (aspheric, extra-low dispersion etc) to minimize the problem, hence they usually cost more.

For this review, the lens was tested on a Nikon D700 using Imatest.

Falloff of illumination towards the corners of the frame is quite pronounced for a lens sporting a moderate maximum aperture. At 24mm the corners are 2.83 stops darker than the image centre and at 85mm the corners are 1.93 stops darker. Visually uniform illumination isn't achieved until the lens is stopped down to f/8 or beyond throughout the zoom range.

Distortion is also quite strong at the extremes of the zoom range. At 24mm 4.74% barrel distortion is present and this is replaced with 2.78% pincushion at 85mm. Both these distortion values can be quite visible in images with straight lines towards the edges of the frame. Luckily the distortion pattern is uniform across the frame throughout the zoom range, which should make applying corrections relatively straightforward in image editing software afterwards.

A particularly deep petal shaped hood is provided with this lens, which does an excellent job of shielding the lens from extraneous light that may cause flare or loss of contrast. This lens is pretty resistant to flare, although some flare may appear when shooting into the light at 24mm, and a slight loss of contrast can be seen at 85mm under the same conditions.

Value for Money

This 24-85mm lens costs around £520, has a maximum aperture of f/3.5-4.5, VRII and internal, silent focusing with full time manual override. The price and compact size should make this lens the ideal choice for those looking for a quality lens, who don't require a constant f/2.8 aperture, or the build quality and resulting weight of a professional lens.

By comparison, Nikon's high-end 24-70mm lens is more bulky, has a weather sealed build, lacks VR and costs around £1300. However it does have a constant f/2.8 maximum aperture. Their 24-120mm is slightly longer at the telephoto end and is also more bulky as a result. However it sports a constant maximum aperture of f/4, otherwise it is similarly specified and costs around £830.

Third-party manufacturers tend to only offer lenses with a constant f/2.8 maximum aperture in this focal range. Sigma's 24-70mm f/2.8 EX DG IF HSM costs around £600 and includes silent, internal focusing with full time manual focus override but lacks stabilisation. Tamron's 24-70mm f/2.8 is similarly specified of the Sigma, except it includes stabilisation and costs around £995. Finally, Tamron's 28-75mm f/2.8 is the most basic lens of these. It lacks silent focusing and stabilisation, but is available for around £350.

Nikon AF-S Nikkor 24-85mm f/3.5-4.5G ED VR Verdict

This new 24-85mm lens is ideal for those looking for a high quality standard zoom for a Nikon FX format DSLR, especially if the cost and bulk of other lenses on offer is off-putting.

It is capable of delivering sharp images with low CA, and although distortion is quite strong, it should be easily correctable in image editing software afterwards. The addition of Nikon's VRII stabilisation should help when shooting at low shutter speeds in low light too.

The Nikon AF-S Nikkor 24-85mm f/3.5-4.5G ED VR is a high quality standard zoom lens.

Distortion & falloff, is it really so hard to design a lens without this nasty habits? Sad I don't care about software fix because it s.... up the sharpness...

Could really have done with a continuous aperture, and a couple of stops wider would have been nice too!

That lens already exists... it's Nikon's 24-70mm f/2.8. Wink
