|Nikkor 18-70mm f 3.5-4.5 - review roundup
news posted on November 21, 2006
|Nikkor AF-S 18-70mm f/3.5-4.5G IF-ED DX is a compact standard zoom lens with a highly practical wide-angle to medium telephoto focal range, good cost performance, and optics optimized for use with Nikon digital SLRs. Optical performance is augmented through the incorporation of 3 ED glass elements and 1 composite aspherical lens that together provide appropriate compensation for aberrations.
By Thom reviewed Nikkor 18-70mm and wrote:
"Sharpness is excellent throughout the range, with f/8 being the point of maximum sharpness on my sample pretty much across the entire focal length range. Even at f/3.5 (or 4.5 at the tele end) in the corners this lens remains an very good performer--much better than you'd expect for the price. I'd be more comfortable about using this lens wide open if it weren't for the vignetting, but if you're a Capture user and shoot NEF, you can safely ignore that comment, as Capture's Vignette control handles this lens perfectly."

SLR Gear reviewed Nikkor 18-70mm and wrote:
"Shot wide open, the 18-70mm does very well across its full focal length range, with even its weakest performance (at 17mm) being better than average. Sharpness is also surprisingly uniform across the entire frame. This lens also has an unusually broad "sweet spot," delivering excellent sharpness across the full focal length range when stopped down one to two f-stops from the maximum aperture at each focal length. As usual, its images get softer when you stop down all the way to the minimum aperture (f/22-f/25, depending on focal length), but even there the 18-70 does quite well, the average blur index rising only to 3, much better than average for such small apertures."

PhotoZone reviewed Nikkor 18-70mm and wrote:
"The Nikkor AF-S 18-70mm f/3.5-4.5G IF-ED DX is a lens with many souls. The lens is capable to deliver very good resolution figures and low CAs but on the other hand distortions as well as vignetting are very pronounced specifically at 18mm. However, most users will rarely use large aperture settings at 18mm so the vignetting problem is usually no show stopper. The build quality of the lens is very decent and the Silent-Wave drive provides a speedy and silent AF. All-in-all the price performance ratio of the Nikkor is very sound."

Press release by Nikon:
Nikon Corporation is pleased to announce the introduction of the AF-S DX Zoom-Nikkor 18-70mm f/3.5-4.5G IF-ED, a compact standard zoom lens with a highly practical wide-angle to medium telephoto focal range, good cost performance, and optics optimized for use with Nikon digital SLRs.
An important addition to the DX Nikkor lens lineup specially designed for Nikon digital SLRs, this convenient zoom lens offers ample 18-70mm zoom performance. Equivalent to a 27-105mm lens in 35mm format, such a focal range comprises the most commonly used focal lengths -- offering maximum versatility that can accommodate anything from tight portraits to expansive scenes. The AF-S DX Zoom-Nikkor 18-70mm f/3.5-4.5G IF-ED also offers easy handling and excellent portability through compact dimensions of a mere Ø73 x 75.5mm (2.9 x 3.0 in.) and a minimized weight of approx. 390g (13.5 oz.) .
Optical performance is augmented through the incorporation of 3 ED glass elements and 1 composite aspherical lens that together provide appropriate compensation for aberrations. A rounded 7-blade diaphragm opening gives out-of-focus background elements a more natural appearance, which can be ideal when shooting tight portraits, for example. And through the adoption of an SWM (Silent Wave Motor), the AF-S DX Zoom-Nikkor 18-70mm f/3.5-4.5G IF-ED enables swift, silent AF (Auto Focus) performance.
AF-S DX Zoom-Nikkor 18-70mm f/3.5-4.5G IF-ED Major Features
- A Nikon DX format exclusive lens covering the most frequently used focal range of 18-70mm (35mm equivalent: 27-105mm/ digital 28-105mm)
- Adoption of an SWM (Silent Wave Motor) enables swift, silent AF (Auto Focus) performance
- A handy focus mode switch enables simple selection between manual-priority AF (Auto Focus) and MF (Manual Focus) operation
- Exceptionally high optical performance designed specifically for use with digital SLRs
-- 3 ED glass elements effectively compensate for magnification and eliminate chromatic aberration for minimized color fringing
-- ED glass and composite aspherical lens elements also compensate for coma, astigmatism, and other forms of aberration
