Lens NIKON 50mm f/1.4D AF, chính hãng

The AF-Nikkor 50mm 1:1.4D is Nikon's current version of their fast 'standard' prime lens, and while this specific model was introduced in 1995, the basic optical design dates back to the manual focus 50mm 1:1.4 AI of 1977. It features a traditional layout of 7 elements in 6 groups utilizing spherical surfaces only, which Nikon claims will deliver distortion-free images with superb resolution and colour accuracy, plus high contrast even at maximum aperture. The 50mm focal length classes it as a 'standard' lens on the FX format, with none of the 'perspective distortion' characteristic of wideangle or telephoto lenses, whilst on the vastly more popular and widespread DX format it behaves like a short telephoto, ideal for portraiture.

The 50mm 1:1.4 is one of the older lenses in Nikon's lineup, and this is reflected in several aspects of its design. The lens features a traditional aperture ring, which will no doubt be appreciated by photographers who grew up with mechanical manual-focus 35mm SLRs such as the FM range (although the only DSLRs on which it can actually be used are the high-end D1-D3 and D100-D700 bodies); however autofocus is 'screw-drive' from the camera body, and therefore won't work on the entry-level D40, D40x and D60.

Like the Canon EF 50mm F1.4 USM which we've recently reviewed, the Nikon 50mm 1:1.4D commands a hefty price premium over its little brother in the range, the AF-Nikkor 50mm 1:1.8D. It's also up against stiff competition in the shape of the impressive new Sigma 50mm F1.4 EX DG HSM and the Carl Zeiss Planar 50mm F1.4 T*, although both of these lenses are considerably more expensive, and the Zeiss is manual focus only. So what does the Nikkor have to offer in this day and age?
