Nikon has announced its new wide aperture fixed-focal length Nikkor lens, the AF-S Nikkor 50mm f.1.4G.

As its name would suggest, the new lens has a maximum aperture of f/1.4 which will help create good background blur with shallow depth of field.

It also incorporates Nikon's ultra-compact Silent Wave Motor (SWM) ring-type which Nikon says will make for "silent, fast and accurate focusing" and also enables autofocus in cameras without a built-in motor, like the D40 and D60 DSLRs.

The AF-S Nikkor 50mm f/1.4G has two focus modes, M/A (manual-priority autofocus) and M (manual focus), and when mounted on a DX-format SLR, the picture angle is equivalent to a focal length of around 75mm in 35mm format.

Included with the lens will be snap-on front and back lens caps, bayonet hood HB-47 and a flexible lens pouch.

The AF-S Nikkor 50mm f/1.4G will be available in December for £279.99.
