The Nikkor AF-S 50mm f/1.4G was announced in September 2008 as the company’s flagship standard prime lens. It shares the same bright f1.4 aperture and standard focal length as the much older AF 50mm f/1.4D, but features an SWM focusing motor, which means it’ll autofocus quickly and quietly on all Nikon DSLRs, including the D40, D40x and D60 models.
It’s compatible with full-frame models like the D700 and D3(x), on which it’ll deliver standard coverage. Mounted on a DX-format body like the D60 or D90, its field is reduced by 1.5 times to deliver an equivalent of 75mm, which is a perfect short-telephoto length for portraits. The fast maximum aperture of f1.4 is also ideal for achieving shallow depth-of-field effects and working in low light. To put this in perspective, an f1.4 lens will gather 16 times more light than one at f5.6, such as the standard Nikkor DX 18-55mm kit lens when zoomed-in.
