Autofocus shooting is made possible with SLR models that do not have a built-in motor, such as the D40 series and D60. The AF-S NIKKOR 50mm f/1.4G is a high-performance large-aperture, single-focal- length lens especially suitable for professional and advanced amateurs who use Nikon FX-format cameras such as the D3 and D700, and frequently shoot human subjects as well as night landscapes and astronomy. What's more, when attached to a DX-format SLR, this f/1.4 lens with 75mm equivalent picture angle is capable of shooting portraits with beautiful blur effects.
