Nikon has announced a new lens, the AF-S NIKKOR 50mm f/1.8G, which should be welcome news for users of entry level Nikon DSLRs like the D40, D40x, D60, D3000, D3100, D5000 and the still-to-be-shipped D5100.
The AF-S designation is what matters because “S” there means the new lens has built-in Silent Wave Motor which enables the lens to autofocus on entry level Nikons.
Nikon said the new 50mm f/1.8 lens construction consists of seven elements in six groups, with one aspherical lens element to reduce instances of chromatic aberration, even when shooting wide open. A rounded diaphragm opening combined with a 7-blade aperture contributes to a substantially more circular bokeh for a more natural appearance of out-of-focus background elements.
The new lens will start selling in June for about $220, MSRP.
