Optimized for FX-format D-SLR cameras but equally at home on any Nikon DX-format D-SLR, this updated classic with a fast maximum aperture is ideal for everyday shooting, perfect in low lighting situations and great for producing images with beautiful background blur (bokeh). The AF-S 50mm f/1.8G includes Silent Wave Motor technology (SWM) for fast and precise autofocus, M/A Focus Mode Switch for seamless changes between manual and autofocus operation and an aspherical lens element for outstanding optical performance with high contrast. Nikon's Super Integrated Coating enhances light transmission efficiency and offers superior color consistency and reduced lens flare. A significant innovation in AF lens technology, Nikon's Silent Wave Motor uses ultrasonic (inaudible) vibrations rather than a gear system to focus the lens, providing incredibly smooth, silent and precise autofocus operation.
