With outstanding NIKKOR optics and an ultra-fast f/1.4 maximum aperture, the AF NIKKOR 50mm f/1.4D delivers superb resolution and color reproduction and a classic 50mm angle of view. Its manual aperture control ring enables smooth adjustments during Live View shooting. Fast enough for shooting in just about any light, it's an ideal walk-around (multi-purpose) lens for photography and HD video recording. Nothing quite isolates and captures the subject of a portrait like a lens that is capable of achieving spectacular background blur (bokeh). When you need to isolate your subject from its background - whether shooting stills or HD videos - the AF NIKKOR 50mm f/1.4D renders a beautiful, natural background blur at its wider aperture settings. Manual control of that aperture means you can make smooth adjustments, even during Live View shooting.
