The optical design including a new apodization (APD) element and 11-blade aperture deliver breathtakingly soft, smooth bokeh that ideally sets off in-focus subjects without peripheral highlight distortion due to vignetting, while high G Master resolution is maintained right out to the image edges. Up to 0.25x magnification enables stunning close-ups.Precise autofocus and smooth controlA DDSSM (Direct Drive SSM) focus drive system provides fast, precise, quiet autofocus for stills and movies, while built-in Optical SteadyShot image stabilization makes it possible to achieve maximum subject sharpness at lower shutter speeds. Other features include an aperture ring, switchable aperture ring click stops, a focus hold button, an AF/MF select switch, a wide focus ring, and a dust and moisture resistant design*. *Not guaranteed to be 100% dust and moisture proof.Optical apodization delivers refined bokehAn APD element is similar to a neutral density filter that gradually increases in density towards the perimeter with a correspondingly graduated decrease in light transmission. Its effect is that areas both in front of and behind the plane of focus transition into uniquely soft bokeh.
