Precise autofocus and smooth control A 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 APD element Foreground Focal plane Background bokeh bokeh Point source Out-of-focus Out-of-focus Light intensity distribution Intensity decreases towards periphery Optical apodization delivers refined bokeh An 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.
