Covering a variety of telephoto focal lengths, this 55-300mm zoom is designed for APS-C format A-mount cameras, where it will provide a far-reaching 82.5-450mm equivalent focal length.
A variable f/4.5-5.6 maximum aperture helps ensure that lens size and weight is kept to a minimum.
One extra-low dispersion glass element is featured in the lens design to help reduce chromatic aberrations and color fringing for improved clarity and color neutrality.
By incorporating a Smooth Autofocus Motor (SAM) unit into the lens itself to drive the focusing element group, this lens is able to deliver smoother, quieter, and faster performance than coupled systems. Also, the design helps to achieve a minimum focus distance of 4.6'.
Rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
