Versatile telephoto zoom is designed for full-frame Sony E-mount mirrorless cameras and can also be used with APS-C models where it will provide a 105-450mm equivalent focal length range. RXD stepping motor unit provides high-speed, high-precision, and exceptionally quiet operation that takes full advantage of in-camera features including Sony's Fast Hybrid AF and Eye AF features plus direct manual focus. 15 elements in 10 groups with one LD (low dispersion) lens element precisely arranged to suppress axial chromatic and other aberrations that are likely to occur with telephoto zoom lenses. Compatible with in-camera shading, chromatic aberration, and distortion lens correction functions. Minimum focusing distance of 31.5" to suit working with close-up subjects. Rounded seven-blade diaphragm contributes to a pleasing bokeh quality. A high-strength aluminum-magnesium alloy and moisture-resistant construction benefits this lens' use in inclement conditions.
