Additionally, balancing the optics, the zoom also features a Hyper Sonic Motor, which provides quick, smooth, and quiet autofocus performance with full-time manual focus override.

All-in-one zoom is designed for APS-C-format Sony A-mount cameras and provides a 27-375mm equivalent focal length range.

One Special Low Dispersion (SLD) element is featured in the optical design and helps to reduce color fringing and chromatic aberrations for improved clarity and color accuracy.

Three aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering.

Super Multi-Layer Coating has been applied to individual elements to minimize flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions.

Hyper Sonic Motor (HSM), along with an internal focusing design, realizes quick and quiet autofocus performance as well as full-time manual focus override.

Minimum focusing distance of 1.1' and a 1:2.9 maximum magnification ratio benefits working with close-up subjects.

Constructed using a Thermally Stable Composite (TSC) material for greater precision and use in wide temperature variations. Additionally, a brass bayonet affords improved mounting accuracy and rigidity.

The rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
