Sony's SELP28135G is a powered zoom lens from Sony that has been created to satisfy professional optical and operational requirements for both high-quality still and movie imagery, including 4K, when matched with a full-frame format camera such as the a7S or a Super 35 format camcorder such as the PXW-FS7.

The Precision G-series optical designed lens offers minimized angle of view variation (breathing) while focusing and no focus shifting (axial displacement) while zooming.

This lens also offers 3x manual rings for superior control: zoom, focus, iris and a constant F4 max aperture maintains exposure / depth of field.
