Power Zoom is a lens feature where you can use the physical controls (usually a rocker switch) on the lens body or camera in order to electronically zoom in and out the lens in a smooth and controlled way. Without a power zoom, rotating the zoom ring manually with hand generally introduces shake to the footage and it is hard to achieve a constant zooming speed.
Sony recently introduced two E-mount lenses for its mirrorless camera systems, the Sony E 10-20mm F4 PZ G with the APS-C sensor coverage and Sony FE PZ 16-35mm F4 G with Full-frame coverage to increase its number of lenses with power zoom to six. 4 of these lenses are designed to cover APS-C sensors and 2 for Full-Frame. Below is the list of Sony lenses that features power zooms:
