Sony FE C 16-35 mm T3.1

The  FE C 16-35mm T3.1 G E-Mount Lens from Sony features a constant T3.1 aperture with consistent performance throughout its 16 to 35mm zoom range and provides high-quality imagery in low-light conditions. You can operate the zoom manually or use the detachable servo unit to help create dramatic fast or slow zooms with ease. It can also be controlled by a compatible camera's handle or an optional external grip zoom. The lens's constant T3.1 maximum aperture throughout the zoom range means consistent exposure as you change focal lengths in a scene, so you don't have to re-light just to get enough exposure when zooming in.
