High resolution and frame rates, remote setups, and handheld shooting have made autofocus and stabilisation ever more important for videographers, and Sony has jointly optimised the designs of lenses and cameras to meet their demands. See the advantages of using Sony’s E-mount lenses in the video.
The combination of Sony's E-mount lenses and cameras assures the best autofocus performance even when shooting in 4K 120p with shallow depth of field, where a subtle defocus is very noticeable. Sony's E-mount lenses incorporate focus actuators with high thrust efficiency, to be uniquely responsive to camera AF commands with exceptionally high precision and speed.
Achieving accurate and creative manual focus control is easy with Linear Response MF. Unlike conventional lenses with electronic focus control, where the focus changes with rotational speed, Linear Response MF changes focus position linearly with the rotation angle. This enables direct and intentional manual focus control, for repeatable operation and precision.
AF Assist allows a new shooting style combining autofocus and manual focus, ideal for videographers. With this feature, manual focus can be seamlessly activated for intentional focus operation while rotating the focus ring even when shooting in autofocus. Unlike touch operation, AF Assist enables videographers to shift the focus without interruption while shooting.
Sony's latest cameras feature in-body optical image stabilisation, enhanced with Active Mode, allowing stable handheld shooting without extra equipment. The combination of lenses and cameras, both designed in-house by Sony, provides exceptional image stabilisation performance.
Sony’s E-mount lenses take care of iris control to meet professional demands. On selected lenses, the aperture click switch allows aperture ring stop to be disengaged as desired. The combination of aperture ring and aperture click switch allows for seamless, silent, non-stop iris control at the lens side.
