Autofocus, английский
- Autofocus. the lens is focused automatically by means of the camera’s hardware and firmware, to obtain optimum sharpness of an image.
- The camera lens focuses automatically, usually when the shutter release is half-pressed.
- The ability of the camera and lens to keep the subject in focus during an exposure. autofocus can be continuous, meaning focus is maintained regardless of where it moves within the frame, or single, meaning the point of focus is locked regardless of where the subject may move. for more on this subject, see the explora article, “how focus works.”
- A method of focusing where focusing distances are set automatically. in 35mm slrs, a passive phase detection system that compares contrast and edge of subjects within the confines of the autofocus brackets in the viewfinder and automatically sets focusing distance on the lens. autofocusing motors may be in the camera body or the lens itself. active ir (infrared) autofocusing systems may also be in 35mm slrs in the form of beams in dedicated autofocus flash units, or, in a few models, built into the camera itself. commonly found in amateur lens/shutter cameras. these beams are emitted from the camera or flash, bounce off the subject, then return and set focusing range.
