AF: Auto-Focus

AF Full Form

AF full form stands for Auto-Focus. An autofocus optical system uses a control system, a sensor, and a motor to automatically or manually focus on a selected location or area.

The electronic range finder has a display instead of a motor. The adjustment of the optical system must be done manually up to the indicator.

Brief Explanation

Autofocus systems rely on one or more sensors to determine the correct focus. Some AF systems rely on a single sensor, while others use a range of sensors. Most modern SLR camera lenses use optical sensors, which have a separate light sensor that measures light, although later measurements can be made to prioritize the area in which they are located.

Example

A common example of shared use is the autofocus system for phase detection used in single-lens reflex cameras since 1985. Autofocus, which identifies the passive phase, requires some contrast for the work, making it difficult to use in low-light landscapes or even surfaces.

Modes Of AF

  • Active AF
  • Passive AF
  • Hybrid variants
