AF Area, by Lens

The extent of AF area available for each lens is as follows.

The following information applies to lenses with a “variable” area.

  • With the AF area set to [Whole area AF]: approx. 100% (H) × 100% (V)
  • With the AF area set to an option other than [Whole area AF]: approx. 100% (H) × 100% (V) when subjects are detected; otherwise approx. 90% (H) × 100% (V)
  • When using the focus guide (manual focus): approx. 100% (H) × 100% (V) when subjects are detected; otherwise approx. 90% (H) × 100% (V)
