Focus Lock
A camera feature allowing focus to be locked on a subject before recomposing the frame, ensuring sharpness during composition. Typically activated via half-pressing the shutter or dedicated AF-L button.
Fujifilm Implementation
- Fujifilm cameras utilize Single Autofocus (AF-S) for static subjects, with focus lock achieved through half-press shutter or AF-L button.
- AF-C mode requires AF-L button for focus lock without recomposition (less common for static subjects).
- The Fujifilm Autofocus Setup Guide: Modes, Features, and Optimization details optimization of AF-S for focus lock and recomposition workflow.
