holding AF on half-drepress?

[silsrf]

Is there a setting where I can half-depress the shutter release while capturing the focus in the center square and then move the frame holding that focus area? It seems if I half-depress for focus and then move the frame, the focus just resets to whatever area is in the center?

TIA

Put the focus mode to AF-S (single) instead of AF-C (continuous).

Not sure what camera you are using, but try looking into lock-on af.

You can focus on an object, press a button and then the camera will track that object and stay on focus (within reasonable bounds).
