ImageReasonFocus, Depth of Field, and Macro
What autofocus configuration should I start testing?
Enter your subject's movement, size in frame, and obstruction risk to get a generic acquisition, area, and switch-sensitivity brief to test against your camera's menu.

Match settings to movement, size, and obstruction
Autofocus settings become useful only when they match the subject's movement, size, and likelihood of being blocked by other objects. A broad area can help track a large predictable subject, while a small area can stop the camera from jumping to a background. This is a starting configuration brief, not a substitute for the camera's documentation or a live test.
A still small subject with one critical plane calls for a precise acquisition area and confirmation before release. A continuously moving subject with frequent obstructions may need continuous acquisition, a controlled zone, and slower switching so the system does not jump to an obstacle. Test a burst with the real background and inspect the critical feature, because subject contrast and camera behaviour determine the final result.
This is a planning calculation, not a certification. Confirm the relevant camera, lens, card, printer, contract, location, or workflow constraint in the real setup before relying on the result.
Make one controlled test with the important variable held constant. Inspect the subject detail, motion, highlights, and intended output, then adjust the setting that protects the priority you named.
FAQ
- Which brand AF mode should I select?
- Camera labels differ. This tool gives generic behaviour to match against the documented mode descriptions in your camera.
- Is this a guarantee?
- No. The result is bounded by the inputs and assumptions shown on the page. It is designed to support a better next decision, not replace a test, measurement, proof, or professional judgement where one is needed.
