Canon DSLR Sensor Output Overview

Automatic AF Calibration | Manual AF Adjustment | Sensor Output

Testing your AF Sensors

The Sensor Output tab allows you to inspect the raw data from each AF sensor. This diagnostic view reveals physical dust contamination that blocks focus, verifies that the AF unit is perfectly aligned with the focusing screen, and confirms that all sensors are functioning correctly.

AF Sensor Troubleshooting

The AF Sensor tab is a dedicated diagnostic tool used to inspect autofocus sensors or encounter calibration failures. It displays live data readouts directly from the camera's sensor array, allowing you to instantly visually verify that individual sensors are active and working correctly.
