SUMMARY
Photographers can significantly enhance their workflow on Canon EOS mirrorless cameras by customizing buttons. The star (*) button, often unused for AE lock, can be reassigned to instantly switch between full-frame and 1.6x crop modes, effectively extending lens reach without changing lenses. This customization is particularly useful for action photography, saving editing time by reducing the need for post-capture cropping. Beyond crop modes, the star button can also be programmed to toggle AF modes (One-Shot to Servo), activate Eye Control AF, switch to Action Priority AF, turn off the screen to save battery, or access White Balance settings.
