Most keen photographers use, or at least know about, back button focusing. For Canon EOS mirrorless cameras, such as the R6 Mark III, this is when you set the AF-ON button at the back of the camera to control focusing, instead of focusing being handled when you half-press the shutter button. With this custom setup, you can press the ‘back button’ with your right thumb to track focus on moving subjects such as soccer players, or lock focus part of a scene, leaving the shutter button for only taking photos (and metering).
But there are lots of other ways to customize other buttons on your camera to make your photographic life easier, and so you don’t miss that shot as you’re fiddling about with your camera’s menus, scrolling for that special setting you can’t find!
