“The shutter won't fire if the camera doesn't lock focus, there's a huge risk that an important shot will be missed. Wedding and portrait photographer Gary Small says he sets up his cameras to “disconnect” the focusing from the shutter release button because he can’t miss the first time around when it comes to photographing weddings and other events. If you’re fussing with camera settings in front of a subject, you’re less engaged and more likely to miss an opportunity,” he says. However the camera now feels more personalized, and the AF settings are more intuitive which is important not just for sports.
Overall it’s a set up for fast performance. “I keep the camera’s AF set to AF-ON only, and start that way for most assignments.

We spoke with three professional photographers-who specialize in different types of photography: sports, wedding and wildlife-to find out why they use the AF-ON button for focusing.Ĭommercial sports and action photographer Jay Watson explains that once he got used to using AF-ON only for focusing he found it to be advantageous for shooting both moving and static subjects. The default setting on Nikon DSLR cameras sets Shutter/AF-ON in which both the shutter-release button and the AF-ON button can be used to initiate autofocus or you can choose to set the AF-ON button only for focus, which means only the shutter-release button will only activate the shutter (snap the picture) when pressed. This technique is also called back button focus. To set the camera to use the AF-ON button for focusing, you will need to set a custom function, which can be found in custom settings, under Autofocus. For the purpose of focusing a DSLR camera, pressing the AF-ON button has the same effect as pressing the shutter-release button halfway.
