Try a better way to focus your DSLR! Using back button autofocus is a faster, easier, smarter way to get great AF results from your DSLR. This video will show you how AF modes work - and why decoupling autofocus from your shutter release can take your photography to a whole new level.

This method works both for camera with a dedicated AF-ON button or by reassigning a button on the back of your camera for autofocus.

Questions? See THIS PAGE:

NOTE #1: With newer Nikon cameras, VR activates when you press the Af-On button, with older models, it only activates with a half press of the shutter release.

NOTE #2: In order for this to work properly on a Nikon, you need to have your AF Priority Selection custom function set to "release", not to "focus". That is the default behavior for AF-C, so most won't have an issue. However, if your camera isn't firing when you focus, recompose, and shoot, that's probably why.
