Back button focus made easy
How to set up back button focus on your camera
01 Find the Custom Function
Example for a Canon EOS 5D Mark II
(for other makes and models check your manual). Press the Menu button and use the Main Dial to highlight the Custom Functions. Use the Quick Control dial to highlight C.Fn IV: Operation/Others, and press Set.
02 Activate the back button
This will open Custom Function 1: Shutter Button/AF-ON Button. To activate back-button focusing, you need to select option 3: AE lock/Metering+AF Start. To do this, press Set, then use the Quick Control dial to scroll to option 3 and press Set again.
03 And shoot!
Press the Menu button twice to clear the LCD. With this option selected, you can use the AF-ON button to activate autofocus and take a meter reading, and the shutter button to release the shutter. It takes a bit
of practice, but it works a treat!
