Could someone provide the steps required to configure my 50D for back button focusing? I've not been able to set it up correctly.

Thanks

Since the 50D has an AF ON button, all that is required is to remove focusing from the shutter button.

Menu

Orange Camera Tab

C.F.IV:Operation/Others

1 Shutter button/AF-ON button

3:Metering start/Meter+AF start.

This way when you press the AF-ON button the camera will focus the same as a half press on the shutter button.

A half press on the shutter button only starts metering.

If you want to use the * instead of AF-ON for your back button focus

Menu

Orange Camera Tab

C.F.IV:Operation/Others

2 AF-ON/AE lock button switch

1:Enable
* is your AF-ON button and AF-ON button is your exposure lock

0:Disable
* is your exposure lock and AF-ON is your focus start

Personally I shoot a lot in AI Servo and don't want to have to continually hold the back button, so I leave AF start on my shutter button, but, configure my AF-ON button as AF-OFF. This way I start focus with the shutter button, but, can stop it at anytime with a back button press. I find this is works better for me.

To configure your camera like that

Menu

Orange Camera Tab

C.F.IV:Operation/Others

1 Shutter button/AF-ON button

1: Metering + AF start/AF stop

Menu

Orange Camera Tab

C.F.IV:Operation/Others

2 AF-ON/AE lock button switch

0:Disable
* is your exposure lock and AF-ON is your focus stop/suspend

Thanks!!!
