I recently purchased a battery grip from my 5D mkiii and I'm a bit puzzled.

I use back button focusing all the time and I thought the buttons on the battery grip were supposed to operate the same way as on the camera body.

But with the grip switched on, back button focus doesn't work.

Any ideas?

Thanks in advance.

Are your sure you switch the battery grip on?

I have a Vello version of the 5DIII grip and the back button focus works as it should.

 Make sure the grip is turned on.

Do you have a Canon version. It might be a defective copy. I have the one by Canon and have had no problem (knock on wood).
