Back Button focussing on EOS 5D Mark III

[J R Mohan]

Tried back button metering and focus set up as per manual but it reverts back to the old setting of half press shutter button. Obviously I am not doing it right.

Can you please guide me the correct way of doing it.

Thanks

Jai.

Just checking which button are you pressing the AF-on or the one with a star *.

You need to define a rear button (or two, in my case) to do AF and the shutter button not to (I use it for AE lock).
