It puzzles me why Canon won't out a customizable button a little further down. It would things a lot easier...
With Magic Lantern, you could switch keys and put the SET function on AF-ON and vice versa. If you use BBF a lot, SET might be easier to reach, at least on some camera bodies. It's not included in the standard ML distribution, but there are other key swtiching/simulation functions already there and you'd only have to copy/paste the code.
really? didnt know that
can you program the rate button to activate AEB like a 1D does with its button press?
