Yeah I'm just not sure what's going on... logically it shouldn't make a difference. But for some reason I feel like I'm "hitting the mark" more with the single button for focus and shutter.
What advantage is there to BBF - as far as I have seen it is advantageous as I can either tap focus then compose the shot, release the shutter or be able to hold the button to continuously track. However - till now my learnings have seemed to indicate I'm always going to be using continuous focus, partocularly on birds. So why do I bother with dealing with an extra button (Honest question).
