on both bodies I have (IIn and 30d), they are customized to focus with the back button. I did that for sports shooting at the time.
Is focusing with the back button inappropriate for landscapes (specifically - sunrises - which I will shortly be trying for the first time)? Rather, should focus be better achieved with the traditional half-press? I have the wired shutter release cord that will recognize the half press.....
thanks...........
