Can somebody explain to me HOW lack of a mode dial is a good thing? I've never really understood the button system on the 1D line. To me it seems to be a lot slower to switch modes like this.
That's the point. You don't want the mode changing accidentally and more to the point, the mode doesn't change that often - less often than you change lens/camera.
sometimes it's critical to swap modes ultra quickly though, especially into various C modes and back to
