Oh, yea,
I also use Cf12 (Mirror Lockup) all the time. I wish it had a dedicated button. So to speed things up, I use Cf11 to 1, which will keep the menu to the last one used, even if powered off.
So when I want to enable mirror LU, I press menu and it's already on the CF item and it's on the CF12 (MLU), press set, jog the dial, press set, then half press shutter. It takes longer to read about than actually do.
I still wish MLU had it's own button, or maybe a fourth option with the shooting mode (ONE SHOT, CONTINUOUS, TIMER, MLU).
