easiest MLU for 1Ds3 ??
MLU in my menu provides quickest access. You cannot dedicate a button for this action in custom functions. Its a pity because it would be simple to programme and add to the many other custom functions. My D3's have MLU on the shooting mode dial, but it can't combine self timer and MLU, which is just as bad as Canon not enabling a customised dedicated button.
However, I prefer the Canon setup and find it intuitive in day to day use.
