As dswatson says you can prioritise shooting or focusing. That does the job. I did set my DoF preview button to change SingleShot-AIservo for rapidly changing situations. I did register AF points in all three positions of the camera (Portrait, left right and landscape) and found that I need just to push buttons to jump AF from one end of the screen to the other or to the middle - it is very fast and metering follows well: eg in landscape I registered one AF point at 1/3 to the left, pushed the active point to 1/3 to the right via multicontroller and if I need middle than just depress the multicontroller straight down. So, push AF-ON goes the the left, and depressing the multicontroller juggles between middle and far right or where I left it before. I quite like this shortcut instead of hitting the multicontroller all the time around.
