I've just begun trying out the micro adjustment and it can really do wonders. I've tested a Minolta 24-105mm that was really soft and not it's spot on! I have one doubt though, I've set the MA to +15 on the Minolta and I thought that this would be stored in the camera specifically to this particular lens, but whenever I put in another lens the +15 MF stays. Is this correct? Shouldn't there be a way to store a different profile for each lens?
