Hmm.. that will sure help, cos it would bring the shutter n aperture balance out.. however, i do suggest you can try to switch to Manual to have a look at your focus pt using bracketing to see if the shutter n apeture of ur choice is well balanced out if not adjust it till it balance then switch back to aperture to see if the shutter n aperture is well balanced out.. dun be afraid to use manual, after all this is a DSLR, nt a pns
I will give it a try the next time round.
