@RogerAs you report live-view AF to be more precise, i.e. with less variation to it, I wonder what your data is on contrast- versus phase-based AF cameras--anecdotal and statistical. Do you get less complaints from four-thirds users than from dslr users? Did you do any experiments on 4/3's lens focussing? Are there any general "truths" to be gleaned on the difference between the systems?
