Additional interesting information I gleaned from the RG article that wasn't on the official Canon praise release:
- AF sensitivity is now down to -2EV, like the Olympus flagship, 1 stop better than all the previous Canon & Nikon pro cams.
- in-cam CA correction corrects both lateral *AND* axial chromatic aberration, so they maybe 4 years late with in-cam CA correction compared to the Nikon DSLRs, but at least they improved upon it by correcting both ways. I don't know if there is even software that corrects for axial CA now? Not updated on that.
- the new dual multi-controller mini-joysticks; the QCD apparently has a touchpad within the center for fine correction.
- reflex mirror blackout time is now just 60ms down from 80ms, no mention if the shutter release lag time has also been lowered.
