For any T4i users who are not aware yet - http://usa.canon.com/cusa/support/consumer/eos_slr_camera_systems/eos_digital_slr_cameras/eos_rebel_t4i#DriversAndSoftware

what's good about it?

It goes to 11

nope... it goes to 12

GH3 has "12.4 EV". I do not know if this is really true because that black cow in the back looks too black although I raise brightness.
