The EOS-RT was my last (for many years) SLR. I seem to recall a number of tests supporting the short lag time and my own experience would confirm it. I would think the times are reasonable give that all that has to happen is for current to either flow (or stop flowing depending on the circuit design) to a solenoid to release the shutter as soon as the button switch is closed. This should probably always be faster than the reaction in a mechanical linkage which requires some form of linkage and pawls working against tension in the shutter to accomplish the release. Also with a mechanical shutter some resistance has to be built in to avoid accidental triggering. If anyone has doubts about this take a look at the adjustable trigger mechanism on a top of the line match pistol or rifle. They can be set so that the just resting the finger on the trigger trips it. Now there is a an idea for LEICA...add a hair trigger adjustment to the new MP and charge another $500 for the feature. I also think test might show that the Hexar AF when set to manual focus (using hyperfocal settings) and manual mode for shutter and aperture may have the the shortest lag of all.
