you would, had you installed the Canon software
With the Canon software you can ELECTRONICALLY MANUALLY FOCUS from your PC, remote, with the Mirror UP using you scrollwheel or your arrow buttons, or click on arrow buttons on-screen.
Or you can take an AF by lowering the mirror, momentarily pausing LiveView, take AF (only with CENTER AF POINT) and then bring LiveView back on.
When you manually electronically focus 'from distance' no 'signal' is given when focuslock is achieved, as it is NOT AF'ing with the AF system, the mirror stays UP, you just make the focussystem work. Like a car with semi-automatic, you do not have to clutch, but you determine when and where the shifting gear takes place.
The Breezebrowser software (DSLR Remote Pro version 1.5RC1) has this same ability, but ADDS CONTRAST-DETECT AF, that works WITH THE MIRROR UP so when you 'AutoFocus' the camera will start hunting to find the best contrast in the square that is also used to indicate the place where the zoomed view works, you can drag this square all over the place, to zoom in AND/OR take AutoFocus of anything. The ContrastDetect AutoFocus reminded me of my G3, it is about as fast... but works... and locked *IS* sharp!
...€0.02 for now, I am still testing
Kindest regards!
