How Does Canon Auto Focus Work?
I was just thinking, and I realised I actually have no idea how auto focus
works on my Canon DSLR. No infrared. Anyone know how it works?

Canon DSLR's dont have autofocus. When people talk about AF on a canon it means "Almost Focussed" or "Approximate Focus". Actually when the poor design considerations of canon's AF system are taken into account, it's quite remarkable they do as well as they do. Probably most startling is that they use no feedback to ensure that the lens actually did move to the correct focus position. Another oddity is that they don't even try to focus the image, but just try to get the lens within a DOF field range based on an 8x10 print.

Does that mean the AF in consumer-level cameras do not get fooled shooting behind a window anymore? Or does it still get confused sometimes.

It depends on how dirty the window is, and where the lens is focused to begin with. -- Måns Rullgård
