Does the 30D have a 'silent mode'? ...where it's possible to take photographs without the usual indication beeps, shutter noises, etc., happening? (Google mentions the 40D having the silent feature.) I ask, because I have a 'friend' (a somewhat notible member of a local Flickr group..) who I suspect is taking sneak photos of of my female friends from behind, bending over, upskirts beneath the table, etc. I've told him to fscking stop it, but he carries on like I'm overreacting. There's photos he's uploaded that I know were taken surreptitiously (hands folded over the camera.. pinky finger suspiciously near to the shutter button..) yet I didn't notice any indication from the camera a photo was being taken. Yes, it's about time to get heavy on him about it. :/
