When I got my 20D, one of the first things I did was turn off the focus confirmation beep. Then, I found I was getting a troubling number of out of focus shots. I worried about all of the focus issues I've read about here. But last night I decided to turn the beep back on and I realized how often the camera failed to lock focus for a legitimate reason (low light, low contrast, repetitive pattern, etc.). With the beep turned on the camera correctly told me so by not beeping. I realized that I may not have been noticing when the focus confirmation light might have been blinking to notify me of inability to focus... I'm going to leave the beep on for a while (even though I usually hate those kinds of beeps). Just wonder, who leaves the beep on?
I have it off but have been considering turning it on. I hate gadget beeps also but have noticed focus not locking a few times. I have enough things to look at without watching for the little green light to come on all the time... Maybe I'll get used to looking for it now that I'm aware of it but I have such a hard time seeing stuff in the viewfinder (can't see the whole thing at once, I hate that).
I use it sometimes, but not when it would be a distraction or when shooting concerts and the ambient sound level is over 100dB and I couldn't hear it anyway.
, I understand that the situation matters as well.
Take college for example. These idiots wear their little cell phones in class, get a call, rings their stupid ringtone that sounds nothing like the real song, and then gets kicked from class. it is all to funny to me.
If they, among others wanna get kiked outta class, that's out of my reach.
