<p>@Randy: <br />I am mostly in One Shot and AI Servo - never have I touched AI Focus. Yes, I am using BBAF. I'll try reversing them the next time I encounter the problem, thanks! <br /><br />I'll try to get it checked, hopefully it's an inexpensive fix. Thanks guys. </p>

<p>Hi all! I have a problem with my Canon 50D. There are times where the camera will be focusing automatically, and pressing any other button won't work - except the dials, the joystick and the shutter button. Switching to CA mode confirmed that the AF-ON is the problem - it says "Function does not work in this mode" (or something along those lines). <br /><br />How can I fix it? If I were to send it in for repairs, how much would it cost? </p>
