I've had the camera for a few years and it's always been totally reliable. I've often used a varizoom devise for live event coverage and never had an issue. I plugged in the varizoom today and it wouldn't work. I unplugged it and tried using the regular zoom control. When I zoom all the way in and let go it slowly drifts out wide. I've turned the camera off, checked all the menu settings and completely taken the varizoom out of the equation and the problem has not gone away.
