Problem with meter and EF lens on 20d

[badrotation]

Well, lately, while using my Canon EF 100-300mm F4.5/5.6 USM lens, sometimes after a while of use the light meter will get stuck one notch above the center position in any of the modes except 'M'. It is getting really irritating, and I dont know if it is the body that is defective, or possibly the lens. It only happens after several hundred pictures are run through the camera.

The only way I have found to fix it was actually reset the camera using the 'clear all camera settings' in the menu. I then lose all my custom parameters, and custom functions.


Anyone have any experience with this problem, or have a fix?

I have V. 1.1.0 of the firmware installed

Nevermind, I am an idiot, and found out that all the times this has happened, I have accidently set EC (at least I think.) Time to take more pics, and see if that indeed was the problem or not.

Don't sweat it, friend. I had a moment of panic myself a couple of days ago when I couldn't get the meter to move at all from a -1 position by rotating the rear dial to adjust the aperture, at any mode setting; eventually I noticed that I just hadn't turned the power switch all the way on, so the dial function was actually disabled. :oops:

Glad you seem to have figured out what the problem was. (I'm realising more and more as time goes on that, based on first-hand experience, the single biggest contributor to camera malfunction is usually that sloppy nut directly in front of the viewfinder! :D )
