5d2 in "M" Mode - Cannot adjust aperture

Yep. All have been cleared and nothing works. I will be calling Canon. Thanks guys!

Sorry to hear about the problems Tex - I only have the Classic 5D and this is something from left field....... but is it possible that either you have inadvertantly set a really low ISO or high one, and whatever aperture you are trying to set has no effect? So it "appears" to be non-functioning? - Stu

Unfortunately not. I have tried ISO's all across the board and it is not working.

Ok - you're way ahead of me on that then. I thought perhaps it was something "out of range."

How about another long shot: Kill everything COMPLETELY back to factory defaults. Turn the power off, remove the main battery as well as the WATCH battery. Let it sit for about two minutes, reassemble and repower.

I just called Canon in Irvine, CA. It is going in for repair. There is definately something wrong.

It sounds like the firmware problem being reported by lots of 5D2 users.

Try a different lens? Apparently it was the 100 f2.8 that was problematic but maybe other lenses do it too.

EDIT: Forget that, apparently the issue doesn't exist any-more!

What lens are you using?
(Sorry, but I saw a similar question once and the problem was the lensbaby)

Same thing happened on my new 50D, the main dial would do nothing at all. 10 minutes later it magically started working again and hasn't done it again since.

Damn that sucks van. Hope you got it brand new and have a warranty
