I've had the same problem with my XTi. Didn't ever know why, just knew that I could use the battery grips wheel and it magically fixed itself.

Bushymonster Loc: Oklahoma City. OK.

I have an off brand and never had the problem but it's good to know in case I run into it. I can't get mine to stop between clicks. I have the T5i.

Please, Explain that is "shutter wheel" Can you use termination same as is in Canon manual?

It is referred to as the "Main Dial" in my Canon manual. I think that this concept was introduced by Canon with the T90 in 1986, and was then called the "electronic input dial". It is the knurled wheel or dial adjacent to the shutter button.

Over the years I've used five or six different Canon BG-E2/E2N grips without ever experiencing the glitch you're seeing (on 30D and 50D extensively, plus a bit less on 20D and 40D). Maybe I was just lucky.

I have noticed that the grips can lose electronic contact (causing the camera to drop dead in it's tracks) during long shoots, when the grips gradually loosen. All it usually takes is slightly re-tightening the attachment. Occasionally I've first removed the grip entirely and cleaned in between it and the camera, too, when working in particularly dusty conditions.

There was a more severe version of this, a known problem with very early BG-E2, when the grip was first introduced along with 20D. Those grips had a somewhat poor fit to the camera and made very minimal electronic contact. At one time the Canon USA website had a white paper showing effected serial numbers and offered a fix or replacement... Plus there were a lot of DIY repair methods shown online by users. Later BG-E2 and BG-E2N were much better but still could loosen, in my experience.

The other thing I've noticed occasionally with those and other grips is that I'd seem to bump and accidentally turn off the rotating switch on the end. The camera still works with the landscape-orientation controls on the body itself, but suddenly the portrait-orientation controls on the grip don't do anything. Sometimes it takes me a few seconds to figure out what's wrong... it so rarely happens.

I've also bumped and inadvertently changed exposure settings, or tripped the shutter accidentally while carrying the camera hanging from a shoulder strap... Tend to carry them "backwards" now to help avoid this, but that exposes the mode dial on the lefthand shoulder of the camera to unintended changes (newer models now have a locking button on that dial to prevent this).

But, overall and besides the occasional "user error", I've found the Canon OEM battery grips to be good and reliable. I've used them on all my Canon DSLRs, as well as on film SLRs: BG-E7 on 7D, BG-E11 on 5D Mark II, BG-E2/E2N on 20/30/40/50D, BG-ED3 on 10D, PB-E2 on EOS-3, BP300 on Elan 7E/7EN... and even various winders and motor drives on AE-1, A1, F1 and others.

I tried to duplicate the problem with my new Vello BC and did.
Turning the BC OFF did NOT solve the probelm, good info.

Thank you Marty D.

Thanks for posting this, it's definitely an important subject! Luckily I never encountered such a problem with my grips.

I have a 60D with a Canon battery grip and have had no problems.
