Canon 7D mark II main dial issue

Okay, I've done some web searching and seen some issue with the rubber on the main dial (by the shutter) slipping. I'm not sure that is what my problem is. I feel it click every time I rotate it, but sometimes it doesn't make a change. For example, in Av mode, the aperture will start to change then for a couple of clicks it doesn't. Same for shutter speed in Tv mode and also scrolling through images in playback. I've read about the rubber part slipping on the inner wheel of the switch, but wouldn't that be a smooth feel instead of still feeling the detents? Or does that come from the bumps on the rubber part of the dial?

My assumption is that the problem is in the switch/dial not slippage, but wanted some other thoughts on the matter. I'll run it down to the local camera store over the weekend for an opinion, but a trip to Canon for repairs is more likely, I suspect.

Oh, here's the fix I found for the rubber slipping, if anybody is interested. Since it doesn't seem like my problem, I haven't used it.

Do you have a battery grip? On some cameras, the lower dial interferes with the upper one.

I have one, but it hasn't been on the camera in over a year. Good point though.

I don't know anything about rubber on the main dial... but I do have a problem with the main dial of my 7D2. Like you experience, sometimes it takes more than one click to make a change to the aperture or shutter speed. I have about 40,000 clicks on mine. Maybe it needs cleaning.

Hmm, I've never had a problem similar to that with any of my Canon bodies. I wonder if it could be related to the heat and humidity of your location.

Heat and humidity of Calgary??

Lol. Yep, those hot winters in Calgary! Actually, RMyers, to whom I responded, is in Austin Texas. At this juncture I have no idea whether the problem he's describing and the problem you have are definitely related. Extra variables can sometimes confuse a situation.

Nice thought on the location, but was doing in NM in 20-60 degrees F. So not dependent on temperature. Honestly it didn't bother me too much until I got a 5d4 and it works perfect so it became more obvious and a bit frustrating.

I'll probably contact Canon and see how that process plays out, cost and time wise.

Are you going to attempt the glue fix suggested in your link. If you do, please post the results. If it were me, I would probably use a toothpick to apply the smallest drop of glue I could at two or three locations between the Rubber and the wheel itself.

It's an odd problem because it assumes that the rubber around the wheel has somehow stretched out slightly and lost its grip. I'm currently having a similar problem with the rubber on the zoom ring of my Sigma 18 to 35 mm F/1.8. it's obviously stretched out a little bit although it doesn't slip.

The rubber doesn't seem loose. It is hard to even fold it back to look. Debating about a CPS membership. $100 for Gold and I've got the equipment for points. Discount on repair, free return shipping, plus gear cleanings. Might actually make sense this year.

Good luck with it. Perhaps it's an electronic issue. Let us know how it pans out.

Probably degraded electrical contacts.

That's what I'm thinking, or an intermittent circuit board problem. .

Many people would say, "I think it is a short circuit!"

I have exactly the same problem - when using the wheel to zoom in or out it gives erratic results. Also, when using it to change aperture settings it sometimes go from larger to smaller back to larger while scrolling!

My guess is that the electronics inside the wheel have gone belly up. I just had a mouse doing the same sorts of things when using the center wheel. New mouse cured the problem! New 7D in my future?

Did you find out anything from Canon or CPS??
