30D Main (Top) Wheel Getting Slow

Recently started having problems with the main wheel if I turn it too fast when setting slow shutter speeds. Feels like the wheel is spinning but not moving the internal gear - not clicking. Yet if I run the wheel buck up to higher shutter speed and the slowly run down to slower shutter functions like it should all the way down to 1/10 or slower. A little rubbing along the sides of the wheel improves performance for a while.

I normally shoot MA at 400 ISO / 20-40 shutter and occasionally rapidly shift speed to slower settings while shooting laser lit scenes. Any experience with this problem? Does careflully cleaning the wheel with a cloth moistened with distilled water help, or have worn this part out by rapid shiffting?

Re: 30D Main (Top) Wheel Getting Slow

Wow. This seems becoming more common with 30D. You are the 4th (I guess) to report this. (me included).

Till now going back and forth worked for me. Keeping fingers crossed that it should not give up totally..

Re: 30D Main (Top) Wheel Getting Slow

make it 5 then...

My 30D has same problem, I haven't been using it for about 3-4 months since I got GF1 (oops ;p) and found out about 2 weeks ago that the main dial started to 'stick', sometimes it click, sometimes it just 'slide'. I thought it's probably the rubber lost its grip or something.

Then I noticed that my shutter release also kinda 'sticky', when the camera achieved focus sometimes I can't take the shot! I don't think I've used the 100,000 clicks yet, mine's probably 25-30K tops.

Anyway, brought it to local Canon distributor and the guy can't replicate the problem. I insisted to send the camera to HQ for check-up & service anyway and have to wait for up to a month!!

I did call up the HQ and asked about the cost of replacing the shutter should there be need and was quoted about USD150. So it's finger cross now...:(

Re: 30D Main (Top) Wheel Getting Slow

Thanks for the update.

Please post once you get your 30D back if the main dial is fixed as well. And also what did it cost you overall...

Re: 30D Main (Top) Wheel Getting Slow

Misery loves company. This weekend I will try a little gentle cleaning with distilled water a cotton tip. Will watch for your feed back after the repair. I have a G11 and flash but boy will it slow things down in the clubs. A month would be a real pain.

Re: 30D Main (Top) Wheel Getting Slow

I also have the main dial slipping problem. Sometimes it clicks, sometimes it just slides... wonder I it can be repaired at home as the canon repair center said that it could cost $180 and over...

Re: 30D Main (Top) Wheel Getting Slow

I've just noticed this starting to happen on my 30D too. Not too concerned as I rarely use it now and at it seems to occur only occasionally. It seems likely to be a manufacturing defect as my camera has less than 10K clicks on it and most of the reports I've found don't seem to relate to heavily used cameras.
Probably not economical to repair it but if anyone has a fix I'd be interested.

mine came back from service

finally, I got my camera back. Canon found that part of the rubber underneath/near the shutter had worn-out most likely due to humidity?

I think I forgot to keep my camera in my drybox and left it inside my bag for several months since I got my GF1 in Feb

Anyway, it costs me about US$25 inclusive of part + labour and both my shutter and main dial are now working great! no sticky shutter, no loose main dial.

So I suppose I am happy despite having to wait for 1 1/2 months. I would recommend you guys try and send in your camera to get it sorted.

Re: mine came back from service

Will check with my local repair man to see if he can get the parts ordered. That long a wait =s buy a new body before repair. thnks for the feed back.

Re: mine came back from service

Thanks for reporting and good to know it does not cost as much.

I have no problem waiting longer as I have 7D in my arsenal.

Was this NJ repair center or the west coast one?

Re: mine came back from service

I had the same problem with my 20D a few very small drops of super glue inserted und the rubber sleve on the encoder wheel fixed the problem. I used a tooth pick to get between the wheel and the rubber cover and to keep the amount of superglue to a "minimum". It has worked fine for a couple of years. The rubber sleeve losened up due to creep and would not engage the encoder reliably.

Re: mine came back from service

Was that accessible without removing the top cover? Or am I misreading your comments?

Re: mine came back from service

Yes, I just lifted the rubber sleeve slightly with a small wire hook( Right at the end Very Small). You could bend one from a small paper clip or piece of music wire. The hook must be small enough to slip under the wheel cover through the the clearance in the camera body. You only need to pull it a little to get the superglue under the rubber against the endcoder wheel It only takes enough to increase the friction between the ruber sleeve and the encoder wheel.

Mine did the same thing before I fixed it, it would slip more when I turned it fast.

I did not remove anything from the camera. Again be careful It dosn't even require a drop of superglue just enough to increase the friction between the the rubber sleeve and the endcoder wheel. A full drop could create trouble inside the camera if it ran down inside. A easy fix.
