    Posted: 05 February 2012 at 01:59
Has anyone else had a problem with the control wheel on an A580? Specifically, as I'm I'm adjusting the shutter from say, 1/4000 down to a slower speed, it will jump back up to 1/4000. If I slow down and very carefully work it down I can attain what I want, but as you can imagine, it can be a real pain. It seems like if I press the shutter half way after some adjustment and continue its not as bad. As my other cameras don't exhibit this behavior, I believe it's the camera. I've searched the forum and the web but can't find any reference point for this. Further, is this what happened to the A700 bodies? Moreover, is it something I'm doing wrong?

Sounds like the old A700 problem but personally not heard of it on any other bodies. There are possible temporary cures. Search for A700 control wheel and I'm sure plenty will come up.

I have the same problem with my A560, it has gotten worse and worse. I was ready to send it off to get serviced when I found this thread, and then did a little more research and found:

http://forums.dpreview.com/forums/readflat.asp?forum=1037&thread=30539266&page=1

Down the page a bit there is a response that details how to clean out the dial with contact cleaner. I just tried it with some basic canned air and it worked wonders, no more problems for me. I'll buy some contact cleaner too just to be safe but I am super happy!

Thank you so much for mentioning that it was a common issue with the a700!!!!

Same here, clean up the wheel as you spin it and some rubbing alcohol on a cooton swab is all it may need.

I am experiencing the same problem on my a850 Full Frame!

C'mon... where's the quality? I want to use my camera W/o this added annoyance. I was one of the first to have it on the a700, too, years ago. Three times it took to get it finally repaired. I even had to teach Precision Camera how to troubleshoot the issue so they could see it. They keep sending it back NPF (no problem found).

I am sorry to hear this.

I had the same problem on my A700. Cleaned it several times, but it didn't disappear in the end. Had to bring it to Sony and they replaced the part.

Sorry to hear it's appearing on he A850 as well, D-Schap. Fortunately my A850 hasn't got this problems yet. Good luck with yours, both of you!
Best regards

People, please go careful putting lotions and potions on or in your camera. The last thing you want is to put too much alcohol or contact cleaner about without knowing where it will end up only to find a big streak of it running across the sensor. I'd imagine the wheels are well sealed away from the vital parts but things do go awry as you already know.

It happens with any body that has rotating switches, it's inherent to the design and a design flaw IMO. I'd like to see them replace the dials with sealed rocker switches, problem solved!

I've had this on my a580 but I've just been blowing into one side of the switch which clears it. I'm guessing dust gets in there or something.

I tried using compressed air but it didn't help. If I want to change the ISO setting it does the same thing. None of my other bodies do this. I guess its time to send it in.

I used my blower on my A700 three Times. First two times it worked but the last time it didn't. It may have with a little perseverance but a couple of days later after driving back from a photo outing the focusing screen dropped out en route and got badly marked so I sent it in for warranty repair and got the wheels done at the same time. Had no further problems over the next 15 months. I'm hoping the weather sealing on the A77 may stop it happening. I guess only time will tell.

Unfortunately, this is a long time defect with Sony cameras and has affected just about all Alpha bodies that Sony has made. Sony seems to have no interest in fixing it though in even newer designs after the A700. I haven't yet seen a report with the A77 though so there is a chance that finally the design has been fixed. Here are more threads with additional information:
