A poll to see how widespread control wheel problems with the a700 are. Please feel free to give details in a post. Please note this is for a700 only - if there is a need for polls for other models please state in a posting, but don't vote against this poll unless you have have an a700...

Front control wheel problems on a few occasions. A blast of compressed air, combined with rotating the wheel rapidly, solves it and in fact this problem hasn't returned in a while. But now that I have said that, it will probably happen again tomorrow .

Front control wheel problems after 1.5 years. Repaired by Sony under warranty. I use the rear wheel much less frequently.

Both wheels for me. I feel it's most my own fault though, I generally just leave it on my shelf with other, stuff, whether dust gathers quite quickly. When I leave it in a bag, it never really gets the problem. When it's left on and off the shelf, I get the problem all the time. I use a blower, but I really ought to get some compressed air like Mark has.

I pre-ordered my a700 from USA SonyStyle 9-2007, so I believe I have one of the first models.

Since picking up the a850 8/2009, I don't shoot the a700 as much. I suspect I have 40,000+ actuation's. I shoot manual almost exclusively, so I make extensive use of both wheels.

No problems with either wheel to date. I will note I don't shoot during the hottest, most humid days here in the eastern NC summer. If it's not too warm, I wear a pair of thin leather gloves.

I believe the a700 wheel problem is similar to the old computer mice that used rubber covered balls for tracking. The 3 tracking wheels would become gummed with debris, and cause skipping of the cursor.

Front wheel problem. It started about 1 year ago.
I try to use the front wheel as little as possible and use the joystick instead.
Luckily the problem has not worsened a lot since it started. And even more luckily the problem occurs almost exclusively while going through the pictures. F.e.: It seldom happens when I change the aperture (in A setting).
I never tried anything to get rid of the problem.

Rear wheel for about 1 month. I use it for exposure compensation. After I read this topic I blew it with the Giottos pump and the problem was solved(I hope for a long time). Thank you all.

I have encountered a problem when viewing photos and using the front dial to browse. At times it tends to skip photos ahead (or behind) when quickly rotating the dial. It happens with the rear dial, but not as often.

Glad to know I'm not the only one experiencing this problem.

I just cast my vote for rear wheel problem. It happenend when the camera was around 18 months old. Over the following 6 months, it was getting to the point where I just couldn't trust it (I use the rear wheel for exposure compensation. I tried the rocket blower method a few times to no avail. Out of desperation, one night I just used the rocket blower for around 5 minutes on it, turning the dial backwards and forwards slowly, then rapidly as I blew air in behind it. That "cured" it. I haven't had the problem since. However it's always there in the back of my mind that it will return.

When I was having the problem, I contacted the Australian Sony repair agent - they had no record of this being a known fault.

Cheers, Frank
