Its 2am and after reading Pirates suggestion I grabbed and applied what I thought was the sensor cleaning fluid but instead found it was lens cleaning fluid. The skipping is stopped huzzah. Long may it remain so.

Well, there's another solution that works

Sometimes the simplest methods work best . . trial and error. Well done on a positive result. I think it's essentially a build-up of gunk/fluff and/or film on the contacts, but if it works for you . . .

Lens cleaningg fluid isn't a bad idea. It is (usually) iso propyl alcohol and dries quickly without leaving any residue. It will shift most dirt build up from most things. Switch cleaning fluid usually leaves a slightly oily residue and this can get into more delicate parts of the camera with adverse effects; used sparingly, it should be OK though.

That is much less destructive than MY first battlefield thought of dashing the camera against the rocks because the skipping control wheel was driving my batty! I'm glad a calmer head prevailed and a few drops of lens cleaner did the trick.

Hi everyone! It's my first post on this forum, so I would like to say hello.
I also have problem with this control wheel in my Alfa 580. Could someone give me a tip or picture where exactly should I put a contact cleaner without disassembling? In the middle of this scroll in up and bottom? I really don't understand at all how to do this with drinking straw.
Best regards and sorry for my bad english, but i promise to practise :)

Ahoy!

Welcome to the Dyxum family. You spray into the gap above and below the control wheel itself, though follow the guides and methods posted. It couldn't be simpler to do, but if you're still struggling, then re-post, though it would be good to know that between us that the skipping control wheel has been corrected or not. Are you inputting your camera settings manually or using the dreaded AUTO option? In addition, what image format are you using? RAW is the best as it's a digital negative whereas JPEG is the print version after you've done your image processing, but that's for another forum discussion.

Thanks for warm welcome!

Sure, after applying a contact cleaner I'll give You a sign if that helps.
I almost never use auto options. I often use aperture priority to control DOF or manual setting when I use a trigger with manual flash like Yongnuo. So this control wheel is using very often by me and when is cold outside it's frustrating when options jumps.

Sorry, forgotten about format. I used to shoot in JPEG+RAW. JPEG for fast view on PC, RAW when I want to develop a picture :)

Did the issue get sorted, and if so, what method worked for you?

Sony A850: Spilled a dollop of Diet Coke on the front dial, not too long after that things started skipping around never could seem to land on f/11 and was hoping a corrosive effect had not already caused damage that a blast of solvent wouldn't cure. I rummaged around the shop for some Mass Air Flow sensor cleaner and realized it was in my pickup truck which is miles away, but I did have a can of carburetor cleaner!? I gave it a test squirt on the back of my hand and it left a slight white residue, which cleared off in about ten minutes.

I followed the test shot with a localized double straw blast in the front dial of the camera and began spinning it upside down and blowing with a rocket blower; directly it became very stiff, spongy and remained erratic. I thought it would be necessary to open it up for investigation to see what i had damaged, and went looking for my jewelers tool kit. A few minutes later it loosened up and spun like it should, except that the controls are no longer skipping and bouncing around, in other words it worked.

If I need to do it again I'll use a proper electrical cleaner, but hey, it was either carb cleaner or brake cleaner and i think i chose the lesser of two potential evils

Well that fix lasted less than a day and the skipping has returned. I did a firmware update from Version 1 to 2 and blasted the front dial again 4 times in 1 hour this time with electrical contact cleaner no better.

May end up disassembling it for investigation someday, but for now it's nice to have a rear dial and joystick that work fine.

I have a Nikon entry level DSLR that only has a rear control dial that I never have found enjoyable nor convenient to use as there is just no substitute for a proper front control dial.

It could be that whatever is on the contacts will not dissolve in electrical contact cleaner. Maybe try lens cleaning fluid, or experiment by drying a drop of diet coke, and seeing what kind of fluid best dissolves it.

And welcome to dyxum!

Ok Thanks, I did use an optical cleaner in the front dial a few weeks ago with no immediate change. Then last week I shot a couple outdoor events about 900 shutter actuations and had gotten so used to relying on the rear dial that I just now realized the front dial is functioning about 90% proper, where as before it was essentially useless
