Dust Spot Canon EOS 5D Mk III

Tue Feb 19, 2013 3:56 am

Hi guys.

I found out while downloading my shots from Saturday, that they were coming out with some dust.
I tried the dust clean function and then went back to the airport on Sunday... to my surprise, the dust spots were still there.

I tried removing them with a dust blower and tried also that same dust clean function (on a couple of occasions). It didn't work again.

So i came back home, tried even harder, and it is still there.

Has anyone had any similar troubles?

Can you guys recommend something?

Thanks.

Juan,

You've done the first stages of a sensor clean, but you have two options now really. Either send it in to a camera centre for a sensor clear (costly and time consuming), or get yourself some sensor swabs and do it yourself. While most panic at the thought of doing a sensor clean theirself, it's nothing difficult and only takes 5 minutes as long as you follow the instructions carefully. I do mine every 3 or 4 months. For example, I use Dust Aid.

MAKE SURE YOU BATTERY IS A FULLY CHARGED ONE DURING SENSOR CLEANING OR YOU RISK TOTALLY DAMAGED YOUR CAMERA!

This site and tutorial takes some beating

http://www.copperhillimages.com/index.php?pr=tutorials

I bought one pack of swabs (they are not cheap) and have given eight of the ten I bought away now. I re-use them by using a new Pec pad as described on copper hill.

Eclipse cleaning fluid is also expensive and I think the bottle must be slightly porous as it was empty after a couple of uses despite being tightly closed. I bought some Iso Propyl Alcohol and use that now instead. Switching you camera off and back on every now and then does an automatic clean but that will only remove anything loose and it sounds as though you have something stuck to the sensor.

When using film we used to turn our backs to the sun when changing films. I think we need to turn our backs to the wind now when changing lenses !

It was that long ago that sensor dust was a constant pita, and sensor cleaning was pretty much a weekly ritual!

Happily current sensor cleaning technology is pretty good. I don't think I had to manually clean my 7D in the 18 months I owned it, and my 5d3 has been equally good over nearly a year - occasionally a dust spot appears, but the sensor clean has dealt with it.

But I guess there will be some conditions where the sensor clean can't cope - particularly sticky dust etc.

Getting the proper cleaning materials (swabs and fluid) is not cheap first time round (sure, it will do a number of cleans, but the initial cost is high - and this is not an area where you should attempt to cut corners). Also, if you haven't done it before it can be a bit tricky - you need to get the amount of fluid just right, and just the right amount of pressure on the brush. I also find full frame sensors harder to get the corners clean.

I would suggest getting this done for you - some camera stores offer a cleaning service. If you only need to do this once or twice a year, it will be cheaper and less stressful than attempting to do it yourself. If however you find you are collecting dust on a regular basis, then DIY would be the way to go.

Cheers,

Colin

I just use a mix of dust blower and a visible dust sensor brush to keep my 5D2 and 5D3 clean. Do it once a month or so, just as a matter of housekeeping. Depending on how often the 100-400 gets put on the 5D3 does alter how often i clean it.

Hi Mick , just watched the how to video on that link narrated by Kermit the Frog , looks very effective .
May give that a whirl , id used the swabs before but never actually left the solution to soak right up , plus the sweeping of the mount .. very good advice !

cheers Tony

Thanks to all for your contributions.

I'll go thru the procedures recommended and afterwards decide.

I'm a bit nervous about touching the sensor myself. I'll have to think it twice.

Thanks again.

I have the same issue. The built-in cleaning and blowing air did not work. I have about 3 stubborn spots that I've just about run out of patience with. I ordered a cleaning kit with the swabs. From what I'm hearing it should work wonders. We shall see.

You'll be nervous the first time you do it, but as long as you follow the instructions carefully, it's nothing difficult and certainly nothing to worry about. As long as you aren't rough, you'll not do any damage to the sensor. If there's one thing I hate, it's removing dust spots from photos so a quick sensor clean saves all the hassle. You'll wonder why you didn't do it before!

A quick way to look at how dirty your sensor is, point the camera at the sky or something uniform, stop the aperture down as small as you can, f/22 say, then take a photo. Don't worry if the shutter is too slow, this will show up any dust spots on the sensor clearly. I normally use a dust blower first and take a test shot. If the dust is still their, go in with a sensor swab then take another test shot and repeat until it's clean.

I'm using ear swabs and isoprophyl alcohol (85+ %) from CVS. I'm getting the same results when I was using pro sensor swabs . After cleaning I'm doing small air blow and everything works prefect. Quick check with f/22 or so but never got second chance to clean it - always after first attempt sensor was clean. I know it sounds like hardcore but it works. I heard it from pro photograoher so why not to try this?
