  • Serious dust problem.

    Ok. So I had my sensor cleaned not more than two weeks ago for a cost of 35 dollars. Everything was cool. No dust, perfectly clean. So the other day I went to the airport to shoot for a while. Pictures are going good.
    Here's one I took within the first hour or so.
    (unedited)

    Now here's one I took maybe 30 minutes later.

    Mother$$#%#$!!!!! What the hell!!!??? Within 30 minutes this monster shows up. This is beyond a normal little dustspot that everyone gets. This is huge. It's fine in the sky but if it shows up on the plane (which is does when I take a centered photo) it's next to impossible to clone out without some unnatractive blob ruining the picture.
    My questions are, is there something I'm doing wrong to attract so much dust? I never switched lenses while I was out there. I keep the lens off for as little time as possible when I do switch lenses, I turn the camera off when I do aswell. I can't afford to spend 35 dollars every week and a half to get this damn camera cleaned. Is there a type of blower made for this? After seeing Matt Wilmot Sharp's thread about a scracthed sensor I decided that I'm not going to fool with those swab things.

    (And Matt, sorry if I spelled your name wrong)

    That's bad luck. My 20D was professionally cleaned and was spotless on it's return. 2 days of use later, dust was aleady visible again. I hadn't changed my lenses much either at the time. I'm dreading using it again after ZRH as I was switching lenses non-stop all weekend, although it doesn't seem to be too bad.

      Man that sucks. You should be getting no dust if you're not changing lenses. Is there any instability on the lens mount that would allow air into the body? Did you clean both ends of your lens glass before attaching the lens? Dust on the lens can fall onto the sensor. That's all I can think of...

        I'm not sure about any instability. I hear when you zoom in and out with a telephoto it sucks in air and can let dust in. Maybe this is what happened? Either way, I need to get something to clean it with myself. Can anyone recommend anything?

          CCD charging

          Keep the camera switched off as much as possible. when switched on, the CCD becomes electrostatically charged, and attracts dust like crazy.

          I still cannot understand how that gremlin got in so quickly... but maybe if you used a very high f stop, dust becomes much more visible.

            I cleaned my 20D with DigiSensor Swabs and Eclipse cleaning fluid...no problems. Try a rocket blower first. Sometimes it can clear those larger particles out...

              Where do I get these rocket blowers at? Any kind of chain stores that would sell them?

                I would think most camera stores would have them. It's shaped like a rocket and its basically just like any blower bulb only I find it delivers a bit more powerful burst of air. Its made by a company called Giotto's.

                      Cheap solution, DONT zoom like a madman, extending or retracting the lenz like crazy might be the problem ????

                        Lol well that's not really an option.

                          That certainly is an option. You don't need to zoom that much, leave it where it is and wait until you can work with the aircraft at that point. It doesn't have to be a full frame shot, there's a hundred pictures inside a picture.

                          From what a friend here in Cincy told me was that Provident on 7th charges $10 to clean your sensor and they do it right then and there in ten minutes. Great service.

                            Well I bought one of the little blowers from the camera store and it worked great. Got all the dust off in like 5 seconds.

                              Hi, I hope that you sorted out the dust, it certainly seemed very dark.

                              I use a set of brushes from visible dust to clean my sensor from time to time. You charge the hairs by puffing them with a rocket blower, or specialist camera compressed air and all the dust sticks to them as you gently waft it across the sensor.
