    i am having problems with lots of small circular marks on my photos (dust bunny's) or whatever they are called, i tried cleaning myself with
    delkin sensor scope till i thought it looked fine, i took a few shots with cloudy skies then noticed they were still there. so i then went to my local camera center and got it done by a professional and the test shot looked good on the white back ground but when i got it home it was just the same???
    any ideas????
    cheers ian......

    Can you post a sample image showing the marks?

    Have you tried photographing a patch of clear blue sky? Black card? White Card? If it was OK in the shop it seems strange to suddenly revert at home. Are the marks related to highlights or specific colours?

    Is it unique to one lens?

    The lines across the image look like dried solvent from the 'sensor-wipes' ?????......not good !!!

    A 'professional' sensor clean is needed, or let Canon have a look at it !!

    I NEVER touch the sensor on my camera....I just use a 'Hurricane' blower occasionally, which always does the trick !!

    Whoever cleaned your sensor wants shooting. I bet its worst now than before. Take it back to where you had it supposedly cleaned and ask them if they will pay to have it done at Canon.

    I agree with above - getting spots in a striaght line like that can only be manmade.

    But are they the same sort of spots you saw before the cleaning?

    yep looks like too much fluid been used and dried.
    Ive cleaned my sensors many times and its not as daunting as people think, just make sure battery has plenty of life. It sometimes takes a number of attempts, I use a blower to start then pec pads with fluid but only a few drops. I use a spot light then run the pec pads all around the outside first followed by sweeps across the longest side overlapping.

    Never had to clean my 5D2 sensor (so far) - and I bet you wanted to know that!

    I would send the camera into an a authorized repair center, such as Fixation for a proper clean

    Definitely been caused by the fluid not been taken back off and left to dry , however no reason it should not clean if done properly and it takes a very small amount of fluid one to two drops max.

    Ive had a Simuler problem, I used Elipse and PadS Which i was always Happy to reccomend, but recently I could get rid of them and after some research bought some "Smear awar which gets rid of the marks that dont evaporate or oil from the edges, Its put me off ever using elipse again. so after asking on another thread im changing cleaning method. but look up "Smear away"
