    No attachment there.
    Best way will probably be the copperhill method, check this site for more info on a few different techniques. Kablammo

    Yep, it's dust alright. There's no end of resources on the web, the site I posted is a great place to start. Once you decide on a method then you can further research it, put it into practice and then actually do it. Bear in mind Conns charges €50 a go so you'd be better off getting your own technique down first.

    Yep you got dust on your ccd... you will notice it more when using high F-stop numbers (greater than F8.0)

    Gunns of Wexford St have kits for cleaning 20d sensors ... make sure you get the right one though ... there are different kits for different sensors ... you want type 2 ... the kits come from these guys -

    Kits
    However ... I use the kit by Copper Hill found here -

    Cooper Hill

    This kit comes with very detail use instructions and advice (also on the site) ... it is a lot cheaper to make your own sensor swab and this kit contains essentially the same stuff as the kit sold by Gunns ...


    Essentially you take a risk when you clean your own sensor ... if you do it wrong you could be looking at buying a new Camera ... but it is not so scary if you take a few precautions as follows -
    • Do it in a dust and draft free environment ... e.g. in a clean living room a good while after hoovering since this unsettles dust and with all windows shut and a draft excluder blocking the door.
    • Wear a face mask and hair net to stop bits of you falling on the sensor
    • Use a directional light so you can see into the camera ... I use a head lamp (leaving my hands free)
    • Take Your Time ... don't rush it ... it can take a few hours the first time ... although once you are used ot it it only takes about 30 minutes
    • Only use the swab once per side (i.e. 1 Pec Pad = two wipes, one in each direction)
    • Don't leave your camera sitting open with the shutter open for any longer than necessry
    • Use Eclipse fluid ... nothing else ... you need to be sure this will evaporate quickly ... (you cna buy eclispe in Gunns)
    • Only wipe once each way then close off the camera and take a test shot ... don't panic if the first wipe makes it more dirty. You sometimes need to go a few times
    • Don't handle the cleaning pads at all if you can avoid it, keep them in a clean dry place and handle them with a tweezers as much as possible (I use a zip lock bag)
    Good luck!!

    it's not too bad you could get by with cloning out the spots!!

    bit annoying tho.

    my sensor is about 50 times worse than this - looks like the bottom of a waste bin in a fashion salon.

    i'm going to tackle it soon and i'll post the results too.

    this method works well: copper hill ... edit: oops, sorry I didn't see previous link in leinstermans post ...

    I used the above mentioned copperhill method recently and it really works perfectly.I bought the kit from a swiss site before christams for about €54.00 . It's very easy to do,took me four goes to get every spec off but the sensor is now spotless and I have the confidence to do this over and over again now.I'd highly recommend it.
