    Has anyone cleaned the sensor on a Canon? If so, what is the safest,
    economical way? Thanks

    Hello,

    I am very new to digital photography and photography in general. May I
    ask why you would not remove dust from you camera with canned air?

    Thanks in advance,
    Dave

    If it was just air in a can, it might be all right. However, "canned
    air" is really liquid hydroflurocarbon under pressure, and it
    vaporizes when you press the valve. Liquid droplets can get on the
    sensor. It's the propellant, not the air, that can be a problem.

    I have for many, many years used compressed air to clean the internals
    of my cameras including sensors and the chamber they are in. The
    difference between my air and "canned air" is that I soldered a tyre
    valve into a spent "canned air" canister and used a bicycle pump
    originally but now use an air brush compressor to pressurise it.

    The method is cheap and effective. I guess you could also use a football
    with a hose coming off it or an airbrush compressor by itself and get
    the same results once the sensor gets it's first (wet) clean.

    Initially I think you'd be best off using a wet swab because a lot of
    cameras come from the factory with a film of muck on the sensor filter
    that is not just dust. Trying to get this off without isopropyl alcohol
    to dissolve the slime could make it worse.

    You can buy isopropyl alcohol and a fine, synthetic camel hair artists
    brush for a few bucks. I made a swab holder from a rubber bowl scraper I
    got out of the kitchen and cut up a glasses cleaning cloth for the wet part.

    Then you can use the artist brush to get any future dust off the sensor.
    Whatever you do, make sure the battery is fully charged because if the
    current holding the mirror up suddenly goes off, the mirror (many
    Canon's are spring loaded) can return and shatter as it hits the brush.

    As usual with anything like this... What works for me might be
    disastrous for you so take *ANY* advise you get on Usenet with a degree
    of caution you might not otherwise apply!

    The three red-circled spots in this:
    http://i48.photobucket.com/albums/f244/cooper213/spots.jpg were dust
    particles on the sensor of my Nikon. I bought a Giotto rocket blower,
    followed the directions in the Nikon manual, and the spots are now
    gone.

    The downside is missed shots because of the time it takes for the sensor to
    clean.
    Learned that one the hard way.

    An ear syringe from my local pharmacy works just as well and costs less.

    Huh!
    Missed shots??
    If you are in the field and do not have the opportunity to clean, you
    take the shot and clean up the file in PP.[/QUOTE]

    he's referring to automatic sensor cleaning, making power-on take a
    little longer.

    Of course. I as replying to Paul's comment about self cleaning every time
    the camera is turned on.

    Invest in a Canon Rebel. It cleans the sensor when it's turned off...

  13. I've used both the nylon brush method and sensor swabs. If there are
    multiple dust spots, quite often I'll have to clean the sensor more than
    once to get the dust off. Now, I use the Dust-Aid Platinum and it works
    great, I get multiple dust spots off in one attempt.

    Not so easy to take the shot whilst the camera is booting up and shaking
    its sensor!

    Aww! Don't you know that Murphy says the targets will appear only if your
    camera is turned off with sensor cleaning on.
    Which was my original point. When you are in the shooting environment, keep
    your camera on, try to anticipate the most likely lens needed and keep at
    least one extra battery and CF card within easy grasp.

    It's very easy, as on the Canon 450D at least the camera stops sensor
    cleaning when you press the shutter.

    Ditto the 50D and probably every other Canon.

    Doesn't the MB-D10 add a lot of weight? I have problems with my 70-200.

    I use a SD9 remote flash power pack and a MD10 as well. The SD9 I carry
    on my waist belt along with water and a second lens. This is standard
    wedding photography kit for me. The weight is something I've had to
    contend with since at age 17, I was sent into the world with a Speed
    Graphics, a pocket full of flash bulbs and a shoulder bag full of double
    dark slides.

    The weight issue can be easily solved. Dump the DSLR and go for a P&S
    outfit. The difference in quality wouldn't be noticed... according to
    many of the posters here!

    I use a Pelican 'trolley' my assistant carries the rest of my stuff
    around in. Even then I often wonder if I have everything!

    Doing bush photography is harder on the load. Not so much for the flash
    but the extra lenses - all in a back pack. My 120 - 300 F/2.8 (Sigma) is
    the biggest burden but without it, I'd miss many of the birds in flight
    shots that have as much or more value as the seascapes that I get with
    a 20mm F/1.8 so the weight is not so much a problem as a logistics issue.

    Whichever way you look at it, you have to decide if you can carry the
    weight of your gear and keep working with it for as many hours as a
    wedding or trek into the bush requires or give up the business and buy a
    rocking chair!
