    can anyone tel me what are these? dust on sensor? last time i faced the prob too but just one short stroke, then, i spent $27 to clean the sensor at nsc, but after 2 weeks the dot appeared again, and now it has so many...

    is this must clean at nsc or i can clean them myself? coz $27 is not cheap... :'(

    Yup.... most likely it is dust.

    No really a problem..... check your camera manual on how to rise the camera mirror/shutter to do manual cleaning. Just use a hand blower and blow on the sensor for a few times. If the dust doesn't go away..... can send it to your camera's servicing centre or shops like P&G for cleaning......

    P&G Photographic Centre

    Hope this helps......

    Well looks like you need to take greater care of your cam.

    With dslrs, dust will always be a problem.. no choice. So just make sure you change lens fast and do it in a clean place, with cam switched off.

    You dun really need to use bulb function. If you do, the sensor is actually charged and may attract more dust. Better to use manual clean function.

    U don't have to use Bulb mode. There's a sensor clean function avail from the menu and u can clean from there. Just remember to use fully charged batts.

    Think TS is using D80, just use the mirror lockup for clean and use a blower to blow with the camera facing down. Becareful not to touch the sensor.

    definitely dust

    to know how bad it is, get a piece of white paper, focus to infinity, go close, shoot at f/22 or so, ev +1.0 or so.

    good luck and have fun screaming. i am very anal about dust, i understand how it feels, but sometimes it is also important to remmeber that you should not be too anal about it.

    mmm... actually no. Olympus have a working dust prevention system for like a few years already.

    other companies are also coming out with similar stuff... I think it is only a matter of time b4 the other companies get it right.

    I also change quite frequently but don't do it in dusty places. Also, back against wind, camera face down.

    If you want to try to clean the sensor, you must have the battery installed with a full charge.

    Go to the "Set Up" menu, then to "Mirror Lockup." That will lock both the shutter and mirror in the open position. Note: Use the one in the "Set Up" menu not the "Shooting Mode" dial.

    You can follow the Cleaning your Sensor instructions by Thom Hogan

    I had dust on my D80 once and this is how I clear it.
    Take off the lens with your camera body face down and mirror lock. Use a clean hairdryer and set to normal. On it for a few seconds to clear elements from the dryer first, then give the camera a good blow for few seconds. Presto it's gone. Using a hand blower is not forceful enough to rid off the dusts. Don't use those cleaning fluid as it may mess up the sensor. I had a friend who uses an expensive cleaning kit and his camera ended up at the workshop instead.
    Till today I never see dusts on my camera again.

    Point to note: Try not to change lenses in the open if it's windy and never expose your sensor to direct sunlight. Also make sure you clean the mount of the lens before you make the change.

    Hope this help.

    wet cleaning is necessary for welded dust, which is very common in humid countries like singapore. if you have not been getting that, then you have to be very , very lucky indeed.

    for simple dust use a normal blower will do.
    for stubborn dust, maybe can use a swiss blower but be careful of the metal tip.
