Thread: Is this considered dirty for sensor?

    Default Is this considered dirty for sensor?



    No matter how I use the hand blower, the dust wouldn't go off. See especially the top right hand corner.

    Deserve to send for cleaning at the Service Centre? Or has anyone got worse?!

    I'm no expert, but I'd say it's dirty enough to spoil some pictures, especially where skies or buildings are showing. I went on a trip overseas and had just 2 dust specks, that meant cleaning up many many pix over the 200+ taken

    Fortunately they were easily blown off.

    Should send for cleaning. If not try shooting at larger aperture eg. f2.8.
    But if you shoot outdoor especially blue sky... you can't be using larger f-stop...so the spots will show up.

    just send in for cleaning.

    btw, if you take a photo like this again, try not to focus sharp on the paper, the dust particles will be much easy to spot.

    Yah guys, think I'll send for cleaning. No harm. Some stubborn dirts there.

    catchlights, actually, on the contrary, I find if the image is sharpened, I can see the spots better. The original image is not so over-sharpened. I did a USM on it.

    I got the exact same problem as u.. Got one obvious stubborn black spot on my sensor showing in my pic.. Try hand blowing it, but no matter how hard I blow, its still there.. Seems to me like a smear, but how can it be possible when I never touch the sensor b4..? I guess I have to send in for cleaning this week too.. Any1 knows whether cleaning of sensor is covered by warranty and if not, how much will it costs and how long it takes? Thanks..

    I suggest you get it clean if you use small aperture.
