Sensor dust again??? Please give advice.

I just had my sensor cleaned canonand I don't even recall changing the lens in the last month (since it's been cleaned). Take a look at the dots in the upper right corner. Is that sensor dirt? What should I do? THanks.

I'd 99.9% for sure say its sensor dust. Best solution is to learn and clean it yourself or edit it out in post processing.

I use a rocket blower which USUALLY gets it out. Just remember to hold you body with the lens hole facing down. If that doesn't work I use a visible dust brush I purchased from bhphoto.com. That REALLY does the trick. It's not rocket science to blow the dust off your sensor once in a while. Once you do it a few times you'll be like "I sent this to canon for this? WTF was I thinking?"

Get used to it. Happens even if you do not change lenses. Just a way of digital. Get a rocket blower and blow dust off your mirror and sensor from time to time. You should try using a 100-400L, dust machine.

Yeah some lenses are notorious for sucking in dust as your zooming so you can still attract dust without changing lenses. As mentioned above give the rocket blower a go first. Although it's designed to keep condensation out of its body give it 5 to 10 squeezes away from your camera to ensure none has settled before unleashing it on your sensor. If that doesn't work then go onto the copperhill method.

I'd say it's because your sensor chamber is dusty. The mirror throws the dust at the sensor. Some cameras are dustier than others - I'm not sure why this is - maybe differences in production lines or something like that. I cannot be sure, of course, but I would bet this is the case for many that consider they have a "big" dust problem.

I've seen multiple posts where the poster says that one model "attracts" more dust than another. For instance, I had a very clean 300D - I never noticed any dust in practical use. Then my 20D vas _very_ dusty out of the box. I'd estimate that with the "dust test" there were 200-300 dust spots that I could make out - out of the box. I have to clean it regularly because more keep coming.
These reports of one model attracting dust than another are contradicting - somebody had a very dusty 300D but had no problems with 20D. So it's not a model specific problem.

I, too, use the copprehill brush.

A very good point that I believe a lot of users dont realize.

Even if you haven't chagned the lens for a while, if have a lot of dust in the camera (say from a previous trip somewhere), then you will have dust on your sensor quite a bit. I took my 20D to the beach a while back and I must have gotten some dirt in the poor guy because the sensor would get dust and dirt on it all the time for a couple of months. After some time and a few cleanings, things settled down back to normal.

Thank you for all of your comments! i will be ordering the rocket blower if that doesn't work I'll get the brush. But isn't it better not to touch anything to the sensor?

I don't know how everyone has all these dust problems.... I'm by NO means careful about using my camera or changing lenses and I have only had to clean my sensor (actually it was one little spot and I just did it to do it) one time in about a year and a half. I must live/shoot in a dust free enviroment I also just used a rocket blower.

I'd try the rocket blower, touching the sensor with anything should be a last resort, rocket blower usually does the trick

There is a glass cover over the top of the sensor. So technically you wouldn't be touching the sensor.

I am still more confident with the rocket blower, its all about confidence

Is this the reccommended brand? Does it matter if it's small/med/large?
Giottos Rocket Air Blower - (Large) 7.5"
Rocket Air Blower - (Medium) 6.6" Rocket Air Blower - (Medium) 6.6"

Thanks

Thats it, the medium is perfect
