Sensor cleaning.

So, its not that ive tried this or anything, but is it a good idea to gently blow some dust off of the sensor using a compressed air can?

Most people will tell you no.
I've been using canned gas since I bought my *istD in 2003 for routine sensor dusting.

Great, and I mean as long as you dont full out blast the sensor you know, just a light flow of air.

I think the real problem with canned air is the affect it might have on the mirror so just be careful as the mount is quite delicate.
The canned air that I buy actually says not to use it on camera mirrors.

The mirror is out of the way during sensor cleaning.

Canned air can contaminate the sensor with propellant.

Just post a link that is something other than someone's opinion.

You can still hit the back of the mirror and the mechanism it is mounted on, that's the delicate part.

Sorry to hijack the thread but how often should you clean the sensor?

When it gets dirty.
Seriously, I don't think there is a hard and fast rule.

It's not that delicate, and with the mirror up, the mechanism is under tension, which tends to keep things where they are supposed to be.
I'd be more worried about whacking something inside the mirror box while squeezing a blower bulb.

I use canned air. I was shown how to by a camera tech.
Keep the can straight up and down, never use beyond 2/3 empty. And always use short blasts, so as not to induce condensation.
Look for the brands that say they have no oily stuff in the propellent.

I saw canned air for sale @ Blacks Photography today, so it must be safe, I guess.

The canned air is also used for blasting dust off of film negatives and slides for printing or scanning as well as a number of other things. Just because the photography store sells it, doesn't deem it safe. Not saying you'll destroy anything by using it but I wouldn't draw that conclusion just because they sell it.
