Just cleaned out my 10D yet again... and I'm using it with a "sealed" 24-70 2.8L lens. I'm getting tired of shots getting tarnished by dust bunnies. Sure, I can use the clone tool, but it still sucks.

My D60 *never* needed to be cleaned. Could it be that magnesium body attracting dust? Who knows. Does anyone with the new Digital Rebel find dust bunnies collected on the sensor?

Here's a surefire way to find them:

1. Set your camera to AV mode and set the aperture to F 8.0. Take a picture of a very clean sheet of white paper. Make sure the whiteness fills the entire frame with no borders or anything else in the picture. You'll probably need to set your camera to manual focus since it won't have anything else to focus on.

2. Download the image to your computer. Open it in Adobe Photoshop and then go to Image->Adjustments->Auto Levels. Or, you can just hold down Shift-Control-L

A strange-colored image will appear.

3. Look for random dark spots on the new image, which will be the dust particles on the sensor. Follow the manual's instructions to clean them off so they won't screw up your next critical shot.

I think I'll just wait until dust consistantly shows up in my regular shots before I worry about trying to clean it.

Carbon, you must be the lucky one.

My 12 months old D60 started to show dust spots on certain images a few months ago and using clone tools have been a regular practice. I haven't had the courage to 'wet clean' the sensor yet but just using the blower as instructed by the manual.

does the blower help?

Not really but hopefully using the blower regularly have prevented the dust problem to get any worse....kind of like buying insurance.
