This is a constant recurring question :roll:

What's up with all the risksof gettingdust inside your DSLR :?

I've read somewhere that you can have more risk of getting dust from using zoom lenses constantly then simply changing from prime lenses :shock:

What do you think :? do they have a point :?

What they're talking about is that the action of zooming can cause the lens to act like a bellows, and suck air (and dust) into the lens and possibly into the camera body. Certain lenses and certain brands are more likely to do this than others. I've only really read about this in conjunction with Nikon lenses, but I don't have any specific information.

I personally think this problem is exaggerated. The camera body, aside from the lens mount, is closed. In order for a significant amount of air (and dust) to enter the camera body, it would have to blow through the body, and that doesn't happen.
