Tedz - You are a wealth of knowledge my friend. Thanks! Of course, I don't like the sound of "more powerful than traditional aerosol dusters" when talking about cleaning a sensor array. Misha - Along with better construction and better image quality/less noise (usually due to the larger element size of DSLRs) among other things. I dunno ... seems like a lot of frustration and wasted energy for something as simple as dust. Take 60 seconds to switch to cleaning mode, blow the thing out with a bulb blower and then go enjoy the hell out of one of the best DSLRs out there. But maybe that's just me. :) -=>Donald
