I want to purchase a cleaning kit for my Canon XL2 but don't want to spring for another Visible Dust 724 which got lost a while back. Is the size of the sensor smaller than that of a 1.6x size of my 20D? because on the visible dust website that seems to be the smallest size for the cleaning swabs. Anyhoo.. if anybody's able to lend me a hand please drop a post
I don't know much about cleaning kits, but I do know that the XL2 is a 3 chip camera. This means that the chips are behind a prism block and that the surface of the prism block is usually protected by some IR filter glass. Since the dust is not on the chip itself, it will not be in sharp focus, which is a good thing if you miss a spec.
You won't be cleaning the chips themselves (They are glued to the prism), just the IR filter. My guess is a cleaning technique will be found in the camera manual. I clean the lens port on my HD camera with a lens cleaning cloth and treat the filter glass as I would a very expensive lens surface. I like the microfiber lens cloths, and keep one clean in a baggie for the lens surfaces and the IR filter in the camera.
BTW, your chips are about 8mm measured diagonally. Quite a bit smaller than a 20D, but there are three chips instead of one.
