Earlier commentary I've seen on the SD Quattro has expressed skepticism that an infrared capture is possible, by removing the thin internal dust cover/ir filter over the sensor, as one could do with the SD1 and earlier Sigma interchangeable lens cameras. But each of these commentaries has provided no further detail. Is the dust filter you refer to like the removable ones in the earlier cameras? It appears that your image includes the infrared range. Infrared capture on the earlier cameras required removing the thin sensor cover, so as to admit IR, and adding a visible-light-blocking filter on the outside of the lens. Does it appear this would work with the SD Quattro?
