I then pulled the Kodak user manual and found it listed there.... Quoted from that user Manual... "For your images to be sharp and in focus, you must use either an IR filter or an anti-aliasing filter." "A removable IR filter (page 40) is included with the DCS 645. This filter, which is installed in front of the imager, filters out infrared light and helps protect the imager's coverglass." "You can replace the IR filter with an anti-aliasing filter which can be purchased from your Kodak equipment dealer. The filter performs the IR filter functions and helps reduce aliasing at certain focal distances." No where does Kodak tell you to remove the IR filter completely or to replace it with something else, like plain glass or something unknown to me so that the focus is correct. My conclusion, based upon the Kodak User manual, is that the IR filter is always present in this camera.......to " filter out infrared light".
