I have an additional question. the only experience I've had with digital infrared was using an IR filter on my 10D. Gave me some potentially lovely images, but they were somewhat grainy (even at low iso speeds) and didn't have much fine micro detail and lacked those wonderfully smooth tonalities that the 10D was so good at. With an IR ONLY converted camera, do you get all the great potential of the camera at 100 or 200 iso (very sharp, fine micro detail, smooth tonalies, etc etc) but with all that wonderful light toned grasses and foliage, dark skies, and so on? Thanks, Eleanor
