As I work today I've thought about it and I really think the best shot (for the DMR) is to shoot with two R8's, one with film and the other with the DMR and then crop the film shots after they are scanned to match the DMR's image. At that point you have something you know about. Then shooting a 1Ds Mk II with the same lens would be an added data point. What the target might be though - ah there's the rub.
