Locking the camera down on a solid tripod, stopping down to where the IR wave lengths will also be in focus "may" very well provide a different result. All of us with M8's could spend time testing our various lenses, with and without filters, at various apertures, focused on various subjects, with various amounts of IR present. When discussing sharpness and contrast camera movement and subject movement must be absolutely removed from the equation (as much as is humanly possible). Peter's test, while interesting and informative, certainly did not reduce camera and subject movement to anywhere near zero.
