Golf Shaft Flex Distortion

I see a lot of videos and photos posted with radical shaft bend. My local golf shop has even posted pictures of professional golfers hitting shots with the shaft tip bending forward 4" at impact. They are using these photos to justify putting people into stiffer shafts. The problem is, that bend is not real. If the shaft and club head in the photo is not blurred then its likely it was shot with a digital camera that uses a vertical scan or rolling shutter method for catching the image. Anything moving will be distorted even though it is in focus. This video compares two cameras shot simultaneously at my golf swing. The club is a Cobra 3 wood, stiff Aldila shaft. My driver swing speed is 105 mph. I turn the camera sideways in the video to demonstrate that the rolling shutter will create distortion when the club is moving across the screen but not when it is moving up and down the screen. Some cameras have a rolling shutter that moves across instead of down. Those will distort the club when it is horizontal. Thus showing a true image at impact, if you get lucky and catch one of the frames at impact.
