Paul seems to have a good workaround (panning), and I don't really know if the slow shutter speed will be an issue with what you are doing. It doesn't matter what shutter speed you are using above 1/30th on the 6x7, the exposure time (how long it takes for the exposure to happen) is 1/30 of a second. At 1/500 of a second. the entire frame gets a 1/500 of a second exposure, but it takes the camera 1/30th of a second to do it. Consequently, if something is moving very quickly in relation to the camera, there can be movement related distortion, even though the subject is sharply rendered. William Robb
