Insufficient information. You need to know which f-stop, and the focal length of the lens? > 2. How fast does your shutter open and close when set to 125? Insufficient information. What type of shutter (leaf, or focal plane), how fast the leafs or curtains move, etc? > 3. What f-stop do you have to use to have everything from 8 feet to infinity > sharp in your photography? Insufficent information. What is the focal lenth of the lens, what is the magnification of the final image. > 4. What f-stop do you need to get proper exposure with a #5 clear flash bulb > at 7 feet? Insuffient information. What is the film speed, what shutter speed? > 5. How accurate is the Sunny-16 rule for exposure? +1 to -3 stops, aproximately on a bell curve, so there is a much higher incidence of accuracy in the middle of the curve. So? Are you an old fart? Or, a whippersnapper? Ciao, Graywolf http://pages.prodigy.net/graywolfphoto
