What Bruce said. Forty years ago I could manual focus any lens, every time. I could even pull focus on a car moving toward me. But eyes wear out faster than old manual lenses. I had a heck of a time focusing the 400 yesterday, particularly when working from my knees with the camera on a low tripod. Manual focus is largely in my past. Paul
