On my airline flight across the pond last night, I was rereading some portions of my GRD III's manual and came across something I missed during my first read. On page 20 in the notes section of the page (US manual version) it says: "In AUTO mode, a built-in neutral density (ND) filter is used for between f/8.0 and f/11. The smallest aperture available in AUTO mode is f/11." I don't see anyway to force the camera into those F stop ranges to see how this ND works. Anybody else question this feature? Why can't I turn the ND on in other modes?
