Ram Ledge is a stretch to photograph with any detail with a normal focal length lens.  When you begin to photograph with longer telephotos, that changes dramatically.  The photographs below were taken using a 500 mm f/4 Nikkor AF-S lens.  On a Nikon DSLR body, because of the telephoto factor, that becomes a 750 mm f/4 lens and 1500 mm f/8 when you use a 2X teleconverter as used for the bottom shot on this page.
