Well I went to my local shop to rent the Nikon 50mm 1.4D. Unfortunately I have a D40 and I have to manual focus all the time. I only got a chance to take a few pictures since the 50mm was not working to well for me at the Museum. Do you guys have any recommendations for taking pictures in a museum. While having the Nikon 1.4D I was using my "no flash" settings, Manual, Aperture settings. It was a challenge.
