Does anyone have either experience or good information on the usefulness of the Nikon 200mm f/4.0D ED-IF AF Micro-Nikkor Lens for field photography? I've read that a good macro lens can add a lot of flexibility to setting up a good shot. I've also read that a long focal length may make it impossible to get a shot without either the stability of a tripod or the extremely fast shutter settings associated with flash photography.

Thanks
John
