I started with a Nikon D50, then went to the D80, then the D300 and then the D700. I am currently using a new D800. We still have the D80 for a backup. I usually carry the following lenses in the field: Nikor 10-24, Nikkor 24-70, Nikkor 70-200 VR, Nikkor 200-400 VR, Nikkor 105mm VR Micro, and Nikkor 1.4X and 2X converters. I use a bogen 458B tripod With a Bogen mid size ball mount head.
