As a wildlife biologist, I frequently have the opportunity to see and do things that many people don't often get to enjoy. Photography has provided me with a means by which to share many of my experiences with others. To do this, I've chosen to use a Canon EOS 20D, Sigma 50-500 mm telephoto lens, and several other smaller lenses. My dream lens (some day soon...I hope) is a Canon EF 400 mm f/2.8 L IS USM with an attached 1.4x teleconverter.
