I mainly use Canon equipment which I find to be reliable and sturdy enough for rugged outdoor use and the rigors of travel. I use two Canon 5D digital cameras and various lenses which include a 28-135,16-35 wide angle, 70-200 mm telephoto zoom, 300 mm telephoto and a 500mm telephoto. I also use a number of Canon lens extenders along with several Gitzo tripods and Wimberley heads for all occasions. For the most part this equipment covers the photographs I am searching for.
