You guys rock! I am going to have to find a dof calc myself.
Going to meet some Z club friends at a hydroplane regatta car show tomorrow. Taking the Sigma "bigma" 50-500. Hope to get some decent shots. My buddy that went last year said the Z show guys had the best seats in the house. Hope the weather holds out.
