HI Steve,


I don't have an Arctic Butterfly but, have seen it used many times on video. Moose Peterson has an in-depth 4 part series that includes the Arctic Butterfly, sensor scope and other stuff. <a rel="nofollow" target="_new" href="http://www.moosepeterson.com/blog/?cat=114"]www.moosepeterson.com/blog.

This guy is a no no-nonsense wildlife photographer.
