I'm trying to hone my skill with the 80-400 VR at 400mm on a monopod. Sometimes I think I can get that combo to work... Here are some Snow Geese. All at 400mm, f/7.1, 200 ISO: Tried the same technique with Canada Geese and didn't get the same results: Would you think that this is more of an issue of my panning technique or did the lens just not focus? I had the camera set to AF-C... Thanks for looking! P.S. Are these images too large?
