Shooting Eagles!!!

Went to Sauk City today to try to photography the eagles. No great shots for my first time doingit but I got some OK ones. Check out my flickr account to see them. One thing I learned. I HAVE to get a teleconverter. My 300mm F4 Nikor lens just is not long enough. A 1.4 should be fast enough but possibly not long enough. I am afraid to buy a 2.0 tc because of quality and the speed. I do want to get one soon and go back before winter ends.
