I use a panasonic Lumix Fz10. There has been the release of the 20, 30 , and 50 I believe now. Its a really good affordable camera with a 12 power optical zoom that relates to a 420mm with an fstop of 2.8 I believe. I used to use a Canon A2E with a 400mm fixed, but it was as heavy as a horse and most wildlife shooting is in poor light condition. A Canon lens at 400mm with an f stop of 2.8 would cost you over 10 grand. I understand the 20 and 30 are noisey but they fixed that for the 50. I have heard good things about the Nikon. I know several photographers that swear by it. The other thing positive about panasonic as it uses Leica glass.
