Terence wrote "As it is I find myself considering the 400mm F/5.6 Canon with a low-end body. " Moose Peterson recommends the Tokina 400mm f/5.6 on an F100 or F5. He claims it is abou the same as the all Canon setup. I have shot birds using an N90s and a Sigma 400mm AF lens. It works, thoughmay not be as fast as the setup Moose recommends. Yes, Nikon needs to get on the stick, but they show signs of waking up. The F100, new AF-S lenses, and even the 28-105 indicate a renewed vigor. Just hope it continues. _________________________________________________________ DO YOU YAHOO!? Get your free @yahoo.com address at http://mail.yahoo.com
