Heron

Someone here should buy me an EF 100-400mm f5.6L. Then I could get a half assed shot of the bird and not have to crop in tight for this.

ditch your canon and get a Nikon setup with the 70-200 f/2.8 VR and the 300 f/2

And give up CFn 4? ellll no. As often as I have considered changing to Nikon (they seem to be more about the camera whereas Canon seems to be more about the money [talking about the cheaper cameras only. canon pro models own]) I just can't leave Cfn 4 as well as the oh so lovely CMOS sensors.
