I am constantly amazed by the apparent resolution of my 1DM3 images, as compared to those i got from my 18MP 1.6X crop sensor camera (the 7D) ...
I have yet to use my 1D3 to shoot airshow performances (heritage flights, Blue Angels, Thunderbirds, etc) so I don't know how it stacks against the 7D when using the 100-400L.
I still love my 7D because it's quite versatile, and I think that having access to near-1D performance for much cheaper helped me to get back into aviation photography and to have as much fun as I did for over 2.5 years until I had money for a 1D3 (when I got my 7D, the 1D4 was merely a year or so old, so finding a 1D3 for around $1k was not possible). I still think the 7D is a pocket 1D of sorts, but I do have one complaint: it's way too noisy, I'm pretty sure that Canon could have done a little better, or maybe kept the resolution slightly lower for better noise control.
