Now when did I ever say anything was impossible? What I said was "MOST" professional sports shooters use Nikon or Canon bodies, remember? I'm assuming the E-XXX line is a "consumer" grade line, hence the small and almost useless viewfinder. The Canon XXXD line is consumer grade also (350D, 400D, 450D, etc ie Rebel XT/XTi/XSi) and also shares the small/useless viewfinder. From your post, it sounds like the E-XX series is similar to the Canon XXD series (pro-sumer grade), hence the larger viewfinder, but not as big as the pro-grade E-X or Canon XD (ie 1D/5D) series, right?
I used to have a Canon Rebel-series DSLR and I, for one, do not miss the small viewfinder. The large viewfinder of my 40D and 1D make it easy for me to place a single focus-point right between someones eyes and track them with that single point as they're moving. What I'm saying is IMPOSSIBLE is that I would not be able to do that with a small viewfinder. Instead of putting words in my mouth, you can quote me on that.
