The 40D review is nice to read but I see no big reason that would make me want 40D over XTi. Probably because I am still newbie in DSLR world, huh? So I am sitting on a fence counting to the moment when Canon rolls out a new 50D. No rush for me.
As for Nikon D300, the jury is still out.
Fionn, I see you take your pleasure in beating 40D into dust…but I still wait to see if D300 has more than just its 3’’ highly pixelated display.
