This is a pretty interesting upgrade here, Not much in the way of "Holy cow! I can't believe they managed that!" but it is looking very refined and polished, much more so then the 20/30D.
There's an awful lot of stuff in there that I'd like on my 20D/30D bodies, but I can't say it'd be worth the money it will be when it first enters stores.
Though it'll be comforting to know that future bodies will have all this stuff and more for when it comes to replacing a body.
The
replaceable focusing screens and the new grips look really really good. Alas, maybe on day when i actually need to get a new body.
Personally the "weather sealing" doesn't bother me much, the sealing on the CF door/ battery compartment are the last of my worries, the electrical contacts are FAR inside the body, nearly certainly too far in for rain to reach. I'd be much happier with water sealed buttons.
Also, the IS lens updates look very interesting for people on a budget. Canon clearly trying to compete with the in body Anti-Shake types.
[EDIT] Also the new AF system looks really hardcore! I
REALLY could do with that!
