I think that's just not acceptable. They don't have a single weatherproof camera under $4500. It's so lame. For about 5 days I've been at the Bonneville Salt Flats for a motorcycle time trials event. I have a 30D with me, which although it's a good camera, can easily get ruined here. What is up with Canon. I like Canon and most guys here are on Canons and almost all pros, except for 1 were on Canon's, but if a camera is not sealed, it's not a pro's tool. D300 is looking real good right now. However, there is an advatnage on being on Canon, because most use them you can swap lenses, borrow batteries, flashes and so on.
One of the press guys has a sweet 5D. But again, that cam is not weatherproof.
And there isn't a thing we can do about it. Unless Canon comes out with a direct competition for the D300 with a $1800 weatherproof cam.
