The 7D has 'horrible' ISO. There's been a big thread on how bad the ISO would be on the 7D.
I think the most important questions to ask you are:
- Do you find your 40D limiting and, if so, in what way?
- What do you shoot mostly and how do you think the 7D will benefit you in shooting what you shoot?
Do you even KNOW what you're talking about? Please quit spreading stuff like this if you have no practical knowledge of it. There is absolutely NOTHING wrong with the 7D as far as ISO performance goes; and it is certainly better than the 40D. And any noise that IS there is very easily dealt with in PP.
The 40D only goes up to ISO 1600, whereas the 7D goes to 6400 (expansion ISO settings aside). That's a LOT more leeway to deal with when it comes to lower light situations.
My 40D still sits on my shelf as a backup unit, but the 7D is a more capable camera in just about every way. However, it would depend on just what the limits you're feeling on the 40D are, as TijmenDal indicates with his questions, as to whether the price to upgrade is worth while.
My driving force for the upgrade was the ability to tone down how quickly the AF system attempts to refocus when using AI Servo focusing...that one thing alone was worth the upgrade for me. I've since come to enjoy the rest of the camera, as well. I would only consider two upgrades from this point, which would be a 1D MkIV or should I strike the lottery, a 1Ds MkIII. But that's based on shooting, primarily, birds, wildlife, etc.
