Why buy the 40D if there's a 50D on the market? If you're planning to keep it 3-5 years I'd definitely go for the latest.
I had my 40D two years now and it feels outdated compared to newer cameras.
Feels outdated? ISO performance is better than the 50D and on paar with the 7D. AF is more than fine for any normal human. I used a 1DMKII for 5 months last year and the 40D more can keep up with Airshow/Aviation, Motorsport, and Sports in general.
