Eh!? Yes, possibly a silly thread; and maybe even a pointless one; but I'm trying to make a best decision; again.
Yes, I know the T1i is a Rebel and the 50D isn't; so apples and oranges; however. I'm looking for better ISO perfomance than the XS, faster FPS; and better a better AF system. Both cameras supply that; but one costs more than the other; and one has a video function that will never see use.
Another thing I'm looking at is money for glass; cause I still need better glass; so would my best option be to get the cheaper camera and use extra money on more glass; then later on make a bigger jump? (Into maybe the 7D range)
So save a few more hundred more bucks and get the 50D or grab a T1i; and start saving for glass faster? (50D also has microadjusting which I've heard is amazing, but I'm on the fence about that)
So:
Option A) 50D- 1000$
Option B) T1i- 600$ + 400$ for glass
Option C) Make your own option and give it as advise
