Here are a few I took with the 40D and 50mm 1:1.8 MII
and uno mas
If you go to DPReview they have a pretty good review of this lens. Its not the best but it is cheap. I don't feel bad about mounting this on my old Rebel XT and going to the beach or getting into a situation where I would shudder taking the 40D. As for noise, I guess that depends more on the lighting conditions than anything. If you're really really worried about noise you might be better off selling the 40d and getting a 7d. That thing is an ISO monster in comparison.
