ChrisF, I am asking because I don't know for sure but that lens you used it does have IS? Was it the original IS version of that lens? I am not suggesting you upgrade or anything, the shot you posted is very well done. I am just curious because of all the advancements in IS, VR, and VC it would be interesting to see how much of a difference the newer systems make.
You got a lot of detail without a lot of noise out of that 30D!
