To cut a long story short, I shot my aunt's play last year with a 350D and Sigma 70-300 (ouch) and am now looking for a faster lens to go with the 40D I got at Christmas so I can do a better job of it this time around.
I guess the obvious choice would be the 70-200 2.8. But I'm anxious to try out shooting with primes, and as my shots were mostly in the 100-150 range I was thinking the 135L might be a sensible alternative. I've also considered the 200 2.8, but my thoughts are it's probably a bit long for what's needed, and if I'm going to get a prime, it should at least be faster than what I could get with the equivalent zoom option.
What're your thoughts?
