I'm in a quandry. I shoot 2-3 weddings a year. I mainly use Tamron 17-50 and 28-75 f/2.8. I also shoot senior pictures and local baseball teams (mostly my sons)
I've not been very happy with the Tamrons. Though sharp most times, I find the low light focusing leaves a little to be desired. Not as consistent as I'd like.
I'm considering several lenses. 1) the 17-55 f2.8 IS - everything I've read says it has the quality and sharpness of an L lens, but has dust problems. However the IS makes it great for hand holding in low light. However, the 16-35L has the quality and build of an L, the same aperture, but lacking the IS. Does anyone have these two lenses and what recommendations can you offer.
Also under consideration is the 24-105 L f/4 IS and the 70-200 L f/4 IS. According to Canon... the new 70-200 has a better IS system capable of hand holding at 1/15th. This may be sufficient for low light situations.
I have limited funds, but am willing to take a leap of faith.... sort of a....... "Build it and they will come" scenario (of course I mean more paying jobs to pay for the leap of faith.

just kidding, I'm leaning more towards the 17-55 now. I think the IS would really make the difference in my situation.
