Even though I have decided against doing weddings for now, I am still toying with getting the 24-70 f2.8 II. Coupled with the 70-200, I will have everything I will ever need ... apart from a 5D Mark III of course :-D
I never reach for the 24-105, in fact the 70-200 and the 135L come out my bag the most. Just last weekend, I was walking around my local town and I opted for the 17-40L over the 24-105L. I guess I've read so many bad reviews about the kit lens, it's put my off mounting it on my camera. I know, I know ... silly, but because I've been blown away by the big bazooka since I've had it, I just want that WOW factor whenever I go out shooting.
