I’m looking for an alternative to “The Beast”. I think I need something with just a little more range than my 17-55 f/2.8 for wedding photography and I want to get something less than a grand. That puts The Beast and the 70-200 out of my range, so I’m looking for a good alternative. Anyone have any experience with any of the 28-70 f/2.8 lenses from Tamron, Tokin or Sigma? If The Beast is a perfect 10 lens how would you rate yours?
