It's killing me, like I really need more gear. I don't like my kit lens and I am starting not to like my 24-120mm VR (I should sell them). I want a 2.8 for sure. But which brand?? So many choices. I think I am going Sigma or Tokina. The Nikkor is a lot money, but is it worth it? I am looking for a 24-70mm or 28-70mm area. This one seems too cheap: http://cgi.ebay.com/Tokina-ATx-Pro-...yZ106863QQssPageNameZWDVWQQrdZ1QQcmdZViewItem How about this one? http://cgi.ebay.com/Sigma-24-70mm-f...oryZ3343QQssPageNameZWDVWQQrdZ1QQcmdZViewItem This? http://cgi.ebay.com/Sigma-28-70mm-f...oryZ3343QQssPageNameZWDVWQQrdZ1QQcmdZViewItem Thanks for any info you guys input.
