I'm seeing the need to have a 2 low-light lens system in place for indoor event photography, however my budget is a deciding factor.
Right now I'm seeing the Canon 24-70 f2.8 L mark 1 lenses pretty cheap ($350-$600 on ebay). And of course the mark 2 versions not so cheap ($800-$1300). I had to make this type of decision with my 70-200 2.8 L version 1 without IS. I'm happy with the quality and am used to using it now.
My question, is there anything about the 24-70 mark 1 lens that's really hard to work around that the makes the mark 2 version a better decision?
