Another great lens would be the 70-200 f4 L IS USM....although it's not as fast as the newer version of the 70-200, it produces incredibly sharp images.

Both the 24-105f4 and 70-200f4 are very appealing to me. Believe me, in cost and size, they are VERY appealing over the 2.8 versions. But the main point of me jumping to FF is for better low light performance. So it almost seems a waste to get f4 lenses when I need to maximize my low light potential. Am I wrong in thinking this way?
