Currently using the 24-105 with a 70-200 f2.8 IS, have considered the 24-70 v1 because the price is lower, and it still has pretty great reviews, not as good as the v2 of course.
I mainly use the 24-105 when filming. The IS is really good. Any advise on one or the other, if I were to make a choice to stick with my 24-105, of switch to the faster glass?
