The 70-200 would be mainly for wedding purpose, as I said I love shooting portraits, is what I enjoy most from photography and the results the 135 are incredible. As much as I love it its difficult to use it in weddings, if I had another ff body and a 35 1.4 it would be another story but right now i cant afford it and I dont like much the idea of carrying 2 bodies (maybe in a future). Thats why I started the thread, because I love my 135 but I need a 70-200.
I agree. Rather than trying to answer your question outright, I was providing a process I would take to determine the value (to you) of the various lenses.
In my opinion, the quality of the 70-200 II is that good, but if portraits are your first love, and you use f/2.0 -- I suspect that giving it up might be a mistake.
Can you rent the 70-200 (or borrow) for a wedding so you can see how you like it. If you do, be sure to take the individual portraits with it too -- because that is, IMHO, the 135's strong point. If you find the 70-200 meets your needs....
And as another poster mentioned, even if you sell the 135 to get the 70-200 now, you can always pick up another later when funds permit. Of course I am making the assumption that, in the short term, the missed wedding shots are more important to you than the benefit provided by the 135.
