70-200/2.8L IS vs. 200/2.8L II

[pcasciola]

Has anyone seen (or done) a side by side comparison of the 70-200/2.8L IS and the 200/2.8L II prime? I just ordered the 70-200/2.8L IS, and I'm wondering if it would be worth having both.

I just got my 70-200 IS today and one reason I could possibly find for the 200 prime is the weight-advantage it has. But I think the zoom has excelent picture quality. But the weight is something...

Instead of getting both, why not get the 135 f2 L.......its not only faster, but also has the reputation as one of Canon's sharpest lens.........next to the 200 f1.8.
