Leaving question as vague as possible for maximum response.
Curious here. I have the 85mm 1.8 and love the results. I see this 135mm recommended for sports, especially indoor. Just curious, at more than half the price of the 70-200 2.8 IS, is the difference in 2.0 and 2.8 enough to lose out on the zoom capabilities?
When and what conditions make one lens more advantageous than the other?
