The 50-200 drops two thirds of a stop to f/3.5 by the time you reach 200mm. I personally think this is a good compromise on the part of Olympus. If Olympus designed a 70-200 f/2.8 for the E-System, it would be of a similar size and weight to the sigma one.

My apologies for my misunderstanding. In that case, I agree about the compromise: The 50-200 is much more manageable.
