Title: Sigma 55-200mm for Olympus 4/3 system
Review: Despite what some reviewers have stated, I found the IQ produced by this lens to be unacceptable. The lens is cheap compared to the Zuiko 50-200mm or even the Zuiko kit 40-150mm and it gives a nice focal range but that's about it. Images are soft (unless the lens is stepped down to f8.0, which becomes a problem in moderate to low light conditions) and it produces a yellow cast, visible in most shots. I should have listened to the many negative reviews I came across and avoid it. In the end, I sent it back to Amazon for a refund. I won't recommend it not even if you are on a budget. Save you money util you can afford something better. I bought the Zuiko 70-300mm instead and that's one great lens...worth every penny!!!
