Sigma 50-150 f/2.8 OS reviews round-up

Thank you for this post. I am interested in this lens and will buy it for an event I have to shoot in one month, becouse last time my old 50-150 let me down - AF was too incosistent in low light and I expect it to be again that low. On the other hand, the 50-150 mm range was perfect. I am a little worried about the size though, less about the weight.
