Sigma 150 macro
I am selling my Sigma 70-200 f2.8 to get a lighter lens for candid shots. I was planning on getting the Canon 70-200 f4 as it's about half the weight of the Sigma and the AF seems very fast. However I'm now wondering about getting the Sigma 150 f2.8 macro instead. So I was wondering if anyone could tell me what it's like as a portrait/candid lens? Is the AF fast and what's the IQ like?
