Ok.. here I am talking about canon L lens again. I have the Sigma 24-70mm f/2.8 and I am not happy about it. It looks like the AF is hit or miss. The IQ isnt that great even when I made the aperture smaller to around f/4. This happens more ofthen when I am in low light or it is a lot brighter behind the subject. So I just listed it on CL for sale and I want to either get the canon L version OR keep the money and save it for the 70-200mm f/2.8 L. I read the review on B&H, it did get 5 stars but it scared me when I read the negative reviews. I dont want to be on the same boat again like the sigma. Comments and suggestions? Shall I just get the 70-200mm and be stuck with either my 50 and kit lens for a wider angle?
