Does anyone have any wide open comparisons to the two? I really want to see how the OOF areas are and the sharpness/color rendition varies between the two. I'm thinking of selling my Sigma 70-200 HSM Macro and either going with the: 80-200 AFD / AFS or 180 2.8 + 85 1.8 I don't like the weight anymore, and if I'm getting out of PJ work, then I'll be getting out of sports (which I rarely get to shoot anyway these days even though thats what I'm mostly good at). I'm thinking more for weddings and events where I can't stand the weight of all that lens and camera on one shoulder. I don't mind 2 cameras since I've been carrying two cameras for the past 3 years now. HELP. I know its a good lens, but I want to make sure it would be worth it as I hate buying and selling.
