I want a 300/2.8 and VR is out. It's simply too pricey for my pocketbook. The only choices I'd consider are the AF-S version 1 and the AF-S version 2. I know that version 2 is a bit lighter and focuses a bit closer. Otherwise, what kind of difference is there in the optics of these two beasts? I really couldn't find any reviews differentiating them. Or maybe I should go for a new Sigma 120-300/2.8 and get OS to boot. This is mostly to satisfy a bit of NAS. Practical applications for would be for some youth & school sports, local wildlife including the domestic variety. Maybe some portraiture though that would be overkill as I already have a 70-200. Thoughts? Thanks in advance.
