I've been shooting my kid's sports with a nikon 70-300G, which has been mostly OK outdoors. With hockey season starting, I need something faster. I've been looking at the nikon 80-200 2.8 and the sigma 70-200 2.8. The nikon is not AF-S and I'm concerned that the AF will be too slow for sports. The big advantage of the sigma is the AF speed, although it is supposed to be softer at 200. I know there aren't too many nikon shooters on here, but if anyone has experience with these, it would be helpful to hear your experience. I know dhmn69 has been taking great hockey shots with the sigma. Thanks.
