That's what I always say too.It's amazing that any sport's picture where made at all before AF. How do they ever get all those fantastic images in Sports Illustrated for decade's using Nikkor AIS glass. My head spins when I think about it. .
Unless that's long enough and you only plan on shooting in the middle of the day, when there is a lot of light, I wouldn't think that would be that great of a lens. That's not much reach and it's slow. But cheap enough, so if you are okay with less reach and slower, I guess it could work.Update:: Found the 300mm 4.5 AI for $160. woohoo!
