Looks pretty similar to the existing 80-400, which I've shot with quite a bit. I've never been super happy with the 80-400, didn't get as many sharp shots as I'd hoped for. It can't all be me Looking forward to seeing some reviews!
Ahh, PG. Way out there. Oh well...what ya gonna do, right? lol
Nice choice on the D7k. From everything I've heard about it, you couldn't have made a better choice.
