I'm after a good lens for my Nikon D7000 for filming things like extreme sports. BMX, skate, 4wd, motocross etc.
I'm after something that won't constantly be hunting in and out of focus as they go past or as I move around them as I will be using a glide cam for some good shots.
Any tips, tricks or pointers would be handy also.
