The Beast
Decided to try something completely different, and hired a Nikon 400mm f/2.8 prime lens for the day from Calumet. It only weighed 4.5kgs, chuffing huge doesn't really do justice to the size of the thing. Pictures weren't too bad, I'd need to practice some more with it though to get them just right - especially on something like F1 which I don't shoot often.
