Has anyone got any experience of using this lens for field sports (with and without 1.4x and 2x converters)? I'm considering it for use with my 5d Mark III.
What do you think of the lens compared with the Canon EF 300 F2.8L IS II USM? Would also be great to see any in-depth reviews from a sports shooting perspective if anyone has seen any.
