thanks Mike.

a friend of me want to buy this big sigma and he is using canon 7d.

we tried the lens on 7d.

af is pratically perfect without kenko1.4 dgx pro.

still good with kenko but not as fast as on 5dmk3.we tried with very good light conditions.

he is actually using canon 300f2.8 Is1 +canon tc x2 modelII

tonight he will study the raw made comparing with the same targets got with canon 300.

i will let you know about file quality very soon
