Well I was gonna get the 100 mm macro by canon and the 70-300, but someone pointed out, don't really need a 70-300 with a 70-200 coming, so I am opting for a tokina macro (got great reviews) and this sigma or the tokina alternative...but I need opinions on how good they are.
The tokina and sigma both seem to get good reviews...
So, I would end up with
28-135 IS
70-200 f4 L
100mm tokina macro
120-400mm sigma
