if you got the $$$.. go for the 400f2.8........
if you compare the 300f2.8 plus x2 and a 600f4... there must be a difference.. but I not into birdie or sports.. so unlikely to invest in those in the near future.. LOL... haven't even done marco yet (at least not in my recent memory)...
You tried the 400 2.8 before? I know will have difference between real 600 and combo-ed version.
