HI, I was forced to buy the new canon 70-200 MK2 as my old one started to not focus. I looked down the barrel it was full of mold. I live in the sub tropics, canon said they couldn't fix it.
The new lens is mighty expensive but I never thought they could improve over my original 70-200 but they have. It is such a good lens I am happy but broke. Below is a link to some soundwave and metallica shots I took with it over they weekend. The other lens used was a 16-35.........cheers taojones
