I got a 70-200f4L. My copy is razor sharp. Each shot i took with this lens really made me in love with it.
But, i'm dreaming of f2,8. I'm afraid of getting a bad copy of f2,8. Switching from a good f4 to a bad f2,8 would make me sick. Is there such a risk or f2,8 version is really far better than f4 ?
I think i don't need to jump for the IS version but in case if, i would have the same dilemna.
Please help me guys
