After much debating over which lens to buy as a portrait lens, 100mm f2.8 L Macro, 70-200 f2.8 IS II, finally went and laid out the bucks for the 135mm f2 after much reading of reviews and viewing much eye candy of this lens and I have to tell ya I'M IMPRESSED!!!
The lens is as sharp as people have been reporting with the AF fast and accurate.
I have no hesitation in recomending this lens as a great portrait lens, if you have been sitting on the fence with this lens, dont, it is everything people have been saying about it, IT'S AWESOME. I have included a shot with the lens from today, only PP is an exposure adjustment, no cropping and no sharpening. Just a quick test shot.
