Anyhow, I agree that $1100 is quite pricey for the lens. Keep searching but the reviews seem pretty good about this one.
One should always cite one's sources, especially when dealing with a subjective topic like this.
Here is the quote from which I got my info..
"About a year ago, I was exhibiting the same LBA symptoms -- wanting a fast 70-200ish lens for candids. The choices that were presented at the time were:
Pentax FA*80-200/2.8 @ $1200+ USD used only -- obviously the best
Sigma APO 70-200/2.8 EX DG -- @ $800 new, $600 used -- very good, but not as good as the Pentax
Tokina 80-200 AT-X Pro AF II -- @ $400 used -- a good lens, but noticeably not as good as the Sigma or Pentax
I ended up settling for the Tokina -- It's good enough for my purpose, and the degree of softness doesn't really detract significantly for candids, mostly head shots of people who somehow don't appreciate brutal sharpness as much as I do . It's also the lightest of the three, but not by much -- it's still a handful to carry around and use (and pretty intimidating to human subjects). This is also a good FL range for zoos, but I'd like more sharpness than the Tok can deliver for this purpose -- especially for use with a TC.
If I had to do it over again, I'd probably get the Sigma, and if I planned on more significant use for this FL range, bite the bullet and search out a Pentax, but with the DA*50-135 coming soon, I'll be able to have a smaller, lighter, faster focusing, less intimidating lens to use for candids, so I'm pretty sure that I'll just stand pat with the Tokina. . . at least until a "deal that I can't refuse" comes along on a Sigma or Pentax. . .
Of course YMMV -- but that's part of the fun of LBA."

Sadly, as I stated, I do not have direct experience with any of these. I have only been reading and longing.....
