I owned this lens for a long time, got it for under $400 (like $350 I think), sold for almost $900. Miss the lens, but $900 was toooooooooooooooooooooooooooooooooooooooo much to turn down. Buy low, sell high!!!
Actually I'd have made more but Ebay pulled my listing because I violated a rule I didn't know I was breaking, all they had to do was give me 8 hours notice to change it or something, and I've have changed it. Similar lenses in similar shape sold for over $1000 the days/weeks before. That is the last time Ebay will screw me, I now sell everything on Craigslist, for less money, but also less ebay cut of course.
Anyway, it is sharp, even wide open (though not as sharp). It's built like a tank. It does suffer from purple fringing on the older 6MP cameras, a bit less on the 10MP, but still there. It can be corrected in post processing.
My recommendation, buy the Tokina, sell it on Ebay, and buy whatever you want!
