Tokina AT-X 287 AF PRO SV 28-70mm f/2.8D

[John Taylor]

Does anyone have the Pentax version of this lens? I'm wondering how  
it compares to the much more expensive and heavy Pentax FA 28-70  
F2.8. The Photodo rating for the Pentax is 3.5 compared to a 3.1 for  
the Tokina. I've had my eye on the FA for some time now, but for its  
price I could get an FA 24-90 plus maybe a couple others on my list  
(16-45, 50-200, etc).

Thanks,
