Review of Sigma 10-20/3.5 HSM

Not in Pentax mount, but one of the more detailed ones I've seen.

Flare control is great:

Distortion is worse:

Vignetting is worse: (yeah, huh?? 82mm lens should have less vignetting)-:

Sharpness is center is better than the other ultrawides:

I don't see a reason to upgrade my older version...
