Lens Comparison
Sigma 10-20 F4-5.6 vs. Tokina 11-16
at 11mm. Their widest focal lengths at F8
	Comparison by Sinan Ozturk

Both lenses were set to F8 and their widest focal length. This is 10mm for Sigma 10-20 and 11mm for Tokina 11-16. So this shows that 1mm difference between 2 lenses in close shot.

At this aperture I found the lenses' performance similiar. Sigma seems to have a little more contrast so its photo looking very slightly better to me. Their center sharpness performances looks similiar but due to more contrast Sigma looks a little more crisp in the center. On the other hand Tokina's corner/edge sharpness is better.

As we concluded in Comparison #52 [Tokina 11-16 vs Sigma 10-20], Sigma's corner performance peaks at F16 so in F8 its falling a little bit behind of Tokina.

Both shots are handheld. [Review by Sinan Ozturk]
