Comparison # 89
Lens Sharpness Comparison
Sigma 10-20 F4-5.6 vs. Tokina 11-16
Sharpness at 16mm. Tested Apertures F2.8/F5, F6.3, F10/F11
	Comparison by Sinan Ozturk

Both lenses are set to 16mm for this test.

In the first comparison both lenses are in their widest aperture which is F2.8 for Tokina and F5.0 for Sigma. At this comparison Sigma seems to be doing better. Tokina has some vignetting and also softer in the corners while their center performance is close.

When they are both stopped down to F6.3, Tokina's vignetting improves and now Sigma's vignetting looks heavier especially in the corners. Yet its sharpness also looks a little better than Tokina, especially in the corners while centers looks very same.

Stopped down further, their performance gets more closer to eachother. Its not easy to decide which photo is better in the third comparison so I'll leave the decision to you. [Review by Sinan Ozturk]
