Lens Sharpness Comparison

Tokina 11-16 vs. Sigma 10-20 F4-5.6

Sharpness at 11mm.
Tested Apertures F2.8/F4.5, F5.6, F11, F11
 
Comparison by Sinan Ozturk   
Lenses were tested at 11mm with tripod.

In the first comparison they are in their widest apertures which is F2.8 for Tokina 11-16mm F2.8 and F4.5 for Sigma 10-20 F4-5.6. At this aperture Tokina seems to be doing better in the corners while center performance is pretty close. Tokina has a little bit more vignetting in this comparison.

When both stopped down to F5.6, Tokina's vignetting cures and now Sigma has more vignetting than Tokina 11-16mm F2.8. Tokina also looks sharper both in the center and especially in the corners.

Sigma improves itself in F8. They are now close but Tokina is just a tad ahead especially in the corner performance. Same can be said for F11.

In the last comparison I set Sigma 10-20 F4-5.6 to 10mm so you can see what's the difference you gain with Sigma 10-20 F4-5.6's 10mm focal length against Tokina 11-16mm F2.8's 11mm.
