Lens Sharpness Comparison

Carl Zeiss 24-70 vs. Sigma 12-24

Sharpness at 24mm.
Tested Apertures F2.8/F5.6, F5.6, F8, F16, F16
 
Comparison by Sinan Ozturk   
In this comparison Carl Zeiss 24-70 F2.8 Ssm is in its wider focal length and Sigma 12-24 F4.5-5.6 Dg is in its narrowest which is 24mm.

First comparison is with lenses widest apertures in this focal length which is F2.8 for Zeiss and F5.6 for Sigma. Second comparison is F5.6, third F8, fourth F16 for both lenses.

In the last comparison I set Sigma to 12mm to show how much wide it can go in comparison to 24mm in the same location.
