Lens Sharpness Comparison

Sony 50mm 1.8 vs. Sigma 17-70

Sharpness at 50mm.
Tested Apertures F1.8/F4, F2.8/F4, F4, F8
 
Comparison by Sinan Ozturk   
I guess we all established how Sony 50mm 1.8 doing against Sigma 17-70 F.2.8-4 at 50mm but more comparisons means more accurate conclusions so here is another one.

In the first comparison, lenses are at their widest aperture. This is F1.8 for Sony 50mm and F4 for Sigma 17-70. Sony 50mm's infamous F1.8 vignetting there but due to point of view in these photos its not very apparent in this comparison. But believe me its actually there! :) Despite the vignetting, corner sharpness is still significantly better in Sony 50mm. As for center sharpness I guess they are again tie.

In the second comparison Sony is now F2.8 and it dramatically improves in every field. Its vignetting is much better (let's say on par with Sigma), its sharpness is better both in corners and center.

When Sony 50 is also stopped down to F4 and compared to Sigma 17-70 at F4, Sony again takes over in all fields just like it did in Comparison #71 [Sony 50mm 1.8 vs. Sigma 17-70 F.2.8-4]. Sony's vignetting is now gone in F4 and it produces such a bright photo that now your eye catches Sigma's vignetting which we didn't notice in the first comparison. Sony is also far ahead in sharpness at F4. Its center sharpness is better than Sigma's and its corner sharpness is very dramatically better.

When both lenses are stopped down to F8 in the third comparison, Sigma 17-70 improves. Now its vignetting is gone and it also matches the center sharpness of Sony 50mm (or at least comes very close). Yet Sony is still significantly better in corner sharpness at F8.
