Sony 50mm 1.8 vs. Sigma 50mm 2.8 Sharpness Comparison (at 50mm.)

Comparison # 66
Lens Sharpness Comparison
Sony 50mm 1.8 vs. Sigma 50mm 2.8
Sharpness at 50mm. Tested Apertures F1.8/F2.8, F2.8, F4, F8
	Comparison by Sinan Ozturk

First comparison is the lenses widest aperture: Sony 50mm F1.8 vs. Sigma 50 2.8. Sony is pretty weak in F1.8, its not as sharp as Sigma's F2.8 and more importantly vignetting is very heavy at F1.8. However it can still at least go as wide as F1.8!

In the second comparison we stop down Sony to F2.8 too so now both lenses are at F2.8. Sony's vignetting improves dramatically at F2.8 in some much that now Sigma has more vignetting than Sony at this aperture. Their sharpness at F2.8 are very close but if you need to pick one, I guess we can say Sigma is very very slightly more sharp at F2.8.

I can we can say the same for F4. Both lenses has a good sharpness and vignetting control but still Sigma is very slightly sharper and Sony has slightly less vignetting at F4.

At F8, Sony 50mm makes a leap though. Its sharpness improves and now its more sharper than Sigma 50mm at this aperture. Their center sharpness performance are pretty close but Sony has an edge in corners. Sigma is still quite sharp but just not as sharp as Sony in the corners. As for vignetting both lenses control it quite well in F8 but if we have to pick a winner for vignetting, I guess we can say Sony 50mm 1.8 has slightly better control in vignetting and produce more bright photos at F8. Yet I don't know if this can be an excuse for its dismaying vignetting performance at F1.8. [Review by Sinan Ozturk]
