Sigma 30mm F1.4 Lens Test Results
Sigma 30mm f/1.4 DN vs. Zeiss 32mm f/1.8 vs. Sony E 35mm f/1.8
From DxOMark conclusion :
The Sigma 30mm f/1.4 DN is an excellent standard prime option for Sony E-mount cameras and ranks at the top for all lenses we’ve tested on the A6000. Sharpness is outstanding, delivering excellent center resolution at all aperture settings up to f/8, with only minimal drop-off in the corners. Vignetting is pretty heavy at f/1.4, as the lens struggles to achieve the same intensity of light across the large APS-C sensor at its maximum aperture. But it improves greatly by f/1.8 and is all but eradicated by f/2.8. The Sigma version is both sharper in the center and more consistent across the frame. Add to that the faster maximum f/1.4 aperture, and the $339 price tag it looks to be a very attractive standard prime option for Sony mirrorless photographers.
