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.

    The issue with the Sigma 30mm F1.4 DC DN is not the image quality but the challenging manual focus system. It is fine for photography but if you are hoping to use it for manual focus in video, it is nearly impossible to use. The manual focus does not move in proportion to the throw you give on the lens but rather ramps the throw based on the velocity you move the ring. You can move the focus ring very slowly and the focus will not change. But if you whip really quickly a short distance the focus will change dramatically. This behavior makes standard video techniques like “follow focus” nearly impossible. It is also VERY challenging to manually set critical focus in “run and gun” situations. The lens is great for photos and the auto focus is very good but manual focus for video is unusable. https://www.youtube.com/watch?v=Zn6VoOv_4Pw
