The light fall-off in the frame corners is visible at the maximum relative aperture, amounting there to 26% (-0.85 EV). That aberration disappears almost completely by f/2.0, reaching just 9% (-0.29 EV).

Still it’s full frame which is the biggest challenge for 1.4/35 lenses. Thumbnails below show how serious a challenge it is.
At the maximum relative aperture the vignetting of the Sigma is monstrous, reaching 66% (-3.16 EV). Only the Canon fares here worse, the Nikkor is a tad better and the Zeiss, the Samyang and the Sony – much better. On stopping down the aperture the Sigma’s performance improves, though. By f/2.0 the vignetting is 44% (-1.69 EV) so the tested lens is better than the Canon, getting the same result, within the margin of error, as that of the Nikkor and the Sony. Still it loses out to the Zeiss and the Samyang (which, by the way, are physically the biggest instruments in this class of equipment). By f/2.8 the vignetting is still visible, amounting to 24% (-0.79 EV). Only by f/4.0 and f/5.6 you might forget about this aberration because in their case it reaches just about 15%.
