At the maximum relative aperture brightness loss in frame corners reaches a level of 55% (-2.31 EV). It is a significant value but still acceptable, especially if you take into account the aperture fastness of the Argus. By f/1.1 vignetting decreases to 50% (-2.02 EV), and by f/1.4 it drops even further to 37% (-1.33 EV). By f/2.0 and f/2.8 you deal with a bit more moderate vignetting levels, with results of 27% (-0.91 EV), and 22% (-0.71 EV) respectively. Problems end by f/4.0, f/5.6, and f/8.0, where brightness loss levels are, respectively: 18% (-0.57 EV), 13% (-0.40 EV), and 12% (-0.38 EV).

The overall reflection is such that, for contemporary mirrorless standards, the Laowa Argus 0.95/33 deals with vignetting decently well even though it doesn't offer you excellent results in this category.
