In case of JPEG files the situation looks sensibly well. At the maximum relative aperture vignetting reaches 38% (−1.38 EV), a decent result for these parameters, rather difficult to correct. By f/1.0 you see 36% (−1.30 EV), by f/1.4 it decreases to 26% (−0.87 EV), and by f/2.0 it reaches18% (−0.48 EV). By f/2.8 and f/4.0 we got, respectively 14% (-0.44 EV), and 9% (-0.28 EV).

Uncorrected RAW files can tell us more about the real level of the aberration, described here. The results are higher – at the maximum relative aperture you have to take into account loss of light reaching 52% (−2.10 EV). It's a lot but you still have to remind yourself with what aperture fastness you're dealing with. Anyway I wouldn't complain too much.
By f/1.0 vignetting decreases to 49% (−1.97 EV), and by f/1.4 to 38% (−1.39 EV). By f/2.0 you have to tolerate a loss of light reaching 29% (−0.98 EV), and it drops even more to 23% (-0.76 EV) on stopping down the aperture to f/2.8. By f/4.0 and f/5.6 relative apertures we got a results that amounted to, respectively, 17% (-0.55 EV) and 14% (-0.41 EV).
