When it comes to JPEG files with distortion correction switched on (but without adding vignetting correction) brightness loss in frame corners at the maximum relative aperture amounted to 26% (-0.88 EV) and you can call it moderate. That value decreases to 16% (-0.51 EV) on stopping down the aperture to f/4.0 and to 15% (-0.47 EV) on stopping down to f/5.6.

Vignetting values are a big higher for neutral RAW files. In the case of maximum relative aperture you have to take into account vignetting of 30% (-1.03 EV), and it decreases to 20% (-0.63 EV) on stopping down the aperture to f/4.0. By f/5.6 and higher apertures this aberration reaches 18% (-0.58 EV).

You can notice differences between JPEG and RAW files also on full frame but they aren't very conspicuous. The camera body doesn't correct vignetting automatically for JPEG files, it corrects distortion and then crops images slightly.
In case of JPEGs and the maximum relative aperture brightness loss in frame corners amounts to 57% (-2.47 EV) and decreases to 41% (-1.54 EV) on stopping down the aperture to f/4.0. By f/5.6 vingetting decreases to 35% (-1.23 EV) and then it stays on that level no matter how strong you stop down the aperture further.
When it comes to RAW files by f/2.8 we got a result of 58% (-2.53 EV). It's a lot but, taking physical dimensions of the tested lens into account, it would be difficult to expect other performance in this category. By f/4.0 vignetting decreases to 46% (-1.79 EV), and by f/5.6 - to 40% (-1.47 EV). Further stopping down doesn't produce any measureable effects in this area.
