At the maximum relative aperture you have to take into account the loss of 38% (−1.37 EV) of light in the frame corners. It is not a result to be proud of but also nothing to be ashamed of. It is more worrisome that the vignetting decreases quite slowly with the stopping down. By f/4.0 its value reaches 24% (−0.81 EV), and by f/5.6 it is 17% (−0.39 EV). Even by f/8.0 you get some chances to notice it as we got a value of 13% (−0.39 EV).

The vignetting is by 1-3% higher for RAW files and it is mainly a result of a bit wider field of view, leaving some margin necessary for the distortion correction done by the software of the camera.
