We didn't expect any miracles here, taking into account the parameters of the tested lens and its dimensions. Indeed, there are no miracles. By f/2.0 vignetting reaches a huge level of 69% (−3.41 EV) and it decreases to 55% (−2.34 EV) on stopping down the aperture to f/2.8. You won't have any problems with noticing this aberration even after a more significant stopping down. By f/4.0 it is 49% (−1.93 EV), and by f/5.6 it remains still high, amounting to 46% (−1.81 EV). Further stopping down doesn't produce any measureable effect.
