8. Vignetting

First let's check how vignetting looks on the smaller APS-C sensor– appropriate thumbnails you can find below.

In this case you get some chances to notice vignetting only at the maximum relative aperture, where its value amounts to 32% (−1.13 EV). By f/2.8 it decreases to 13% (−0.41 EV), and by f/4.0 it is 12% (−0.37 EV).

After passing to the bigger, full frame sensor there are far more problems and they are clearly visible in the following photos.

At the maximum relative aperture vignetting reaches a huge level of 65% (−3.05 EV) and it is the first serious stlip-up of the tested lens. As a kind of consolation you might add that the Sigma C 2/35 fared even weaker but the Battis had a better result of 55%. What's curious, a bit faster Sony FE 1.8/35, when stopped down to f/2.0, showed a level of 66% so, in fact, the same as the Voigtlander at its maximum relative aperture. The Samyang 1.8/35 doesn't fare better as its vignetting by f/2.0 amounts to 63%. As you can see, in this category the performance of all lenses is similarly weak.

Still it is a bit consoling that, at least at the very beginning, on stopping down the aperture the Voigtlander manages to improve its performance quite quickly. By f/2.8 vignetting amounts to 47% (−1.83 EV), by f/4.0 it decreases to 32% (−1.12 EV), and by f/5.6 to 30% (−1.02 EV). Further stopping down doesn't have any measureable effect on the aberration, described here.
