8. Vignetting

First let's check the vignetting performance on the smaller APS-C/DX sensor – appropriate thumbnails, reached in crop mode with the help of the Nikon Z7 camera, can be found below.

The chances to notice vignetting you get only at the maximum relative aperture where that aberration reaches a moderate level of 24% (−0.78 EV). By f/2.0 it decreases to 19% (−0.62 EV), and by f/2.8 it becomes practically imperceptible, dropping to 10% (−0.30 EV).

After passing to full frame sensor there are far more problems and photos below show it pretty well.

At the maximum relative aperture you have to take into account a loss of as much as 57% of light in frame corners (−2.46 EV). In this area the tested lens fares weaker than its reflex camera equivalent but still it is better than the Tamron 1.8/35 and the Canon 2/35.

When you stop down the aperture to f/2.0 the vignetting is reduced but its level, 52% (−2.09 EV), remains high. You can notice it also by f/2.8 without any problems, with a result of 33% (−1.15 EV). A moderate level is achieved only by f/4.0 where that aberration amounts to 22% (−0.73 EV). By f/5.6 there's a slight decrease to 20% (−0.66 EV); further stopping down doesn't have any measurable influence on the aberration, described in this chapter.

Below we present averaged out values of brightness loss shown in concentric circles as you move further away from the frame centre. The numerical value of every image, expressed in percents, shows an area limited from the top and right by 100% and from the bottom by the presented curve. The area indicates how much light overall is lost due to the vignetting effect. Please, don’t mix these percentages with the values given at the beginning of the chapter because they aren’t directly connected
