8. Vignetting

First let’s deal with the vignetting on the smaller sensor of the Nikkon D7000. Appropriate thumbnails are shown below.

No problems here. At the maximum relative aperture the vignetting is moderate, reaching 24% (−0.81 EV). The aberration disappears completely by f/2.0 and f/2.8 where it is respectively 8% (−0.25 EV) and 4% (−0.11 EV).

Now let’s check what’s happening on the much more demanding full frame.

Truncated circles of light from the previous chapter didn’t allow us to harbor any illusions as to observing any outstanding results in this category. On the other hand, taking into account interesting parameters of the tested lens, the results are not so bad. At the maximum relative aperture the light fall-off in the frame corners amounted to 47% (−1.83 EV) and you can hardly call it high, especially when you compare it to the results of other fast portrait lenses. On stopping down the aperture to f/2.0 you can reduce the vignetting to 30% (−1.04 EV). By f/2.8 and f/4.0 you already deal with a slight level of that aberration and the values we got in our measurements were respectively 17% (−0.55 EV) and 14% (−0.42 EV). The problems end completely by f/5.6 where the aberration reaches just 10% (−0.30 EV).

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 expressed in percents for every image shows the area limited from the top and right by a value of 100% and from the bottom by the presented curve. The area shows 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.
