Nikon Nikkor AF-S DX 55-200 mm f/4-5.6G IF-ED VR

8. Vignetting

The lens without stabilization had weak results in this category. It’s younger brother doesn’t fare better. At 55 mm and by f/4.0 the corner light fall-off amounted to as much as 33% (-1.16 EV). On stopping down to f/8 the vignetting decreased to 19% but only by f/11 it reached an imperceptible level (8%).

In the middle of the focal lengths range the situation is even worse. By f/4.8 the brightness loss in the frame corners is as much as 38% (-1.37 EV) By f/5.6 it decreases to 30%, by f/8.0 it drops further to 12% and only by f/11 it becomes negligible (4%).

At 200 mm the results are not good either. At the maximum relative aperture the vignetting amounts to 37% (-1.35 EV) and by stopping down to f/8.0 it decreases to 20%. Only usage of f/11 makes the problem disappear completely (3%).
