8. Vignetting

High vignetting is often a big problem for the universal Nikon zooms. Unfortunately, the Nikkor 18-105 VR is not an exception to the rule. At 18 mm and f/3.5 the illumination loss in the frame corners reaches as much as 43% ( -1.62 EV). By f/4.0 the level of this aberrations decreases to 37% and on stopping down by one stop it falls to 23%. Only by the relative aperture of f/8.0 the vignetting comes near an imperceptible level of 10%.

The situation is a bit better in the middle of the range. At 35 mm and wide open the vignetting amounts to 35% ( -1.25 EV); by f/5.6 it decreases to the level of 22%. At f/8.0 it’s still noticeable (14%) and only at f/11 it drops below 10%.

At 70 mm and f/5.3 the frame corner illumination loss reaches as much as 43% ( -1.64 EV). Fortunately, the result is better by f/8.0, where vignetting decreases to 19% and becomes completely unobtrusive by f/11, where it is just 9%.

The worst situation we’ve noticed for the maximum focal length. There, by f/5.6 the vignetting level is very high and reaches 52% ( - 2.1 EV). On stopping down by one stop it decreases to 28% and by f/11 it disappears almost completely (10%).
