Nikon Nikkor AF-S DX Micro 40 mm f/2.8G - Vignetting


It can be noticed that at the maximum relative aperture the vignetting is quite significant. It is a bit strange – after all the lens is neither small nor fast. The measurements show that in the corner of the frame as much as 39% of light (-1.43 EV) is lost. The situation improves by f/4.0 where the vignetting is 22% (-0.71 EV). That aberration becomes imperceptible only by f/5.6 where it reaches the level of just 9% (-0.28 EV).
