8. Vignetting

When we tested other 4/3 system lenses on 4/3 reflex cameras the vignetting problems were rare indeed. In the Micro 4/3 system small lenses are its main advantage and, as they are positioned much nearer the sensor than in the case of other reflex cameras, such problems are much more pronounced. Let’s check how the Leica coped with it.

At the maximum relative aperture the brightness loss in the frame corners amounts to 39% (-1.43 EV), so it is distinct and easy to notice. On stopping down the aperture to f/4.0 the vignetting decreases to 24% and by f/5.6 it reaches 18%. This aberration becomes completely imperceptible by f/8.0 and by f/11 where it is 12% and 9% respectively.
