Vignetting is one of the aberrations which were supposed to be almost totally eliminated by using the Four Thirds system. However, the ZD 50 mm Macro model had a measurable level of it as, at the maximum aperture, it amounted to19% (-0.62 EV). On stopping down by one exposition value stop though, the vignetting becomes practically imperceptible (3%). What’s interesting, the Olympus F Zuiko, designed to work on full frame, behaves almost identically. At maximum aperture the vignetting reaches 18% (-0.58 EV) and on stopping down to f/2.8 it decreases to 5%. In this category and in the test conducted on a small 4/3 sensor it is difficult to distinguish between these two lenses.
