8. Vignetting

It is not easy to measure vignetting in a ‘fisheye’ lens so we are not able to give you a precise value. Still you can make a rough estimate. It seems that at the maximum relative aperture the brightness loss in the frame corners can reach near 1.7EV (so about 45%). The Samyang 3.5/7.5 designed for the Micro 4/3 systems was better but firstly it was a slower construction and secondly, it was supposed to work with smaller detectors on which correcting the vignetting is easier.
