8. Vignetting

The Fujifilm X system cameras correct vignetting in JPEG files so we always test JPEG and RAW files at the same time. The Fujinon’s 1.4/23 level of that aberration can be assessed by glancing at thumbnails, shown below.

As long as you work with JPEG files the vignetting shouldn’t bother you at all. At the maximum relative aperture it amounts to 27% (-0.90 EV) and is moderate. After stopping down to f/2.0 it decreases slightly to 22% (-0.73 EV) and when you pass to f/2.8 it becomes imperceptible, reaching just 14% (-0.42 EV). On further stopping down you see only slight improvement – the vignetting gets lower by just 2%.

The RAW files are just another matter. The vignetting is distinct here, reaching at the maximum relative aperture as high as 50% (-2.01 EV). A noticeable decrease of that aberration is observed on stopping down to f/2.0 - the brightness loss falls to 35% (-1.27 EV). By f/2.8 and f/4.0 you deal with moderate level of vignetting, with the light fall-off in the corners being respectively 23% (-0.77 EV) and 21% (-0.67 EV). Further stopping down doesn’t bring any measurable effects.

Perhaps the results of the Fujinon 1.4/23 are not exactly impressive in this category but still you should remember that such an angle of view and f/1.4 aperture rise the standards quite significantly. It’s also worth remembering that most of full frame constructions of this type fare even worse, having 50-70% of vignetting at the maximum relative aperture.
