As long as you work with JPEG files the vignetting shouldn’t be especially bothersome. At the maximum relative aperture we saw light fall-off reaching 26% (−0.88 EV). Stopping down the aperture to f/2.0 changed almost nothing because the vignetting amounted to 20% (−0.63 EV). That aberration disappeared by f/2.8 and f/4.0 apertures, being respectively 12% (−0.37 EV) and 10% (−0.30 EV).

The problems start when you progress to RAW files. At the maximum relative aperture the losses of light are as significant as 49% (−1.94 EV) – that’s a lot. Still the rivals designed for smaller sensors such as the Canon 1.4/24L II, the Sigma A 1.4/24 or the Samyang 1.4/24 had the vignetting exceeding even 60%. The Nikkor AF-S 1.4/24 which was the best in this group, had a result of 54%, so a tad worse than that of the Fujinon too.
When you stop down the aperture to f/2.0, the vignetting decreases to 34% (−1.18 EV); a sensible situation can be observed by f/2.8 where that aberration decreases to 20% (−0.66 EV). Further stopping down doesn’t help much: by f/4.0 and f/5.6 we got the same value of 18% (−0.56 EV).
