8. Vignetting

Let’s check how the lens performs in this category in JPEG files and in RAWs developed by independent software.

Although the lens correct the vignetting in JPEG files you can still notice it at the maximum relative aperture as it amounts to 28% (−0.93 EV). Even by f/2.8 it would be difficult to call its level low as it still reaches 20% (−0.63 EV). The problem becomes negligible only by f/4.0 and f/5.6 where it decreases to 12% (−0.36 EV) and 9% (−0.27 EV) respectively.

In RAW files, however, the vignetting shows its true colours. At the maximum relative aperture you have to deal with brightness loss amounting to as much as 56% (−2.35 EV) in frame corners. It is a high value, partially stemming from small dimensions of the lens. Even the Fujinon 1.4/23 at its maximum relative aperture had a better result.

That aberration is still visible pretty well by f/2.8 where it reaches 40% (−1.49 EV). Only by f/40 and f/5.6 it diminishes to moderate values, 28% (−0.94 EV) and 24% (−0.80 EV) respectively. Further stopping down decreases the vignetting only by 1% at most.
