8. Vignetting

Let’s check how the lens performs in the vignetting category both in JPEG and RAW files, developed by independent software.

You don’t have to think about the vignetting at all while working with JPEG files. Already at the maximum relative aperture it amounts to just 18% (−0.57 EV) and on stopping down to f/2.8 it decreases to a level of 12% (−0.36 EV). What’s interesting, passing to the f/4.0 aperture makes that aberration decrease to 11% (−0.33 EV); only by employing f/5.6 you can see that problem disappear completely (7%).

Still only the analysis of RAW files, developed by independent software, is able to show the whole truth about the vignetting performance of the lens’s optics. In that case there are much more problems and it is especially visible at the maximum relative aperture where that aberration reaches 47% (−1.85 EV). On the one hand it’s a lot, on the other the result is hardly a surprise. Good f/2.0 aperture fastness and small physical dimensions – it couldn’t have ended otherwise. You get nothing for nothing…

When you stop down the aperture to f/2.8 the vignetting decreases to 29% (−1.01 EV) and by f/4.0 it falls to a level of 22% (−0.73 EV). Further vignetting drop along with the stopping down is slight. By f/5.6 that aberration reaches 20% (−0.66 EV) and by f/8.0 it amounts to 18% (−0.56 EV). Some chance to notice the light fall-off you get even by f/11 where it gets to 14% (−0.46 EV).
