Here they wrote about some kind of "wild chromatism". They must have been badly built. Something, but the chromaticity here is quite moderate (I always shoot in RAW). In general, the difficulty of writing a review for this device is the search for flaws. Objectively, there are almost none. Subjectively, for example, I would like a staffer a little wider (mm 28-31), maybe a little more raisins in the bokeh. But, in fairness - a very successful universal lens.
