I was afraid to take not kenon after reading and seeing enough tales on the net), I went to a photo store with the thought: I’ll take a look, twist it in my hands, test it - I wasn’t going to buy it, in the end I have it) and I don’t regret a bit. In comparison with the 18-55 whale, the sky and the earth were also compared with the 18-135 STM canon, both are much darker, especially at 50mm (more noise or shutter speed from here), the whales are also less sharp throughout the range, the edges are approximately equally soft. Sharp starting from 2.8 at all focal lengths (17mm softer), not counting the edges of the frame - which is natural for the class, but it is noticeable only on test charts, you need to look very closely at real photos, when you cover the aperture, distortions completely disappear. I was pleased that it has profiles for auto-correction of distortions (chromatic, vignettes and distortions) in kenon carcasses i. E. full support (although turning it off, I didn’t notice much distortion), claims to be a semi-professional level in terms of picture quality and assembly, the most popular focal lengths for a non-narrow-profile photographer. The closest analogue in quality costs 2 times more expensive - Canon EF-S 17-55mm f/2.8).
