Wonderful quality, one hundred percent satisfied!

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).

Pros

1. Light at all focal lengths (for zoom), hence fast focus in low light. 2. Sharp. 3. Durable. 4. Fast, quiet and accurate focus (I immediately tested it after reading reviews about front / back focus). 5. It is well assembled (compared to the tamron 17-50 2.8, which is very flimsy), the trunk is also blocked, although it does not seem to leave. 6. * working *, and not for show, a 4-stop stabilizer - you can take sharp pictures of static objects with a shutter speed of 1/2 - 1/5 s. 7. Pleasant bokeh. 8. Hood and case included. 9. 2 aspherical and 2 low-dispersion elements (for some reason, it is not indicated in the description on the market). 10. Price for quality. 11. Universal focal length 27 - 80mm (crop 1.6).

Cons

1. Only crop. 2. Too heavy - a feature of the assembly and large lenses, on carcasses of the 100d / 1300d level, I think it will greatly outweigh. 3. During autofocus, you cannot manually adjust (even absolutely impossible, as it can disable the focusing system). 4. Expensive 77mm filters (I don't use them, so it's not critical for me). 5. Distortions at the very edge are not uniform on all sides - I have a little more lather on the right, again, only visible upon closer examination on a test target. 6. In the off state, something shakes inside, but the instructions describe that this is a normal operating condition and is not a marriage, but a design feature of the stabilizer. At first it was scary), the battery also drains much faster with the stub, kenon did not notice this with lenses, now I turn it on when necessary. 7. I would like large focal lengths at least 17-70mm)), but this would add weight / size / price / distortion.
