A very good Always-plan

As a photo enthusiast, I prefer to photograph it with fixed focal lengths - image quality is very important to me. Unfortunately optically good and fast lenses are very large and heavy, and have in situations where you can carry around only the minimum amount of weight with it and wants to stay at home (on vacation, on long hiking and biking trips, etc). Looking around for an ever-top, I did not necessarily cover the largest focal length range. My Zeil, it was to sacrifice a little on the light intensity and just a little bit of the image quality, but to obtain an objective that for landscapes / architecture is just as suitable as for frame-filling portraits. And exactly this description corresponds to the Sigma 18-125. Unlike many super-zoom changes the focal length range is kept within limits, but only a little picture quality has to be sacrificed. If I'm honest, it's amazing how sharp the Sigma is the whole area above. A push, especially one in this price range, I would not have expected. The single optical Macke, I could find - and I really wanted seeeeeeehr long and detailed - is the vignetting at wide angle when shooting wide open. Although not critical - as I have also experienced far worse - but it is definitely worth a stop down aperture. Otherwise, as I said, the focus is more than good. Distortion moderately and regularly, and therefore very easy to fix in EBV. Chromatic aberrations keep within limits.
It is also gratifying that the lens, although only 250 expensive, no plastic bomber is. It feels surprisingly solid, and the rings have the typical "Sigma EX" Finish. The AF works fast and accurately and the stabilizer brings 1 to 2 aperture.
I got to the Sigma 18-125 in some areas even more for my money than I would have expected, and would definitely buy the lens again. I would recommend it to anyone who is looking for a good lens, for all the situations in which the expensive and heavy prime lenses must stay at home.
