The optical power exceeds my expectations. Here beat in my chest two hearts: Firstly, I like taking pictures with super sharp lenses (Canon 50mm and 60mm macro) on the other hand I love Super zooms to spontaneously hold each scene can (Canon 18-200mm or 18-270mm Tamron). The Super zooms are just in high focal lengths "soft", the Tamron 270mm is in a catastrophe. Similarly, "soft" image quality I had expected from 18-135, especially the older variant had (without STM) get no particularly good reviews. Here me the 18-135 STM pleasantly surprised: The sharpness of the lens is really good! The other optical parameters are ok (at Photozone.de can it be beautiful - even in comparison - look). The focal length range is also enjoyable and enough for a lot of spontaneous images. In Ww it's enough for me, push one can never have enough ...
Processed it is good. It touches his good and high quality. It even has a "lock-slide", the lens might not have needed. The set zoom persists in every corner and does not slip. The missing lens hood is a nuisance again at Canon. Luckily, there are good alternatives in the meantime to the original. I am happy with Profox LH73B for 9.99.
For the price a sensational lens.
