Perfect to Sony A6000

The lens consists of a mixture of glass, metal and plastic, but feels this surprisingly high at. Visually this falls on the red ring I pers. Attractive feel than the Canon L lenses.
Size and weight are very low, which is reflected in a system camera like the Sony A6000 or a Fuji X-E2 naturally very pleasant. The Sony therefore fits comfortably into a jacket pocket. Sony incl. Lens weigh about as much as my own Canon 17-35mm lens ...
The lens hood is included, allowing it to turn off the camera and lens on the lens, which I appreciate very much and almost always do.
The setting of the aperture values ​​is perfect (for me). Smooth enough that you can make it when you look through the viewfinder, but not as easy as with most Fuji lenses - you rarely adjusted accidentally.
The lens has no autofocus, no image stabilization and the set aperture values ​​are not transferred to the camera. Lightroom displays two dashes. That will not be a problem for most of you, for me during the test course already, but it requires a little discipline to keep that in mind if I took a picture on Aperture 2.8 or 4.
In a system camera focusing is not a problem. Thanks Focus Peaking one sees well, which area is sharp and ultra wide-angle focal lengths Tiefenunschärfe is anyway more of a side issue. Unfortunately evident at close range but the very generous display of the Sony A6000: It is often not clear what is now sharp and you have to take a closer look to it. OK in plants macro shots on tripod, not OK with people. On the other hand, wide-angle close-ups of people are not necessarily recommended, or, possibly not attractive.
Side note: ask Distance to 1m, aperture 4 and outside of macro is the whole world in focus. Easy may not be taking pictures and can trigger faster no camera, because the focusing is eliminated.
I am not a pixel peeper. For me, the look is more than adequate. She is very sharp in the middle, OK already at f 2.0. At 100% you see weaknesses, also in the center, but only there. The edges are generally a little weak, but show me a 12mm lens in which this is not the case! In Aperture 2.0 Aperture 4 from the vignetting is highly visible (that's normal), virtually gone. And of course they can be corrected in Lightroom / Photoshop.
Flair is considered a wide angle lens under control.
The only "flaw" is the illustration of stars at closed aperture. Yes, there is a star, but nothing, which is why you would jump for joy, right?
