Excerpt: I have had this lens only for a short while and so far it is taking lovely pictures. Where there are problems, it is clearly operator error--takes some getting used to because it's very different from what I was using before. I have some vision issues that make focusing on manual tricky.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Strong Construction
Excerpt: I use it with my Pentax K3 II. It is a tad bit slow on autofocus but nothing that bothers me too much. I'm not doing action shots with it. I'm finding that the focus seems a bit soft on some of the shots but that might have more to do with the photographer than the lens.
Pros: Durable, Easily Interchangeable, Lightweight, Rugged, Strong Construction
Excerpt: I'm using this with a GH4/Canon EF SpeedBooster combo and overall I'm very pleased. I haven't noticed any crazy chromatic aberration. There IS some vignetting when shooting at the widest focal lengths, but it's really nothing to write home about.
Pros: Consistent Output, Durable, Nice Bokeh, Strong Construction
Summary: Wonderful lenses... Mine came all dusty though. I was looking at the glass and noticed that the lenses has very tiny scratches - as if someone tried to clean it with any sort of cloth. I took some shots and I can't see any imperfection. Hopefully this won't become a big deal in the future
