+ It's surprisingly easy to operate with a manual lens, no undefined Rumgedrehe the focus ring as with the other competitors. For me the scans like landscapes, F8, focus on just before make infinity and is good (if one takes to stop, the foreground is slightly out of focus)
+ Very valuable process, it weighs a little less like my Tamron 18-200 but much more like my other lenses. But it is not too heavy.
+ Picture quality when viewed subjectively, it is much sharper as my Tamron and similarly sharp as my SEL35f18. Pleasant color.
neutral:
o the stop is infinity not quite right, the line before is correct.
o some reviews complain chromatic aberration, so I could not even find disturbing, in my opinion, it has less like my Tamron.
o distortion, the lens recorded easily. But for me, at least in a tolerable range, similar to my 19mm Sigma.
Negative
- Flares in accordance with unfavorable lighting conditions.
Overall I am very satisfied with the purchase, who knows the problems of manual focus in E-mount cameras in conjunction with autofocus lenses, here gets a good solution for landscape photographers.
If I could wish for something, it would be a stabilization. In poorly lit rooms, if I do not stand here, I use my dear SEL35f18.
