What I noticed positive:
1. The vignetting and blurring criticized are really negligible. If I, the three menu items point Lens Comp .: shade, chromatic aberration and distortion on automatic at my Nex 7, the quality is really very good.
2. Even without this setting brings the lens a good quality. The shadowing is there already in the corners, but honestly, they give the picture a good feeling of touch. Not for nothing 7 effects such as toy camera built into the Nex which enhance this effect even again. I like this kind of photography. Pictures get a lot more warmth and expressiveness as a totally ironed into the corners radiant bright illumination. That's my attitude towards it and those like me who want the same, I can only guess. Buy!
3. The quality of the workmanship is very good. Nothing wobbles or crunches the focus ring.
4. There is the possibility of two additional conversion lenses from Sony grow. The Sony VCL-ECU1 (makes the 16mm a 12mm lens) and the Sony VCL-ECF1 Fisheye (makes the 16mm lens a 10mm) .I have the latter ordered the same. It's very difficult and makes the whole thing a full-blown affair. Especially for special photograph or video mode, this combination is very suitable. Just attached the camera to the inner windshield of the car with a suction cup and filmed the ride. Since each Actioncam pales in nowhere. Great video quality that you get there.
Neutral Rating
1. A lens hood is not included. But from Setobjektiv SEL-1855 can use. The fits.
2. Unfortunately, there is no image stabilization. But the small compact design with 16mm and better light intensity are for me image stabilization enough.
Negatives can I report nothing. Unbeatable for the price. Have not yet repented.
Hope I could help a little.
