On the A6000 is equivalent to a 12mm lens, and the viewing angle is likely to amount to nearly 180 degrees.
Of course, the distortion is enormous in the picture, but so that's just the fish eye.
If you hold the camera perfectly straight, you have a straight horizon line and can take great landscape photos.
At aperture 8 infinitely everything is from 30cm to almost sharply, hence the lack of autofocus is to get over.
The sharpness is impressive, from the center to the edge is the picture quality impressive.
My absolute favorite lens.
