Already using the Nikon 12-24 and 10.5 fisheye distortion corrected with Capture NX2, I wondered if this would hold ultra wide-angle comparison with the 10.5 fisheye corrected with NX2. I'm not disappointed, this extraordinary lens possesses a superb image quality and virtually no distortion. Its very short focal length opens up new possibilities in real time without having to resort to distortion correction of a fish-eye lens. Superb object that I recommend for fans of small focal lengths.
