8mm circular fisheye - this is what comes out

[tikkathreebarrel]

Just spent a weekend playing with my new toy an 8mm Sigma f4 fisheye lens. I'm far from having fully fathomed it but if you were wondering what comes out and what you can do with the images, I hope these three will be informative. I have since learned other stunts like laying on my back and shooting straight up to get, in effect, the insider of half of a sphere.

Firstly, as uploaded from the camera and simply converted RAW to Jpeg

Secondly, cropped

Thirdly, distortion removed.
