Here is Lis, flying our stunt kite. Extreme field of view (and curvature) due to 10.5mm fisheye lens.
Bonus photo: a beautiful shot taken by Kat, with my 500mm mirror lens, from the bow of her B&B sailboat.
I love how the extreme focal lengths (at opposite ends of the scale) are what made these two shots possible, by capturing something different from what the human eye sees.
