[Brightcolours]

So... really the king of pincushion distortions... and not only in the longer half of the range. This is nucking futs. How do we call this "anti-fisheye"... the "frog-eye"? Actually, no, the "frog" theme is reserved to the Laowa brand, so I'm open to suggestions.

 

I don't know if evolution has figured out concave eyes?

My suggestion: oomph lens (vs fisheye lens). oomph being the sound one makes when being hit in the gut, which does create a concave belly for a moment.
