Hi!
I don't know her bodily features in person but it looks pretty standard, no abnormal distortions at all ;-)
Stunning to me that even the corners don't show visible distortions or blurrs. Behind which dome do you shoot this lens?
There's something to say about extreme WA and FE lenses. You have to get used to check the finder for things you don't want to see on the image. Your own dangling equipment e.g. or the tip of a fin of the diver next to you.
It took me some time to get used to the extreme (and unusual) perspectives (esp. topside) and to handle them. Once you get used to the lens it's an addiction. I own the Olympus 7-14mm (114° to 75° angle of view) with nearly no distortion at all, a masterpiece of WA design. I'm eagerly waiting for the 8mm FE (180° angle of view) that has been announced recently.
My UW experience with 180° FE comes from the Olympus E-20 with Raynox DCFR180PRO converter. Although this lens was housed poorly (in a bruder housing with a quite wrong positioned dome) the results were not that bad.
The wider the angle, the closer you can get. The closer you can get the more colourfull your pictures. I never ever missed zooming to less than 180°.
