Yes, those were my images. I had tested the 14-24 on a Sea&Sea housing and the 8" glass port several months back. Maybe it was the wrong port extension, but I could not get acceptable corner sharpness out of this setup. A couple weeks ago I was in the Bahamas giving the Aquatica 9.25" megadome with the 14-24 a good working out at various settings. f/5.6 produced a decent image, albeit with a little corner softness, and at f/8, the images seem to be what I would consider acceptable in way of corner sharpness. And in comparison, using the 16mm fisheye, I didn't notice any significant softening in the corners.
