I was curious if that angle might have a little bit of "fisheye" look to it. Or if there have been any other quality issues with it.

Thanks for any help,

I've not heard or seen any video from one of those, and I wonder if it is really a different lens! We measure the AOV to be about 58.2deg. early in the thread based on the corner-to-corner distance of the image captured in a video frame and the distance of the camera from the object. But this is not necessarily the AOV published for a lens. Realistically, the lens AOV has to be bigger than the frame corner-to-corner distance by a good margin to keep vignetting minimized. I don't think there would be any significant fisheye effect with a 72 deg. AOV lens.

If any one has one of these "72 deg." versions, maybe you can post a video and comment on it? A wider AOV should reduce the vignetting we see with all the current videos posted here.
