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.
Thanks for the details, Tom. I've been needing a real #11 for a while so I just ordered the one I linked to. I'll post a sample when I get it (10-15 days or so).
