I just learned yesterday that the 10.5 fisheye is basically the same lens as the 16mm fisheye (FX) and that the difference is due to the crop factor because the 10.5 is labeled a "DX". When I install my 10.5 on my D800 of course it knows it's a DX lens and shows the crop box accordingly. My question is: How can I take advantage of more of the frame in the D800? Is there a way to defeat the auto DX sensing and show more of the field of view in the D800?
I'll be playing with this today, but any assistance would be appreciated.

Not quite a full circle
The 10.5mm DX produces an image circle approximately 28mm in diameter, so if you cut the hood off and use it on an FX camera with DX Crop Mode turned off, you'll get an image with circular sides but straight top and bottom edges.
Tom, Where did you hear the two lenses are basically the same? The only thing the same is they are both fisheye lenses that cover 180˚.
The 10.5mm has a different lens formula, has CRC, has an ED element and focuses down to 1:5. The 16mm doesn't have CRC or an ED element and only focuses down to a 1:13 magnification.
And yes you can use the 10.5 on a FX body and turn the DX crop off but you'll end up with a very strange frame which has the shape of the lens hood in the picture. You are better off just using the lens in DX crop mode on your D800 and enjoy the photos. You will still get a 180˚ shot.
The 10.5mm f/2.8 DX fisheye is a much newer design than the older 16mm f/2.8 FX fisheye. The 10.5mm has a cult following in the world of spherical panoramas even when used on FX cameras. The hood is often shaved by FX users to allow more coverage on the FX sensor. This in turn allows a 360 degree spherical panorama with less shots. I'm not aware any real benefit of "shaving" when used in tradition photography. Yes it is time for a face-lift on the 16mm FX fisheye. The present lens is outdated!

I guess only shows it as an option when you use one or the other lens. If I didn't use the 10.5, the 1-click correction does not appear. I would assume the 16 works the same way... no 10.5 or 16 in the metadata, CNX2 doesn't give you the option. I have 2.3.0, BTW.
The reason I mentioned it is because only the 10.5 is mentioned in After The Shoot by Mike Hagen.
I hate when people ask me what I see myself doing in 5 years...... I don't have 2020 vision!

CNX2 only shows the option when a photo from one or the other is being processed, never both.
edit. I have both lenses and originally used the fisheye correction when I first got the 16mm lens in 2006. Back then it was Nikon Capture of various versions.
