Recently I found people shaving the lens hood off their Nikkor 10.5mm Fisheye which is a DX lens to use it on a full-frame Nikon DSLR. The result is a wider field-of-view but not even completely circular, more like a wheel-barrel.

What are the advantages of this? Why not just buy a Nikon-mount Sigma 8mm Circular fisheye instead? Or just get a rectangular full-frame fisheye? Has anyone seen how panorama software angle these types of images?

The lens warranty goes void and the damaging is permanent.

I do not shoot FF, but for example the Samyang 8mm fisheye is APS-C/DX only. But because of the price and quality, the FF users often decide to buy it and shave the hood. –  Juhele Apr 26 '12 at 5:31

Apparently Nikon currently only offers a 16mm fisheye for the FX cameras. I suppose "gaining" 5.5mm and "saving" $150 by modifying the DX is more than enough justification for some people.

That is a full-frame fisheye (180-degree FOV diagonally) but the Sigma 8mm is fully circular (180-degree FOV in any direction), so both extremes are available without modifications. So that's left is the $150, it could be. –  Itai Apr 25 '12 at 3:40

You save a lot more than $150 if you already own the 10.5mm! –  drewbenn Apr 25 '12 at 4:40

@Itai - I would never underestimate the brand devotion of any particular segment of society, and that includes photographers. I'm sure there are people out there who would rather shave a Nikkor than "defile" their kit bag with a Sigma lens. ;-) –  Andrew Heath Apr 25 '12 at 9:41

The original link is actually my article and lens.

I shaved the petals off the lens because I didn't want them to show up in the full frame camera images. Although I already have the 16mm fisheye, the 10mm shaved is a totally different look and although you don't get a full circle, it's better than spending more money for a new lens.

I wasn't concerned about warranty as I'd already had the lens past the warranty point and since moving to full frame cameras, would have sold this lens anyway.

@Dan Harper - citation needed. You cannot quote yourself. We need a reliable source! (totally, 100% kidding!) :-) –  Andrew Heath May 2 '12 at 1:23
