The shaving conversion is not difficult, just make sure to use an aluminum soda can/sheets from a aluminum can to protect the optics, tape against dust intrusion, measure accurately and go slowly.

While I found a trick to force FX mode on the Z8 and set the aperture on the 10.5mm as posted here: https://nikongear.net/revival/index.php?topic=11224.msg209380#msg209380, I finally broke down and bought a cheap dumb adapter to dedicate to the 10.5mm. I liked the design better than the one in that link, price was $25 lower, but might need to add front/rear caps that do not come with it.  The F-mount fit is nice and tight, while the Z-mount side is looser than the FTZ II adapters I have, more the same resistance as mounting the 24-120mm. An Amazon review stated that it has a plastic Z-mount, but I am pretty sure mine is made of coated metal. The register distance seems OK. I was able to calibrate the aperture clicks to a mid range setting of about f/ 5.6-8. The ring has a dampened feeling to it, probably due to generous application of grease to provide the illusion of a precise mechanism.

Thanks Erik, much appreciated, especially coming from you. The first thing that came to my mind when I was searching for that soda can was the classical thread with Jacov and all the the soda cans, wondering if one of the cans in that collection would fit the 10.5 mm.  https://nikongear.net/revival/index.php?topic=66.msg252#msg252. Again thanks for putting me on the path to this conversion.

He he, I often think of that image with the Can shower 
Thank you!

Nice work all.  Thanks to this thread, I've been inspired to find a 10.5mm lens.  I managed to snag a used 10.5mm for a nice price.  It will arrive soon and will be under the Christmas tree for me to open later and be surprised or at least very thankful.

Since this is for use with a Nikon D610 and I already have a Nikon 16mm f/2.8 fisheye, the 10.5mm will be going under the knife to remove the petals for full frame use.
