Nice job. There was an interesting thread on this topic that was started by Steve Williams a few years ago. It is here:


In Topic: DX to FX and back again

Hey Tom


Yeah, I saw that this morning. Sounds a pretty funky lens! But just how useful is a 180 x 180 circular fisheye - after the first dozen Wow photos?


I have two copies of the Canon version. I have used both at the same time with each housing set up with a different diameter port to accommodate different water depths. This lens is my most used lens. The Nikon 10.5mm is my most used Nikon lens.


The the 8mm end is specialized. The lens shade must come off the port which exposes it to potential damage so I have used the 8mm setting sparingly and taken extra precaution to reduce the chance of having the port crash into the bottom when used in streams. I have just one resulting "winner" shot.


I got around to using it on an APSC sensor this year (topside shots). I am currently using one on an APSH sensor camera with a 100mm diameter port to use in very shallow water, e.g., 8 cm. However the characteristics more important IMHO are weatherproofing and close-focus ability. These characteristics also apply to this new Nikon lens. The old 16mm D lens was lacking in this department. The only downside for both brands is a smaller maximum aperture compared to the old primes.For underwater use this mainly affects focusing at low light levels. New cameras, however, are improved in their ability to focus in low light negating this issue.

Justification for sticking with FX may be announced shortly:


Especially if this is anything like the Canon 8-15 qualitywise.


No longer a rumor:


Note the minimum focusing distance!!!!!

I saw the prototype at ADEX and reported on it on the front page.  They looked very nice!

Good to hear. The strobe model 60 development was mentioned back at DEMA 2015! See: http://wetpixel.com/...om-dema-2015/P3
