The shade will likely conflict with inside a mini (100mm) dome, but should have zero issues with 140mm fisheye dome port. On a APS-C camera, your diagonal view with drop from 185 degrees down to around 120 degrees. So yes, your FOV will be smaller..

I don't know about that Dave. I my case, it's more like the rhetorical question of which came first, the chicken or the egg? But I will affirm the current setup on my rebreather is a lot cheeper than the overall cost of my current camera rig.😉

Doing a search on what happened to 7Artisans new 10mm f/2.8 autofocus Fisheye Lens? The answer I got was that 7Artisans 10mm f/2.8 lens was not fisheye as it was first promised. Instead, it is an ultra-wide-angle rectilinear autofocus prime lens designed for APS-C mirrorless cameras (Sony E, Fujifilm X, and Nikon Z mounts) priced at around $199. Once again we have been snookered.

Cool! taking magic light tubes to a whole new level.

Dave, I know we have changed the subject, but it is nice to hear there are few KISS Rebreather fans out there. I have been diving KISS Rebreathers since 2005, starting with a KISS Sport and switching over to a KISS Classic in 2010, which I still use today.

Just took a look today (08/19/26) to see if there were any updates on 7Artisans new AF fisheye lens in Sony FE, Nikon Z and L-mount on both B&H and Adorama's websites to find neither had the lens even listed. Very strange.

Hi Igor, To answer question, the Canon EF 8-15 + Fringer II + Kenko 1.4 DGX should work in continuous autofocus and 3d tracking, same as the Sigma 15 with Canon EF mount that I have used on my Nikon Z8. I am pretty certain the Canon EF 15mm full frame fisheye will do the same as the autofocus motor is built in. Its Canon’s RF mount lenses for the mirrorless camera that cannot be used on Nikon Z bodies, as nobody has produced a RF to Z adapter. While the going price for a secondhand Nikon 8-15 is quite higher than the Canon EF version, remember that this lens requires Nikon’s F to Z lens adapter to work. As for the ports required, Nauticam’s port charts for Nikon DSLR camera can be applied the same way when using Nikon F mount lens via the F to Z adapter on Nikon Z mount cameras.

With the MFO-3, the field of view you see through your 100 or 105mm is altered to what you would see with a 50 to 60mm. In essence you have the best of both worlds for macro general macro work. Add a super macro diopter on a double flip holder, and there will be almost nothing you can't get.

Pentax did have a 15-28mm full frame fisheye before the appearance of the Tokina 10-17.

Here two things you can do to prevent this. 1. Don’t allow saltwater or freshwater where there is calcium present in the water to dry on the glass. If you can’t keep your housing in the rinse tank/bucket on the boat, wrap a wet towel around it. 2. After the dive(s) when it comes time to rinse/soak your gear in freshwater, be sure to dry off the glass with clean dry towel or cloth as soon as that done to prevent water spots from lingering. Even my face-mask gets this treatment I live in South Florida where our fresh water is loaded with calcium. If you allow them to dry in place they will leave micro deposits where they dry which are total bitch to remove afterward.
