A wide rectilinear with AF that works behind a 140mm is definitely very appealing. How stopped down does it need to be for useable corners?

I must have found a different Viltrox 14mm online, the one I saw was manual.

Welcome, also from BC!

If you're using Nauticam and considering compact manual rectilinear options I'd look at the adapted Nikonos.

The 8-15 AF FE is obviously a huge question, especially if it looks like it could take a TC.

I ran the 12-50 in that port with the WWL-1, it had to run at 14mm because of the WWL-1 but not because of the port. Also compatible with more diopter mounts. But you give up the rather dubious "macro" setting.

If you run the port for the 60mm macro then the WWL-C won't vignette at 12mm.

Keep in mind the WWL is a bit of a fisheye. Have you considered defishing in post? Or do you want something tighter than the 8mm in addition to being rectilinear? There have been people who like the 8-25 but that's a pretty expensive lens which needs expensive ports.

I don't know of any domes which are coated on the outside, it would be attacked far too easily.

Have you tried de-fishing in post?

To my mind this would be ideal for Giant Pacific Octopus, letting me get a wide perspective inside the den while also being a decent FL for filming if I happen on one out for a stroll. I'd prefer to have it on a flip holder. If it folded over the port I could see 3D printing some sort of cradle to support it when folded and possible add flotation. I'm not a huge fan of the stix since they lose flotation past 30m but I rarely do macro that deep anyway.

hopefully they offer a float collar as well.

Price quoted at $999, so more than the MV60 which makes sense given how much more glass is in there. I'll be very curious to see test shots and specs.

Which version of DP100? There are ones for the Tokina and the Canon with different extension built in. I believe you can use the Tokina version with a Canon if you add a 20mm extension.

The ports and lenses, depending on what they are, might be worthwhile.

On Sony you need the 35.5mm N120 adapter plus the DP100T for N120. I wouldn't buy the DP100 new, I'd look for a 140mm port instead. But the DP100 show up used fairly often.

That Sigma 20-200 is very tempting as a do-everything sort of lens. Like the 12-50 on MFT but both wider and tighter. Should be a very easy zoom gear to make as well for us Nauticam folks.

You are thinking of the EMWL. I'm talking about this lens: https://www.nauticam.com/products/macro-to-wide-angle-lens-1-mwl-1-150-deg-fov-with-full-frame-60mm-macro-lens Although obviously nowhere near as wide.

Like an MWL-1 for longer focal length and not quite as wide. I'll be curious to see cost and some test shots.

Bit of a bump, but anyone fancy a 160mm hemispherical dome: https://rovmaker.org/product/underwater-optical-glass-dome-lens/

Since (from what I understand) the projection on this is skewed closer to a rectilinear do you think it would benefit from a larger dome? Added to that does anyone think it would de-fish with less correction than say the 8-15mm lenses while retaining corner sharpness? Reviews above water are impressive.

Welcome from just across the water on Vancouver Island.

Try it both ways, mine is very clear when it lines up correctly and it's not 100% on the mark. Also a cloth soaked in hot water should help if you don't have a lot of water available.

The size is nice, I'm sure the AF will be very good as a native lens, lack of a compatible TC is less nice. Would need to be significantly sharper than the upcoming Laowa AF 8-15 to draw me to what will be basically a 14mm prime in my use.
