Ah ok so it is the sigma 15mm fisheye which I do not consider as I have a canon 8-15mm

Precisely. Specifically the Sigma 15 mm for Nikon. The same for Canon - which I assume exists - probably has built-in motor.

If I really want fisheye with AF there's the Nikon 8-15 mm for F-mount, which is said to be excellent and works just fine on the FTZ adapter. But it's expensive, so I'm holding off.

Yep, the Nikon 8-15 is excellent but, as you rightly say, kinda pricey. I've been using it on my D500 and D6 topside

Yes. It's possible the Tokina 10-17 works with AF on FTZ, I haven't looked into that. My plan for fisheye is to wait until there's a native Z fisheye. Fisheye should be a type of lens for which the Z mount has significant advantages over F mount.

No Z fisheye is yet announced so if fisheye really takes my fancy I might have to reconsider somehow.

I've just tried it. That won't focus either with the FTZ.

Oh well. Not unexpected. But thanks! Then I won't have to think about that.

Sadly no. Utter bummer on the Sigma 15mm.

I didn't realise the Sigma wouldn't auto focus with the Z-system FTZ adaptor. But then lack of AF is hardly a problem with the Sigma 15mm.  Set it just before infinity at , say, f11 and you're good to go!

that doesn't seem right - behind a dome it has to focus on the virtual image, which is 3 dome radii out at infinity.

Presumably it would be relatively easy for sigma to release a Z capable fisheye, they already make AF motor equipped lens for other camera models.

Yeah, but on the other hand, I was aware of it when I bought the UW housing, and I got it for a good price. Buying for the D850 I also owned by then would have been less optimal in many other ways, for my particular circumstances.

About focusing - precisely. I guess I could pre-focus at slightly closer than 3 x dome radius and see what that gets me, and then just continue experimenting. I won't know until I have a chance to try, which is still maybe 5 months away.

Sigma definitely knows how to put AF motors in their lenses, yes. So they could do it for F-mount. So far they haven't made any lenses for Z specifically, but some noises in that direction have been made. I'm open to third party lenses so I'll happily look into all candidates!

You get more lenses for a Panasonic full frame than nikon or canon
 

Well, both yes and no. Only looking at native lenses, yes. For me, being able to use - almost - all of my Nikon F glass on my Nikon Z cameras is a huge plus. And counting them, which is not unreasonable since there isn't really any penalty for using them, the choice for Z is a lot better.

Nikon adapters for third parties dont support AF
Nikon is very captive once you are in you stay in

Again, depends what you mean. The FTZ adapter does support AF for third party lenses, such as Sigma and Tamron for F-mount. I did have some trouble with version 1 of the Tamron 15-30/2.8, but that's rather an exception.

It's true though that Nikon is secretive about its mount protocols and everything has to be reverse engineered. I think that's a bad decision by Nikon.
