Hello everyone,
just wanted to mention that these 'old' Nikon fisheye lenses:
6mm f/5.6 220°
7.5mm f/5.6
8mm f/8
10mm f/5.6 OP
work perfectly on a FTZ adapter connected to a Nikon Z mirrorless camera.
Watch this demonstration:
https://www.youtube.com/watch?v=obRsVXkUl2g
Here on this site I found the info that it is possible to use these lenses on a D800/D810.
It's not as straight forward as connecting them on a FTZ adapter, but they work perfectly well on my D800E.
So the information of Nikon that these lenses are incompatible is just plain wrong.
-
I have used the non-retrofocus Fisheye Nikkors on DSLRs for more than a decade ....
Nikon has a very conservative approach thus will not recommend this practice as there is a risk of damaging the camera mirror. However, provided one is careful the use is unproblematic.

Does that small 6/5.6 really cost £30.000?
I thought it was the huge 6/2.8 that was in that price league. But the small one is much more portable so probably the one most people want to use in the field.
The 6 and 7.5 may be an interesting lens for the Z50.....and then use software to make it an ultra-wide angle lens?
-
That would be a very expensive and awkward approach to getting a ultra-wide for the Z50 :)
The AF 10.5mm f/2.8 Fisheye will function on the Z50 via the FTZ (though, only manual focusing). This Fish is very sharp and likely miles ahead of older designs in terms of image quality. The AFS 8-15mm f/3.5-4.5 Fisheye zoom lens should not be overlooked either. Can do service on either DX or FX format cameras.
-
When I had D2H, and Nikon Capture then employed de-fisheye function, I tried AF Fisheye 10.5/2.8. The de-fished image was just marred by tons of CA and smearing peripherals (not just the corners).
Of course, the 4MP is not up to any stretching, but, considering the amount of necessary correction for the de-fishing, A fisheye lens would not be a feasible alternative to a super-wideangle.

I have used the 7.5mm f/5.6 on an FTZ on a Z6 and was very pleased with the results.

Yes! The "Minus Seven" is a phantastic lens on any camera...

"Minus Seven"? …..is that the 6mm?
The 8-15 is probably the lens to look for. I already have a Nikkor 12-24 DX so a 10.5 does not give that much more in terms of wide-angle. But Nikon sell a refurbished version of the 10.5 in the moment.
A 8-15 on a Z50 should give good results even at 8mm I assume.
Is NX-D able to de-fish the 8 - 15mm?

I wonder if people know that there Nikon made a few 220 degree 17.3mm f4 fisheye lenses for MF. Check this out :)

More than that, I have reported on it here on NG:

Wow, Stanley Kubrick would have loved to use it as the red eye of Hal 9000!
-
One of the reasons for me to buy a Nikon Z6 was to use my 10mm f/5,6 OP-Fisheye more comfortably. I bought a second FTZ-adapter dedicated for tha use so I need to take less care when changing lenses.
-
You could even put the 10 OP on a focusing helicoid ....

Good idea, currently I havent got any
Would love to have more closeup capability but K1 ring appears tobe too much already
-
Took me less than 10 minutes to cobble together the bits and pieces to make a focusing adapter for the 10 OP (and its sibling Fisheyes) on the Z system :)
Proof of concept. With the Z50 thus the image circle is clipped in this case. Handheld "wide open" at 1/13 sec and the front element is almost touching the book spines. The helicoid allows infinity focus apparently, but night time now so hard to verify. I might find a slightly shallower M42-Z adapter later to ensure a wider focusing range.
Components: K-3, 12-31mm helicoid M42, home-made M42-Z adapter (flat).
Interestingly, even at f/5.6 the 10mm focal length does not allow an extensive depth of field if one brings the lens close enough to the subject.
-
In broad daylight, I was better in a position to assess the focusing capabilities of my makeshift dapter. Turns out it does allow the 10 OP to go all the way from (beyond) infinity to as close as one physically can bring the lens, meaning literally to the surface of the front element.
-
Thanks Birna for your input:
I also had the impression that the DOF is not as large as I expected it to be at f/5,6. For close-ups the lens needed to be stopped down exacerbated by the fact that the reach towards the closer end is not as good as I'd like to have it.
Havent thought of equipping the lens with a focussing unit instead of the adapter
OK now I could make use of my K3 ring, If i manage to get a suitable focussing helicoid and a M42/Z adapter that is flat enough
In case of success the second FTZ adapter will remain usable anyway
-
The exact parts used for the focusing helicoid intended for old Fisheye Nikkors:
1. A standard K-3 ring
2. A 12-31mm M42 helicoid (eBay, many similar, but select the narrow range as the helicoid needs to compress to a maximum to give infinity focus)
3. M42-52 step-up ring (a flat version, preferably)
4. A Petri M42 adapter + stock factory Z bayonet + epoxy glue to make a flat M42-Z adapter. Probably something similar should be commercially available.
I already had made several of the part (4) so spent most time rummaging through my bins to find parts (1)-(3) :)

Thanks for the additional advice. The crucial issue probably is to get the adapters (#3 and #4) flat enough
-
The M42-52 step-up ring should be pretty flat in most versions.
For the M42-Z, I can if need be make more of these provided I have available parts.
Edit: the Petri M42 adapter probably can be made superfluous or replaced by any flat M42 adapter that will fit into a stock Z bayonet. I can easily order more of these bayonets from Nikon, if there is any interest in such a project.

An adapter overview ....
(https://nikongear.net/revival/index.php?action=dlattach;topic=9527.0;attach=45238;image)
This admittedly crude and ad-hoc solution works with all my old fix-focus Fisheye-Nikkors, providing them with a truly extended focusing range from infinity down to the surface of the front element. Just have to learn to be careful to avoid bumping the lens into something when it is close to the subject. That in particular is necessary for the 10 OP as its front element is quite soft and easily marks.
-
Thanks Birna for the picture and for the offer to make more adapters.
At first I need to get a proper 12-31 mm helicoid.
I also experienced that the 10mm Fisheye needs extreme care when trying to get close- for not getting contact, better start at close distance and move away
Did not know that the front element is that soft- so far I managed to avoid complications.

I will never sell my Nikon 10,5 - I was stupid to do it (wanted new camera-stuff) but bought it quickly again ;) - Therefore I also keep the Nikon 7100.
I use hemi-software to convert sometimes when needed.
