High native ISO and UV/IR sensitivity mirrorless camera? Graphene CMOS or QIS sensors any time soon?

Hello. I’m looking to convert to full spectrum new full frame or crop sensor mirrorless camera with ~20Mp resolution.
My main requirement mirrorless camera is high native ISO and enhanced sensitivity in UV/VIS/IR spectrum (or even reaching SWIR) after full spectrum conversion but features in newer models like IBIS, phase focusing, high native ISO. 4K recording, better viewfinder, high refresh rate, pixel shift (or other way to boost static object resolution) is also desirable.
I liked previously owned Sony A7s camera which had incredible sensitivity and 409600 native ISO which after FS conversion basically turned into night vision device, videos would look great. Unfortunatelly A7s doesn’t have pixel shift technology to increase resolution of static object which I need for art work documentation/analysis while already ridiculous resolution camera’s utilize this technology, what a shame. I will also need a high quality lens that is fast and sharp both in IR and visible. So that’s why I’m now leaning toward choosing different brand camera such as Canon and Nikon F mount seems to have bigger selection of lens than Sony in terms low infrared hotspot.
Do Z mount camera to F mount lens adapters work well?

Is there new sensor technology being used in mirrorless camera’s? Camera sensors unfortunately did not change really much. Major shift was use of backlit CMOS sensors which are better f-stop in noise reduction and I read they are also more sensitive especially to UV but later camera sensor are also using coatings which may block UV/IR. Sure there are small improvements like dual gain pixels, stacked or global shutter sensors but these novelties have no effect on spectral sensitivity?

Nikon is developing QIS sensor technology. Quantum dot three layer sensor are also in development. Even more amazing is graphene-enhanced CMOS claimed to have x1000 more sensitivity. High sensitivity is really needed to reduce pixel and camera/lens size/weight. Metalens are also very interesting as alternative to bulky, heavy and expensive lens.
Are there any cameras that use different color filter mosaics with better IR/UV transmission such as RGBW? It would be great to have pixels more sensitive to UV and IR to get more interesting artistic color effects.

I can't help you with some of the more esoteric questions you pose, I can, however, answer at least one.

Yes, the FTZ adapter works well. I use one to adapt my 200-500 F5.6 F mount zoom to my Z5 and Z7ii cameras. Everything works as advertised. I will say that looking at comparable lenses, the Z mount lenses are typically superior, and it's nice not to have to mess with an adapter.

Why are you even considering a meager 20MP sensor for this job if pixel-shifting is something you require for higher resolution? 45MP or larger sensors are there to have and don't depend on pixel-shifting at all. If it is a cost issue, you are naming off some very expensive technology and could not afford any of it today anyhow.

As for the Nikon Z-mount cameras, only the crop-sensor APS-C bodies have 20MP sensors, and they do not have IBIS or pixel-shift. The full-frame Z-mount cameras go 24MP on up. And then I have to ask why the interest in using F-mount lenses when the Z-mount versions pretty much are better anyhow?

Really from my point of view, you are overthinking this. I do not know what your photo subject is supposed to be, but full-spectrum conversions are almost always for taking astrophotography subjects. Infrared conversions are typically landscapes in daylight. If you are intending to do astrophotography, the method is to take hundreds of individual photos and combine them at a computer. This is exactly what pixel-shifting does in camera in a smaller-scale. So the pixel-shift is redundant and limiting.

Please clarify for me if I'm off-base.

I want to keep resolution as low as possible for better low light performance since as I understand currently only biggers pixels are more sensitive. Pixel shift is great for static imagery and I want to do artwork documentation in visible and infared spectrums but I heard pixel shift can be easily ruined by slightest vibration even from footsteps in other rooms. F lenses are are cheaper and there are more options for infared hotspot free lens. Z lens are new and not yet so well documented. Are Z lens reasonably more sharper than F lens, any new technology?

My understanding is that the new Z mount with a larger opening gives the designers more options for optical designs. That, and they are the latest designs. Nikon, and most other companies have stopped designing DSLR mount lenses and cameras. They are still manufacturing them, but only current models, no new ones forthcoming.
