The direct ancestor of AX700 , the Ax100 had parfocal lenses. https://photographypx.com/best-professional-video-cameras/
External mounted mics like Deity has very bad quality, if you try to record a couple of people sitting in a room, because they are often too directional. To record a party of a conversation where there are a lot of people around you, the internal mics of camcorders provide better quality audio.

You claim all these camcorders have true parfocal lenses? Which ones? Want to list them, with references?
That article lists the 100 yes, but that is not your camera.
And their info may be flawed - I see no actual specs from Sony that states it is capable of that, nor that yours is. I suspect the reviewer of the article just felt it was within the margin of focus to be considered as such.
You really are out of your depth WRT sound. If you are trying to record people sitting in a room, probably one of the WORST choices for audio is to use a camera mounted mic, whether it is a 3rd party add-on (Deity) or a built-in one.
ALL of the respected pro/semipro audio sites and most of the videographer ones recommend directional shotguns over built-ins. Not least of which has to do with isolation from camera, and cam operator, noise. As well as better transducer quality.
Look at it this way in terms of your referenced example production:
Whether you are recording from an onlooker perspective or an insider/participant perspective, you DO want directionality to "focus" the intended voice as the dominant one at that moment, but you also need nearness for clarity and reduction of confounding room ambience - AND you want stability of perspective. The best choice is a directed overhead shotgun boom mic (mono), or a ceiling directional mic array, or a tabletop boundary mic(s), or set of lavaliers (mixed together), or even old-school sets of mics on stands (table or floor).
Or if you want to stage it as a "found environment" with natural multichannel ambience and less speaker dominance changes, you would use a floorstand/ceiling-mounted stereo/multichannel/binaural/ambi mic set that NEVER moves, and the mind would gloss over the A/V perspective disconnect.
But if ONLY on-cam mics were available, a directional mono mic would more closely match any change in camera "perspective" exhibited by repositioning or panning, while not also affecting viewer playback environment. Look to the left, person A is being focused on and their sound gets louder in relation, look back to the right and person B gets louder. And it matches the camera's movements, yet is still the same stable environment to the end listener, who may be listening with speakers or headphones. A stereo or multichannel built-in setup that follows panning would exhibit a form of "shifting room" effect, as the ambience/environment would be shifting perspective along with the direct sound source, and that is more distracting/confusing to the viewer. NOT professional.
I suspect you keep thinking like a video person and not an audio person, forgetting the the 2 should not be approached the same way and the choices made for optimum quality diverge greatly with respect to positioning and perspective.
So, I'm curious, what does this or any of the last 20-odd posts have to do with lossless NVENC HEVC capture with camlink?
You have been going off on different tangents to boost your cam's cred, but it's really unnecessary. As I stated, your cam is pretty decent as a prosumer cam. Would I recommend it for moviemaking? Probably not, unless "guerilla" or "indie" style. Would I recommend it for its audio? NOPE, in that respect it is just average for its class.
But if you have been given suggestions on ways to avoid quality issues in capture, there's no need to deflect as a defense mechanism. Just take the suggestions and try them out, using scientific methods as your guide.
ALL Prosumer camcorders have parafocal objectives
Moreover AX700 have built in ND filters too.
About audio. Deity is a good mic for the external outdoor street recording category, but it is not even close to the sound quality of built-in mics of pro-sumer camecorders during indoor (room) recordings.
Deity produces only dual mono sound instead of real stereo (My two AX700s have real stereo, my FDR Ax53 has dolby 5.1 mic set.
And honestly, what's the big deal with parfocal? Dynamic focus is amazing these days. And the breathing is generally far less worse than the style of "shake the hell out of the camera" (a style I've hated for the past 2 decades now). In fact, there's something to be said for a zoom and slow deblur, style.
As I stated, your cam is pretty decent as a prosumer cam.
Deity is worse than the built in mix set in indoor conditions.
And I will repeat the simple hard-fact (learn economic history, it is an interesting subject )
That's why USA was ousted from global industrial export markets of the first world countries by Germany both in quantity and quality terms since the late 1980s . Especially in audio-visual electronics, the American products were superseded by Japan products since the 1970s.
Haven't you heard about the mathematically lossless HEVC encoder of NVIDIA cards? It's an old story. LEARN: https://www.wikiwand.com/en/Nvidia_NVENC
You can simply record the uncompressed HDMI signal of the camera with the help of the Nvidia card.
Why is it so complicated to understand for you?

Deity worse than built-in? Right.
USA wasn"t "ousted" from anything. No, it was desire to cut costs that moved manufacturing to Asia. Yes, that started in the 70s, you got something right at least. But since the 90s, Japan and Europe now outsource as well. Japan to rest of Asia, Western Europe to Asia and Eastern Europe. You act as if this isn't common knowledge. It's why Walmart is full of cheap Chinese shit. Or eBay and Amazon, etc. Great example = those horrid Easycap cards, garbage. Some UK person had the "bright idea" to make/dropship it from China, and then it got further KO'd by Chinese stealing plans (typical) and making it cheaper/worse (typical). Some/most/all of your precious Sony camcorder is made in non-Japan Asia. We live in a global economy, and have for decades.
The fact is you're calling a highly compressed format "lossless", which is fine in the right context. But to act as if it means "uncompressed" is false.

So what you you are saying is:
You need confimation that your capture method is of the highest quality.
But when confronted with holes in your methods, you go down an increasingly divergent and bizarre series of rabit holes of topics and hyperbolic proclaimations and braggadocio, even when repeatedly faced with facts counter to those claims.
Culminating in national and personal insulting and taunting.
Yep, classic TROLL.
No need to engage further.
