Exactly… no real calculations to show….

Not trolling….. enlighten me with where you think the lens fits in the A139 remote camera. I want to see that 5-8 years experience come to play, without physically buying the camera or lens… lets see that design.Still trolling obviously.
Hope your new lens fits after all of your "calculations"!

Would love to see what you come up with.
It’s simple… its eitherSo, you claim not be a troll but here you are still baiting me? No thanks, I have no interest in having any further interaction with you. "Don't feed the trolls", as they say.
I don't think any third party lens will be a simple plug and play with this remote camera. Not everyone has the right tools and parts to open the housing, remove the lens, focus the new one and secure it in position, and finally figure out how to mount it. It's not hard, but it takes a good hour or two to get everything done and back up and running in the car, not accounting for further focus or position adjustments.Should another person browsing through this forum purchase the same 8mm lens Tony purchased (to be installed on the A139 interior/exterior camera)? I would advise against it, especially if they are new to this since its not a simple plug and play.

Yes, of course there are differences. But are they enough to justify buying another camera, having another camera on the windshield, using more power in parking mode (2CH vs 1CH)? I like having the redundancy of a second camera, and looking at other examples there are times when the difference between these two is much greater, so I will continue using 2 cameras. However I am already thinking about installing this 8mm telephoto in a higher resolution camera.
We just got a new idea about how to implement this, it will come with better specs, and it will take some months for development.I don't think any third party lens will be a simple plug and play with this remote camera.

I fully agree with that. You don't want regular customers opening up cameras.We do wish there is no necessary for the user to replace the lens and do the focus.
that’s the one I ordered. There is a missing dimension on the drawing which could impact how it fits through the camera cover. But I assume that’s 14mm…or hope it is (just looking at how big it is scaled between the 12mm and 18mm diameters). The seller hasn’t given me that dimension yet.I have been looking at this 7.8mm lens, as an alternative to my 8mm lens. I recall it was mentioned here a few days ago.
I don't think it was an option when I was looking at lenses in November last year. There was a 6.8mm lens, but not 7.8mm.

I took a few more measurements of the lens holder in the A139 remote camera and measured the thickness of a typical sensor. Assuming the lens diagram and listed dimensions on AliExpress are accurate, I estimate that this lens will have approximately 0.5mm thread engagement within the lens holder. At 0.5mm pitch that might give a full turn so it might achieve focus, but it might not be a solid connection. So it would probably end up needing a longer lens holder, similar to what I used for my 8mm lens.
I would agree. Have had no luck finding anything in between 8mm and 12mm though.Been rewatching some of my old videos from the 8 and 12mm, and samples in this and other threads by TonyM. I feel 8mm is not enough zoom and 12mm is a tad too much. Haven't come across any 10mm lenses on AE in my past searches, but if Viofo is looking at a custom lens, 9.5-10mm IMO would be the sweet spot.
I measured the aperture at 14.1mm (min) if you really want to know. That won't be a big problem for the 12mm lens though, since the front plate is ~17.5mm from the sensor. The front end of the lens will sit just in front of the plastic front plate.Also looking at the 12mm version but the 15mm diameter might be too big to fit on the lens cover; preventing the lens to go in or I won’t be able to put the cover back on. I don’t have dimensions for that inner diameter.
Did you happen to measure the diameter of the lens cover ID? I recall you said the 8mm lens you had just barely fit and that has 14mm diameter within that section. I think the hole in the cover might be 14.5-15mm since it had a bit of clearance. But that clearance really is meant for positioning tolerance. So the 12mm I’m looking at would have issues fitting through.

You would have to slide the lens in through the hole before screwing it into the holder. I did that with my 8mm lens. The tricky bit is getting inside to tighten the lens collar once you get the lens in focus. You can see that part-assembled state in this photo:
