Well its 48mp not 12... The size is a shame but leaves it open for the'S' model to have a 1 inch sensor again. However I know of very few one inch sensors above 20mp. One that a Xiaomi phone has is 50mp, that would be great. Ideally 30-40 would be the sweet spot.

Sorta true but also an outdated theory about sensors when it come to computational imaging.... at least for 'snapshots' - I also have a Z7, and II, and its miles better than my iPhone 14 Pro, there's no competition. Yet, the iPhone 14 pro is about as good as my Ricoh GR., certainly centrally. And much better than my RX100. Size isn't everything anymore

Yes they are. But 1" wasn't necessary to engineer a camera that improves upon the performance of the A2S with an older, technically inferior sensor.
As you point out, this made the dual camera design possible, which I'm very excited about.
The only stacked sensor I'm aware of is the FOVEON X3 as installed in the Sigma SD series DSLR'S. I think the reference concerned having one camera stacked on top of another.

Here's a good article explaining the design concept: What Is a Stacked Camera Sensor and How Does It Work?
The mini 3 Pro and Air 3 both have the same omnivision ov48c sensor. The air 3, as stated in their own literature has "48mp effective" resolution. They've pulled the same advertising stunt with the are 3.
In the context of photos and videos all the differences between the mini 3 Pro and Air 3 are in functions made available in firmware, not hardware.
I'd guess that part of the reasons why the features aren't available in the mini 3 Pro are to do with bottlenecks present in the main board components, due to partly to heat as a result of passive cooling.
Hence they were reluctant to add 10bit video initially.

The mini 3 Pro has a omnivision ov48c... Same as the air 3.... Read the specs and compare. Same sensors. Stacked.

The mini 3 pro does not use the same stacked sensor as the Air 3.number may be the same but it is already older technology
in the mini 3 pro.The new mini 4 pro when it comes out will probably have the latest stacked sensor technology.
My point is that they are very different technology. But hey, they're the same size right?
Eh??? If the sensors are the same, then how are they different???My point is that they are very different technology. But hey, they're the same size right?
Anyway... Electronics manufacturers don't tend to rest on their laurels so give it a year and I'll bet you'll it'll be dual 1" sensors for the air or something similar
Maybe 1" 20mp main and a 1/1.3 tele
The Mini 3 Pro, Air 3 and the new Osmo Action 4 all use the same Omnivision OV48C. Omnivision only makes one 1/1.3" 48MP sensor ( Product Archive ). The OV48C was released in January 2020 ( New OMNIVISION 48MP Image Sensor Provides Unparalleled High Dynamic Range and 4K Video Performance for Flagship Mobile Phones ), 2 years before the Mini 3 Pro.
Here's the datasheet: https://www.ovt.com/wp-content/uploads/2022/01/OV48C-PB-v1.1-WEB.pdf
In 2023, it's still a beast. Back Side Illuminated (BSI) for more efficient pixel cells; on chip dual conversion for improved dynamic range; pixel binning for better low light at 12MP/4k; and stacked die for improved pixel readout. It clearly outguns the Air 2s in most uses, particularly 4k/60 where the Air 2s crops from 5.3K, reducing the usable sensor size.
But better imaging in the Air 3? Main camera to main camera the Air 3 has an improved image processor so it can support 100FPS and better raw processing. I imagine operations like panorama processing are faster. Otherwise, they are identical as shown in this detailed comparison with a test charts:
The color science in video *is* different; the Mini 3 Pro seems to have dialed up the saturation to appeal to the general public rather than video-graphers. That can be readily corrected. Of course, there's a second camera on the Air 3 to have a narrower second FOV (tele zoom) and lots of other features.
Keep in mind, until about 2 weeks after the Air 3 actually shipped, all reviews were made by people who got free equipment from DJI and signed an agreement to get the free drone. Take what you read about "improvements" that are not on the DJI datasheet nor documented in any public way by DJI with a grain of salt.
Expect the Mini 4 Pro to have this same sensor; it is too soon to have the Mini product line outgun the Air product line. Expect the Air 3s to have m43 but only when DJI has taken all the money if can from people upgrading to the Air 3 and the Mavic 3.
To back to the OP's question: Am I concerned with the downgrade from 1" to 1/1.3"? No, the 1/1.3" is a significant step up in technology. But I made that decision when I bought the Mini 3 Pro.
M43? Got a link please? But yeah the tech inside that sensor is awesome.
I suspect dji could have gone balls out on the mini 3 Pro but decided to restrict a bunch of stuff to use it for the air 3... A lot of the features in the air 3 are software upgrades.
For me personally I bought the mini 3 Pro because it suited my use case better (A0) and I knew the sensors are the same so...
Like I said though, electronics companies don't tend to rest on their laurels, even if dji and the likes are happy to milk it for what it's worth, and I suspect we'll be seeing some new sensors soon. What omnivision did with the ov48c is top draw sizzle but Samsung and especially Sony won't take that lying down.
My got tells me that seeing the omnivision ov48c has been quite popular and had some decent demand, we'll soon see a 16 or 20mpx version of the ov48c. Maybe a 16mpx binned from a 64mpx bayer...
I'd love to see a 1" 24mpx version of the ov48c.. And with a decent GLASS Leica lens on it... I'd happily pony up the extra for that.
Yeah I figured the colour science had been tweeted when I used this image to prove a point... I'm not sure now if it's saturation... If you look at some side bu sides, especially of the sky, the blues are different and in the photo below the red is different... I think they've used different shades of RGB in the colour science.
It may also be down to processing maybe? I'd hope to believe that the air 3 uses better quality analog amp circuits and ADC chips and maybe that's creating some differences but then looking at the prices... Maybe not.

"air 3 uses better quality analog amp circuits and ADC chips"
Check out the linked datasheet showing the stacked die. The amp and ADC are inside the OV48c, so no change.
There's dual analog amp circuits after the sensor (as with all dual native ISO cameras)... That's how you turn the ISO up... You just add gain to an analog signal Then the ADC (analog to digital converter) turns it to 1s and 0s.
Which I'm sure you know. As you also probably know, not all amps and chips etc are created equally so I'd hope that a higher end drone would have higher end circuits and components but after watching that video, it doesn't seem to be the case... SNR doesn't seem to have been improved at all to my eye.
But yeah, I love the way that with the ov48c, instead of merging a frame from both the high and low gain amps to create a high dynamic range image, it does that on chip, freeing up cycles for other processes.
Given the form factor of the mini and passive cooling, I doubt it could accomplish HDR at 100mps. It'd most likely fry lol. I would imagine that EMI and crosstalk would be a utter ball ache to boot.
