This becomes very apparent in some tests, when they zoom in to 20x or 30x on objects that contain letters and words: while the rest of the image looks surprisingly crisp, the AI generstes fake letters that are sharp but completely unintelligeable.

The only thing affecting the light on a sensor is aperture and shutter speed. Of course it matters the quality of lens and photodiode that catches the light. Bigger sensor means only a shallow depth of field and, sometimes, bigger photodiodes

Apparently, oppo applies heavy noise reduction, smoothing the details im RAWs.
Should be more visible at 12000 ISO.
If you got any experience, feed back.

For example, true optical zoom never reduces the megapixel count. But that's a different topic.
The S23 Ultra only offers 45% as many pixels per angle as the Oppo X9 Ultra. That's actually a big disadvantage for the S23 Ultra. So theoretically in this regard, the X9 Ultra can digitally zoom 2.2 times as much as the S23 Ultra.
But the X9 Ultra apparently has a Quad Bayer color filter array, which is often worse than Bayer regarding the level of detail.
Furthermore, the Samsung JNL sensor possibly uses Quad Pixel autofocus (like the Samsung JN5): Then the low number of microlenses (only 12 million) can reduce the level of detail.
The S23 Ultra also has a significantly lower effective lens diameter: 5.55mm vs 9.94mm
This means that the X9 Ultra can capture more light from objects per exposure time and it also means that the maximum theoretical resolution of the lens regarding distant objects due to diffraction is much better. Theoretically, regarding diffraction, the X9 Ultra can digitally zoom 1.8 times as much as the S23 Ultra.
But of course the image processing is extremely important for the jpgs. The S23 Ultra used a lot of aggressive AI at 30x, this made the S23 Ultra's photos look better (for some people) than they really were because the S23 Ultra produced a lot of fake detail at 30x.
On the other hand, the X9 Ultra produces fake detail as well...

The effective lens diameter of the periscope camera is 9.94mm. This means that the periscope camera gathers as much light from a distant object (for example Jupiter) per exposure time as a 230mm f/23 lens (no matter which sensor size).
I just want to stress that the amount of light from a distant object (or object in the center of the frame) per exposure time does not depend on the sensor size. It solely depends on the effective lens diameter (entrance pupil diameter).

I also don't like to discuss with someone who doesn't have any arguments because he/she just writes "You are impossible and wrong, I don't really wish to discuss." and spreads wrong information, whereas I explained everything politely with a detailed answer... That's just a waste of time for me.
What I say is nothing new, so yes, there is nothing to discuss indeed. That's the reason why telescopes are so large. A large telescope does NOT need a large sensor, many planetary astrophotography use small sensors as I already said. As I said, a sensor can not magically increase the number of photons from an object after the photons went through the lens... The only additional amount of light per exposure time a larger sensor can capture (in comparison to a smaller sensor) comes from objects within the additional field of view, if the lens is the same. I don't know why I have to repeat it. I already explained it in my previous post. A sensor only measures(!) light. Newer sensors can measure light slightly more accurately than much older sensors, but this doesn't depend on the sensor size.
"You must adjust the sensor position (and hence, focal length) "
Wrong, I even don't know what you are talking about. A sensor doesn't need to move at all. The distance between sensor and lens (or lens elements) is what changes, when a camera focuses, the sensor doesn't need to move and the focal length of a prime lens doesn't change. Focal length is a property of the lens.
A larger sensor only captures more light per time from an object in the center of the frame, if the image is not focused at all. Actually, there are concepts for cameras/sensors that don't really have a lens (so the image is not focused and algorithms have to reconstruct a focused image), but no camera on the market works this way.

Why these 10X photos don't look much better than those from S23U (especially with gcam mod)? Is this an early software? Sensor wise it should be miles better or is it because of the blurry optics?

You must adjust the sensor position (and hence, focal length) to properly project the scene onto it. You are too oversimplifying optics, as if it was that simple. It is not.

The overall RAM and chip crisis is mostly responsible for the steep increase in price.
That being said, luckily there is not much difference in overall image quality between the current crop of Ultra phones and their predecessors from 1-2 years ago.
So, whoever got a Xiaomi 14 or 15 ultra, or a Samsung Galaxy S 22 or 23, will photographically basically be in the same ballpark as with the Find X9 ultra or the Xiaomi 17 Ultra or the Samsung 26 ultra.
Yes, there are certainly marginal differences, but they definitely do not justify spending 1700-2000 bucks for the latest iteration of the same stuff.
There are still laws of ohysics at work, and a 1/2.7" type sensor (as in the 10x zoom lens of the Find X9ultra) can only gather that much light. Same rules apply to the near 1"type sensors - compared with APSC or FF cameras, they are still tiny. Thats why low light videos of all these ultra phones still look extremely bad: In video, the device cannot apply nearly as much comoutational imaging and image stwlacking as in stills photos, so videos look outright unusable.
That being said, the Oppo Find X9 is probably the best cameraphone compared with the competition.

No. It's not about light per unit area. Light per unit area (of the sensor) per exposure time depends on the f-number, not on the effective lens diameter.
When it comes to the total amount of light per exposure time from an object in the center of the frame, then the sensor size doesn't matter, it only depends on the effective lens diameter. That's obvious because a sensor can only measure the light that goes through the lens. Many planetary astrophotographers use very small sensors (for example 1/3" type) because it does NOT affect the amount of light that is captured from a lunar craters or from a planet, etc. A sensor doesn't gather light, it only measures light.
The only additional light a larger sensor measures (in comparison to a smaller sensor) is the light of the additional field of view (if the image circle is large enough), if the lens is the same.

Hans, 25 Apr 2026They charge what they think the market will tolerate, not how much it costs to produce. In my ... moreThat's partly because overall component cost has increased significantly (thanks AI bros!)
TSMC (the current global monopoly in leading edge node tech for smartphone chipset) has been raising their price every year (this year alone is about 10% - imagine how much the price inflate after 10 years!) which then forced Qualcomm and Mediatek (and other chipset maker) to raise their prices and their own margin too.
The trio DRAM mafia (Samsung, Hynix, Micron) are also partially responsible. They increase the price so much (and let the AI bros hoard the commodity) that many small companies will eventually collapse because they can't get the part needed for their product. Heck, even Samsung's smartphone division is worried that they're losing money this year despite the fact that their sibling (Samsung memory division) has achieved record profit. USA banning chinese memory maker from acquiring ASML machines only makes things worse for the consumers as there will be no one to stop the mafia from fixing the dram price...

e.g. bigger sensor will capture more photons than the smaller one, so your math will break there.
And that is assuming we have a universal "lens system" that can serve both sensors the same.
You must look at it as a total combo lens+sensor system to properly analyze it.
