Johan Borg: But what is a Color Filter Camera??

Its infrared. Output is dark sky and white leaves. I would call it nice if it would be at least 8MPx with some video recording, but this 5MPx sensor doesnt create nice images.

twinfighter: darker lens and smaller sensor? Crappy thinking. Look at the newest smartphone sensors. They are getting bigger and bigger

"yes, with any sensor from 0,1 inch to 1 inch or even more you are getting no depth of field." Front camera on galaxy phone with ultrawide lens and 1/4" sensor size has autofocus because THERE IS DoF...

"Look at the newest smartphone sensors. They are getting bigger and bigger" Then go on any review of S20 Ultra. EVERYONE is complaining about autofocus... Apart from that you completely missing the point of such action camera. Its about no depth of field. Everything is in focus and there's no need for autofocus which can go crazy if some particles will get on lens or focus on something near that isn't important.

" instead of the 2/3” sensor inside of the Osmo Pocket" Where did you got this info from? https://www.dji.com/osmo-pocket/info#specs It's 1/2.3”

2cvpickupboy: The Nikon P900 has been taking shots like this for years and the newer P1000 surpasses it with ease, the huge ball of fire sunsets I get plus amazing moon shots for a fraction of the cost and weight, small sensor, agreed ,but the glass is magnificent and with care I get images that surpass my D800 and AI-p 500mm f4! Regards Davy

Didn't anyone tell you, there is this thing called atmosphere/haze that means even FF and MF cameras will not improve IQ as greatly as you think? Just shoot with P1000 and then FF with proper lens. I was heavily surprised and now I know why people like these megazooms so much.

Jon Stern: Samsung already has a micro gimbal in the P20 Pro, I think it is. They had it on show at CES.

Samsung... in the P20 Pro? P20 Pro is Huawei smartphone from 2 years ago and there's no Samsung S20 Pro so what are you talking about? Also no smartphone before had this feature.

FrithjofA: Where do I store a 100MP (>50MB file)? How do I display an 100MP image on a phone display? What about the diffraction limit? Since the sensor is so small, and the lens as well, such 100 MP sensors are just marketing gimiks since the diffraction of a perfect lens would spread any sharp point over several pixels. Just take a 10MP image and upsample it to 100MP= same information content.

The marketing people tries to beet the laws of optics.... good luck.

ZC Lee: Honestly? With 48/64MPx it was making sense because of thing I wrote earlier (multiple exposures in the same time so you could get even 15EV dynamic range without any ghosting or it could just copy moving items from 1/200 pixels on 1/25 image) but 108MPx idoesnt make any sense. There's no reason to do it, because you dont need to stack more and you wont gain more details, because lenses in phones wont resolve more... Sony already acknowledged that - new flagship IMX700 will be the same size as this 108Mpx sensor so 1/1.33" but it will be just 52MP which means 1.12um pixel size. This will output 13 MPx images and I think that's sweetspot for smartphone.

BrexitDefCom3: I'm waiting for RAW samples. I find the other 108MP Samsung sensors results-all quad bayer, disappointingly soft compared to a 1020 Lumia, and fear that at the present level of technology, that unless they seriously increase the size of the pixels, that aside from topping a numbers game, they are wasting our time and our money. I suspect the Huawei 40MP =40MP wide etc Mate 30 Pro we cannot buy (no Google or warranty etc) is still about as big as you can go STILL after 7 years, from a sensor this size, and that there are limits- the jpegs from it are nothing to write home about, unfortunately.

"so they started increasing their resolution to 13MP (1MP more than the N8 Nokia) and 16 megapixels" Its opposite. For example Galaxy phones - S4 13mpx, S5 & S6 16mpx and S7 12mpx. Same with Xperia - 20, 21, 23Mpx and now 12MPx. Why? Because the phones couldn't handle it. You dont remember how phones overheated when recording in 4K? They went too fast into megapixels and they returned to smaller pixel count. Also people were crazy about thinner phones and camera bump was considered disgusting so we want back to 1/3" sensors. Now phones are way more efficient, people dont care that much about thickness (every flagship is thicker than predecessor) and also they have smart ideas to mitigate problems coming from such dense sensors. 1020 was very thick AF so they had a lot of space for optics... but It doesn't get anywhere near quality of current 64/108MPx cameras and I'm talking from personal experience.

10MPx sensor cant get different exposures in the same time. This 108Mpx sensor will output 12/27Mpx in default photo mode (depending on your setting). Because of that you don't need to worry about anything because running human will be taken from 1/200 pixels while rest of the shot can be from 1/25 pixels. It also enables HDR without any ghosting, even in video. In the end you can be sure that no matter who will take picture it will always be good. You will have low amount of noise in majority of shot while people in motion will be frozen and thats whats important for average consumer. If they will manage to get the same sensor with telephoto lens then good luck selling entry level DSLR with telezoom.

And these phones arent using JPEG, they are using HEIF compression which is way more efficient.

Jrgn: I think this one (Mi 10 pro) uses the same sensor. Except that Xiaomi doesn't make so much rumble about it, maybe to leave the honors to Samsung as a business partner. But look at those DXO scores...

https://www.dxomark.com/xiaomi-mi-10-pro-camera-review/

Mi 10 is using older S5KHMX sensors just like Mi Note 10 and Mi Mix Alpha. Samsung S20 Ultra has S5KHM1. Basically Xiaomi gave money for Samsung R&D to get exclusive sensor (S5KHMX) and later Samsung made their own version S5KHM1. This is not the same sensor because HMX has 12032 x 9024 and HM1 has 12000 x 9000. Based on what I know 100% HM1 has faster readout. I dont know about other things (I think its the same).

nerd2: It's 2020 and Samsung somehow crammed huge sensor (which is actually LARGER than 2/3" sensor old F707 used) into 8mm thick phone. And we have computational photography to make it even better.

Its not really 8mm thick, this camera bump is largest i even saw and its like 13mm including it. Cases for this phone will be extra thick if you would want to protect camera...

Max Iso: You guys mentioned 8k but on which of the cameras? The lower end models only have 12mp on 2 of their 3 cameras so they could only offer 8k on the 64mp tele camera which is fairly limiting IMO, vs the Ultra that could potentially have 3 modules high rez enough for 8k (WA, tele and front facing). Any info on exactly how many Ultra modules support 8k?

It is exactly as you think - 8K on lower model is from tele camera.

Fotoni: Phone cameras generally have improved specs for several years. Despite the bigger numbers, all I see is muddy details, washed out colors and highlight posterization. The only differences are bigger photo dimensions and the shape of muddiness. Very artificial look, but they look decent when resized to fit my screen...which is 2 MP. Not sure if there is real details even for 4K which is about 8 MP. My bet is that maybe about 6 MP is real photo data and the rest are noise which is manipulated with artificial details. Looks very muddy though.

https://fdn.gsmarena.com/imgroot/reviews/19/xiaomi-mi-note-10/hands-on/daylight/gsmarena_104.jpg and https://fdn.gsmarena.com/imgroot/reviews/19/xiaomi-mi-note-10/hands-on/daylight/gsmarena_103.jpg Is it really "muddy details, washed out colors"? For me its finally smartphone that gives nice detail without oversharpening.

kobakokh: There will be great photos, especially at high ISOs...

https://fdn.gsmarena.com/imgroot/reviews/19/xiaomi-mi-note-10/camera/gsmarena_018.jpg ISO 12800 1/4s f1.7. Seems fine to me, I can even see some stars and thats without night mode so theres no stacking... :)

Small pixels mean more noise per pixel but NOT more noise on image because noise is finer and if you have good noise reduction algorithms denser sensor = less noise. This is pretty huge sensor (for smartphone) combined with latest sensor technology with very small crosstalk between pixels and thats why you shouldnt worry how small are these pixels.

JEROME NOLAS: it will be prohibited in the the US because it can be ussed as spy tool...

All big US companies are full of great people, but nobody manages that good enough when company gets bigger. Even GoPro fits that. They come up with great product and fail to continue. Remember GoPro Karma release? Chinese DJI just destroyed it before release and look now - did DJI made better products since then? YES. So from who they are stealing now if they are leader? They arent stealing and they werent doing it just like Xiaomi doesnt do it. US companies are just crying that they dont get $$$$ and try to play on your patriotism but in reality its just about making money from you. Instead of having such mindset they could just move their fabs to US. iPhones are $1000... seriously they could make them entirely in US, but they wont do because they want more $$$$ so they exploit workers via Foxconn. They are just greed.

@Mike FL... Ok, so what exactly Xiaomi did stole from US? They have own fabs. CPUs, sensors, lenses etc. Apple is just using finished parts excluding OS and CPU (they are designing CPUs, but they are made by TSMC/Samsung). Xiaomi has huge R&D, I will give you example https://papers.nips.cc/paper/7484-deepexposure-learning-to-expose-photos-with-asynchronously-reinforced-adversarial-learning.pdf so yea... they know what they are doing. Chinese companies had "Night mode" 2 years before US Apple had it. No, night mode wasnt stolen by Chinese brands. US is just slow to innovate because they are very inefficent. Look at Apple, Google and Microsoft. Google Pixels are pretty good right? They couldnt even fix gamma change between 90hz and 60hz in their Pixel 4 and you have obvious problem with color cast. Apple has so much money they could buy some countries but still they dont make anything and outsource even screws for iMac Pro stand to some subpar brand. Microsoft still cant fix Windows 10..

"result of close collaboration between Xiaomi Corp. and Samsung." Samsung is manufacturing it, because only them and Sony have good enough fabs for such dense sensors.

And in terms of spying https://github.com/MiCode/ There you go, open source Xiaomi apps and kernel. Also you can unlock bootloader so basically you can do anything with device. You will still reply with something like "Chinese BAD, USA GREAT!". Where is source code of any iOS component? Oh, they even stopped give schematics of MacBooks to service centers where every chinese brand does it?

+Mike FL, thats 2 year old article, Xiaomi in 2018 entered pretty much every country in Europe and they didnt got any lawsuits. From 2017 they heavily invested into R&D and thats why you see this 108MPx sensor in this phone. "stealing US IPs" what a propaganda. They wont go into US because people believe in this. They made their own sensor in cooperation with Samsung!!! they made their own lens and in the same time Apple is using Sony 12MPx camera from iPhone 6S to iPhone 11 with CHINESE lenses developed by who? Of course chinese brand. Phones are built by who? Foxconn. CPU is manufactured where?... You get the point? Lets be real - US companies just dont innovate and they cry. How is 5G in USA? Bad China will spy and good USA will protect? Huawei is just so far ahead and US wont get $$$ so they cry. You can save this comment and in max Early 2020 you can be sure that Huawei ban will be lifted. You think it will be because they suddenly "stopped spying" or some US company has 5G stuff?

Ken Aisin: I'm currently using a Xiaomi Mi 9. It's got great specs for the price. However, the built-in apps, which cannot be uninstalled, are filled with advertisements. Most of these built-in apps also come with a privacy message which states that Xiaomi will collect your personal info. You have to agree to such non-sense before you can open such apps. Seriously, I will never in my life buy a Chinese phone again.

Ok so let me explain, basically you have three versions of Xiaomi Devices
India, China and Global. India and China has built-in ads and because of that they can be cheaper to compete with other brands (even heard of Tecno? They have more sales just in India than LG Worldwide). Usually India version are also worse in specs for example 10W charger instead of 18W because in this market even "$2" difference in price is huge. Global version is usually the best and doesnt have ads. Just look at box, if on box you have english names then its Global.
Next thing - privacy and spying. Xiaomi allows you to unlock bootloader so basically you can do anything you want with device. They also give you source code of kernel and apps here https://github.com/MiCode/ so you can easily check everything. Because of unlocked bootloader you can also sniff your internet to be sure that its private. If you dont want Google spying on you then with unlocked BL just install "MicroG" instead of Google services :)
