A brief addition to my notes about 'the impact of smartphones on the photography market'and'what's next? (Answer: Smartphone Supremacy).
There are not so many smartphones with an inch sensor:
- Panasonic Lumix DMC-CM1, 20 MP, with LEICA DC optics ELMARIT 1: 2.8 / 10.2 ASPH.
- Sharp Aquos R6, 20 MP, with LEICA Summicron optics 1: 1.9 / 19 ASPH.
- Leica Leitz Phone 1, 20 MP, with LEICA Summicron 1: 1.9 / 19 ASPH., Rebranding Sharp Aquos R6
- Sony Xperia PRO-i, 12 MP, with ZEISS Tessar T* optics, EGF 24 mm, F/2.0 + F/4.0 (mechanical aperture, but only two fixed values), however, the working area is around 1/1.31″ (diagonal is about 12.1 mm)
But over time, such 'big' sensors will migrate to more and more budget solutions, and in a few years, inch sensors in smartphones are likely to become commonplace.
The 'inch' sensors of these smartphones have a diagonal length of about 16 mm, the width of such a sensor is 12.8 mm, height 9.3 mm... This is larger than the sensor sizes in many digital compact cameras (with sensor sizes 2/3 ″, 1 / 1.63 ″, 1 / 1.7 ″, 1 / 1.8 ″, 1/2 ″, 1 / 2.3 ″, 1 / 2.33 ″, 1 / 2.5 ″, 1 / 2.7 ″, 1 / 2.8 ″, 1/3 ″, 1 / 3.2 ″, 1 / 3.6 ″, 1/4 ″, 1/6 ″, 1/8 ″, etc.) ... For example, in a modern, not cheap Nikon Coolpix P950 a 1/2.3 ″ sensor is used, which is smaller than in these smartphones.
The area of an inch sensor is only 7 times smaller than the area of a classic full-frame sensor with dimensions of 36 X 24 mm. Crop factor of such a sensor is Kf = 2.7X.
Approximately the same inch sensors used in interchangeable-lens mirrorless cameras Nikon 1: J1, J2, J3, J4, J5, S1, S2, V1, V2, V3 и AW 1... Inch sensors are used by some of today's advanced digital compacts like Panasonic Lumix DMC-LX15, Canon Powershot G7, SONY Cyber-shot DSC-RX100 Mark III etc.
The next step after the inch sensor can be considered the Micro 4/3 format (1.9 times larger in area).
In parallel with the increase in computing / processing power, such smartphones will increasingly displace digital compacts and the amateur segment of interchangeable-lens cameras from the market.

Why is an inch - 16 mm?
https://vasili-photo.com/articles/vidicon.html
There is a nuance - according to DPReview, this 20MP inch sensor uses only the central part (60% of the sensor) to obtain 12MP images.
That is, in fact, this is the equivalent of a 1 / 1.31 ″ sensor, since the rest is simply not used.

Thanks, added
sleepyheads would not be sleepyheads without such nuances
inch used in digital photography and video - the so-called. videoconov - 17 mm, as opposed to English 25.4 mm or French - 27 mm
Yes, put, finally, slots for SIM cards in the DSLRs. And no sensor race is needed.
there you will not get off with one slot.
What annoys me and does not suit me in mobile photography is the wide 24-22mm focal length ... The faces are skewed, the figures are disproportionate, the architecture is curved / oblique, the landscapes are sad / trouble ... ...
Well, for a long time already they have been shoving several modules with different focal lengths. From super-widths to 100mm + equivalent, they do not distort and are quite suitable for shooting
Not in all models. Usually the focal length of the main camera is 24-26mm, which is a perversion for me.
In running models (like redmi note), they shove a couple of useless chambers such as shirik and makrika, which are useless like a goat of milk. I don’t see any reason to overpay only for a telephoto camera, it’s better to spend money on a camera.
I expect a breakthrough from SONY competitor - Samsung ISOCELL GN2
50M Dual Pixel Pro
Arkady, Nikon Coolpix P950 has a sensor size of 1 / 2.3, not 2/3
Yes, that's right, ochapat. Fixed
Explain what is the point of putting the sensor on 1 "and using only half of its area (I'm talking about Sonya)
The point is that if you use it at 100%, the smartphone will “slightly” become thicker, like the size of the lens of a mirrorless camera divided by 3.
"I blinded him from what was."
We took a ready-made sensor, ready-made optics .. The thickness of the smartphone, again, limits, and competitors need a response faster ..
In my youth there were telephones that looked like a photographic camera from the back, now I need to do something similar without giving a damn about the thickness of the device, and if the quality of the photo is not inferior to 4: 3 and there is a removable lens, then it will be a bestzeller
