Re: Is there a "best" phone camera out there?
The sensor size is not irrelevant regarding noise. A larger sensor can have larger pixels for the same pixel number - in turn larger pixels capture more photons per pixel, thereby there's less need to amplify the signal too much (which is one of the main sources of noise). That's why you have full-frame cameras with more or less the same pixel count of APS-C ones.
Canon recently released a camera which boasts a 4,000,000 ISO max sensitivity. How does it achieve it? Using a full-frame sensor with only 2.26 Mpx. Just, each pixel is very large, much larger than the usual full-frame sensor with a resolution of 18-24 Mpx, allowing it to collect much more photons per pixel.
