Camera Sensor Limits

Discussions center on the physical limitations of high-resolution camera sensors in small sizes, debating factors like pixel pitch, diffraction, sensor size, low-light performance, and noise over mere megapixel counts.

The cameras usually have better sensors, not just the resolution.

Higher res doesn't matter - they need better low light performance

There are fundamental physical limits at play. Smaller sensors, with smaller pixel size are diffraction limited more quickly. This new sensor has a pixel pitch about one eighth of what a modern APS-C DSLR has. That sensor would be diffraction limited at around f1.4. Most camera systems are more limited by lens resolution than diffraction. Fast lenses like those found on smart phones often have issues with optical aberrations. The lens quality issue is both a financial and technological one. It i

Why do we need so many pixels? Aren't lenses way more important?

Please try to make HN a corner of the web where participating benefits everyone. Perhaps a breakdown or rationale as to why a camera sensor of this resolution will never be that small?

What's the difference? (Other than needing a really densely-packed sensor, of course)

more megapixels/better pixels require bigger sensors, thus, the optics have to scale accordingly too.

Sensor size matters more than pixels (or photosites is you count individual cells forming one pixel)https://www.androidauthority.com/camera-sensor-size-1095299/

Hi OldSchool,Thank you very much.In terms of pixel density: You may have noticed that the "megapixel wars" have pretty much stopped. And even the sensor that I've been using for nearly all of my "world record sized" is the 18-megapixel APS-c (1.6X "crop") Canon sensor (550D, 7D). The 7D is nearly 4 years old! Only in recent months has Canon released a camera with smaller pixels (the 20 megapixel 70D). Why?One major reason is that lenses can't reso

I think the limitations are in optics and the signal processing stack, rather than the CMOS sensor. A better lens can go a long way.
