Sensor technology, is a game changer coming?

apefos

The today sensor technology is reaching the limits of evolution. Color, noise, low light, dynamic range, resolution, fps, rolling shutter, everything has improved great.

So it seems only a new technology can make things better from now.

So the question is: will a new sensor technology come soon? Are the manufacturers developing a game changer sensor technology?

Vitaliy_Kiselev

Yes. It is called AI :-)

And overall cameras production will drop and drop, as in the flood of AI stuff it'll be much less reason to buy camera.

apefos

Maybe the famous people will sell their image rights so AI developers can make movies with them using nvidia gpu.

I did a research about the organic sensor and it seems it is currently being developed with good results, but no release date yet.

“If we [make a] new camera, we can choose that kind of sensor. But it’s kind of an R&D matter. So it is not [certain] that we will use that sensor in the next camera or not.”

Well, as always they never tell you the whole story. It could be coming in a Panasonic camera this year and they would never tell you until it's official.

Dual layer sensor for low noise and better dynamic range:

Old stuff, but good to know: dgo sensor - dual gain output:

Interesting

Sony imx490 hdr sensor, 4 different exposures at same time, merge into hdr video:

Different manufacturers are showing hdr sensors but not for mirrorles camera yet...

apefos

the technology is ready to release a mirrorless camera with hdr sensor to solve the shadow/highlight problems and avoid using log profiles.

they just need to implement a triple native iso 800/3200/12800 or 640/2500/10000 and also implement a triple gain output, all at the same time to get 3 different exposures for each frame and then merge into a single frame inside camera.

dual native iso and triple native iso cameras already exists, and dual gain sensors already exists. hdr sensors for automotive and security cameras already exists.

so the question is: why are the manufactures avoiding to release a mirrorles or cinema camera with hdr sensor? maybe the log profile cameras are selling good and they want to make profit from it and just release the hdr sensor when the sales drop significantly...

apefos

there is a rumor about a S1H Mark ii with hdr sensor, but it seems to be a "i want this" rumor, instead of a real rumor:

@apefos

Rumors from that website never turn out to be true!

apefos

Yes, this rumor is just people wishing...

so let's talk about wishes...

imagine a camera with triple native iso: 800 / 3200 / 12800. the first iso 800 can vary from 400 to 1600. the second iso 3200 can vary from 1600 to 6400. the third iso 12800 can vary from 6400 to 25600. all can vary in 1/3 fstop. each native iso deliver a frame, so you can get 3 simultaneous frames to merge in camera. and you can choose each iso to do the best combination for each scene. this would be a dream, the perfect camera, because you could adjust the middle exposure first and then how much to lift the shadows and how much to preserve the highlights...

if this camera become true someday it will be expensive, because this is all that pro people wants... and maybe the M43 will do this for the low budget people...
