4k120 without crop

Its pixel binned at 120. Sensor can do full res 120, but the CPU is the bottleneck.

they just laid the foundation for the future sensor tech.

They did it in machine vision few years ago. Its a refined scaled version of that.

"Shutter speed is freed from the limitations of conventional mechanical shutter image sensors and achieves a maximum shutter speed of 1/80,000 second (1/16,000 second during continuous shooting), making it possible to capture at high speed without any distortion."

Powering the camera is the Bionz XR processing engine, promising eight times more power than the a9 Mark II’s processor."

INSANE !!!

 

I thought 1st April arrived late or early.

The current CPU used since A7RV is quite hot (literally), look at overheating E1/A6700/A7CII..

It definitely need to wait for the next gen cpu to catchup in terms of performance and thermal issue.

But A1 and A7SIII finally getting firmware update, SIII finally get 24p and breathing compensation.

Almost all major prosumer Sony cameras overheat I guess. Maybe the ones where the node size is too large, that lacks a heatsinks, or fan or some other issues.

Sony doesn't care for overheating. This one shoots 120fps at 24MP, but for only 1.5-1.6 seconds or something. Guess that means that their RAM isn't really huge. Also, it could probably be used to cook in the winters during shoots 😁

Making a CPU with state of the art node doesn't make a PR fenzy, "World's first" in sensor tech, does. They really really want to show they're leader in sensor tech, all else is secondary.

They certainly are that.

This technology is the future and will result in the end of mechanical shutters once it becomes more broadly available and common.

The only thing is, I feel we have peaked a bit. Sony a1 still does everything I need and it's hard to see what on the specs sheet needs to change. Of more value to me would be a big change in shooting concept and more imaginative design, rather than this game of constantly escalating numbers and speeds.

It is just being announced live by Sony.  At only 24mp there will be no 8k. It will be interesting to see the video specs.

They are holding back on the video side but it's still a big step up from the original a9 and 9 II. It has S-LOG for starters! 🙂

The sensor does 6K but unlike Fuji, Canon and Panasonic, Sony have chosen not to give us it. Codec is capped to 4K, oversampled.

Surely with a global shutter design, the sensor is destined for cinema cameras, which could be why we don't see the full capabilities of it in the a9 II. Market segmentation, and battery power / heat management / image processing limits all at play here.

It's still a very exciting tool and clearly a step up from the a7s III.

However I am keen to see whether global shutter hurts low light performance, and dynamic range, when the first reviews come out.

PS - this is the sensor I think the Panasonic S1H II will have

Should have. Sony usually doesn't share its best sensors with others. And they have a particularly bad disdain for Panasonic 😁😁😁

If any new FF Panny is coming within the next 2-4 months then surely it will not. Unless their relationship has changed?

But unlikely I’d have thought because if Sony are holding back for their cinema line, they are not going to allow the likes of any new S1 line to eat their lunch.

Some of the features not mentioned during the press release but appeared in Chinese marketing material:

  • Multi-frame RAW noise-reduction (Combining up to 32 RAW burst stills for one noise-free RAW still)
  • Custom LUT import for video
  • Lens breathing compensation in video mode

It's expected to ship in China around end of January 2024. Early testers commented on the dynamic range to have taken a "slight but noticeable" hit due to global shutter design, hence the limited native ISO range of 250 to 25600.

If its noticeable its not slight. Again, its new for us, but its not new in CMOS sensor industry. Global shutter is usually capped at almost 12 stop DR. With smaller pixel will be even worse. Even Chinese are making them. But the question is why they didn't use the hybrid solution that a single sensor can use both rolling shutter for maximum quality, and global shutter for speed. They have lots of patents for that solution.
