Just watched... These type of PROs ain't used to this level of devices, so they don't even realize Camera2 API exists in order to have sharpness under control:
Pure marketing. Not the best skillful pro to put behind a mobile device like this one is :- )
Camera2 API is for Android.
iOS camera API does not yet allow sharpness/noise reduction control in either photo or video mode.

Can the background colour be a dark neutral gray instead of navy blue? It's still blue light and may be too much of a visual stimuli, defeating the purpose of a dark theme which is often used at night.
Also can the forum width be a bit wider? I find 80% still leaves too much blank space.

This is the sensor
https://www.gpixel.com/products/area-scan-en/gmax3265-3-2-μm-65-mp-global-shutter-image-sensor/
It's rated at 11 stops dynamic range. Unless it does some dual gain (re-wired) magic, I am not sure how it will push image quality to better than mid range DSLRs/Mirrorless, regardless of bitrates.
10 stops.

Based on an industrial sensor https://www.gpixel.com/products/area-scan-en/gmax3265-3-2-μm-65-mp-global-shutter-image-sensor/
Image quality is shit.

I tiny 1\2.3 inch 23mp sensor (Sony IMX667) will give us even worth DR than the previous GoPRO. Why oh why do they keep using those tiny puny sensors? Why not put an IMX700 (same as in Huawei P40, 1\1.28 inch) in there?
If new Osmo Action will use IMX700 or similar, they will crush GoPro.
Sony Semicon imposes strict licensing restrictions, one of these restrictions is that certain sensors can only be put in specific products (eg. mobile phone only).
This is why drone cameras from Autel/DJI have only recently started using the more than 3 years old IMX586 sensor.

Leaked image of Canon engineer working on R5 firmware update:

The guy who did the teardown uploaded new FLIR images showing the temperature after the "overheating" shutdown. Highest spot was 64C.

Yeah, a simple qualifier and a small amount of blur got rid of the moire:
It must have happened by coincidence - the texture of the t-shirt and the sharpness/focusing of the lens produced just the right amount of high frequency detail that the sensor could not resolve.
Maybe next time you can ask the subject to be shirtless, moire-free guaranteed and you'd get more views 😆

Sony A7S III

Just now, Llaasseerr said:I considered the dual gain architecture of the ALEV III. If you can point to a link of how the in-sensor highlight rolloff works, I'd be interested to understand. But it makes more sense to me that the high gain and low gains readouts are merged into a single high dynamic range linear image before being converted to log.
It's not done "in-sensor". The two readout paths are both derived from 14bit ADCs, they are processed and merged by a 16bit ISP. Roll-off as well as other ARRI colour science processing happen when doing this 28bit > 16bit conversion.

1 minute ago, Llaasseerr said:It's a common myth that there is "highlight rolloff" from a sensor. It reads linear light values and hard clips at a certain point - there is no highlight compression, unlike with film negative. Highlight rolloff is a product of how much dynamic range a sensor captures combined with the filmic s-curve applied either in-camera or in post.
If you want more clarification on this, here are some links:

There's absolutely highlight roll-off on a digital sensor with dual/multiple gain readout. The roll-off is applied when merging the high gain and low gain readout path, which is how ARRI does it.

52 minutes ago, Kino said:This is some of the best footage I have seen from the camera. A7SIII colors and DR rival 16 bit linear RAW from F5/F55 from a few years ago, all of that in a 10 bit 4:2:2 codec:
In the hands of a capable shooter, the lack of internal RAW is no limitation at all.
It has good cinematography, but it doesn't show a lot of DR, especially in highlights (F5/F55 don't have much highlight DR either, around 6EV).
Pay close attention to the way the sun and the surrounding clouds were blown out,

Off topic but relevant here, R5 rolling shutter official test results have been published:
https://www.slashcam.de/artikel/Kurztest/Die-Rolling-Shutter-Werte-der-Canon-EOS-R5.html
8K30/4K HQ: 16ms (indicating a 8K 60fps readout)
4K normal 24-60fps: 10ms
4K 120fps: 8ms

Is there any mention of improved recovery time? That's the other factor. Is the crazy recovery times due to temperature or firmware? If it's firmware, there's no hope other than Canon to fix it.
He shot 15min 8K All-I (no overheating warning showed up). Turned off for 10min, then kept going non-stop till the 512GB card was full.
But, when he shot 20min 8K until the camera auto shut off, then cooled the camera to ice cold with an AC, he could only shoot additional 5min of 8K.
FLIR camera showed the CMOS at 44C and CPU/main board at 69C when the camera auto shut off.

This thread details the teardown process, modifications made and some important findings:
http://c.tieba.baidu.com/p/6848700307?pn=1
He replaced the two thermal pads that did not fully cover the CPU with a dollop of thermal paste and noticed significantly better and more even heat dissipation.
Most important finding: despite the temperature drop and improved heat dissipation, 8K/4K HQ still cut off at 20min mark, suggesting a firmware limit is also in place.

A7S III colour science is certainly improved and offers a much better starting point for colour grading.
Here are some samples matched to ARRI Alexa with minor adjustments, using "CineMatch" sensor matching algorithm, the A7S III sensor profile is still at beta stage.

Mostly a marketing tool so people perceive it as on par with those CineAlta cameras.

You can download a sample, shot at 0EV and see for yourself.

It's just marketing BS for frame-blending HDR.
Newer iPhones do this for 4K 60P (2-frame blended from 120P).
