4K 24-60P and 4K 120P have almost the same level of sharpness and detail. And 1080P is not supersampled, but pixel-binned from 24-60P and line-skipped from 100-240P.

Someone dissembled R5 and found barely any heatsink and shockingly there was no TIM (thermal paste).

Regarding the so-called "16bit linear RAW" 4264 x 2408 60FPS HDMI output, it's actually derived from 12bit ADC sensor readout, then dithered(upscaled) by the DSP to 16bit.

It was shot in 4K normal. R5 8K/4K HQ: 21ms R5 4K normal 24P to 120P: 8ms A7S III 4K 24P to 60P: 15ms A7S III 4K 120P: 8ms

R5 has better rolling shutter than A7S III:

The white dot next to the AF assist lamp is actually an XYZ sensor (visible light + IR sensor) to help improve AWB accuracy.

Context: This was tested in Florida under direct outdoor sunlight with ambient temperature of over 38C. A7S III lasted 23min shooting 4K60 R5 lasted 34min shooting 4K30 HQ.

None of the 1080p modes on A7S III are supersampled from full sensor readout, 24p to 60p are pixel binned, 120p is pixel binned and lineskipped, 240p is futher pixel binned lineskipped (to 1420 x 804)

XAVC R5, not RS. It's not a codec. The camera records XAVC full flavour internally and output X-OCN RAW to the Sony R5 recorder

It's called XAVC RS.

Shoot HLG, expose conservatively and push the shadow/midtone in grading. HLG has great latitude and BW helps mask the slight chroma noise.

The 2x2 pixel-binning in 4K normal and hfr mode has a softening effect, but it can be sharpened to be almost identical to 4K HQ (Oversampled from 8K).

Yes, with Bayer sensors, 1:1 readout is always softer than oversampled readout. Strong OLPF that combats moire can make it even softer.

Oversampling minimises moire/aliasing, it does not directly correlate to better DR.

AP's new logo after this:

I’ve seen one of the cooling solution prototypes Smallrig is designing for R5, it’s not only a cage like in the picture. They had a 60mm Noctua fan mounted side by side at the bottom of the camera, with a battery plate at the side that can also power the camera.

Smallrig will actually release a cooling accessory for R5, it's not just a cage. And the lens in the picture is Sigma 24-70/2.8 RF mount.

It's a 1.1x crop from 4240-pixel wide sensor for 1:1 4K UHD readout, this crop is there from 24p all the way up to 120p.

BMD patent document on the URSA 12K sensor design: https://patentimages.storage.googleapis.com/88/08/39/428dbbc9e5dfca/US20190306472A1.pdf Actual CFA pattern: In the document, it specifically discusses colour-aware pixel-binning to increase sensitivity and double framerate, at the expense of lower resolutions. So the "oversampling" mentioned in marketing is without doubt BS, at least for full FOV framerates higher than 60fps. Because if it oversamples from full 12K, then the oversampled modes cannot exceed 60fps which is the full readout max fps. Maybe there's a feature similar to R5's "4K HQ" mode.

This is the CFA pattern of the URSA 12K sensor: 6x6 block instead of traditional 2x2, 18 RGB pixels and 18 white/transparent pixels, which improves SNR a bit but reduces resolution. So the optimal shooting mode will be 4K (full RGB info without interpolation from 3x3 pixel-binning), 8K will be softer, 12K 1:1 will be very very soft.

Yes I invented this 12K sensor, which is precisely the same size as RED Komodo at 27.03mm x 14.25mm, and exactly double the horizontal and vertical resolution. And who made the RED Komodo sensor?? 😉 Ok fine, this 12K sensor is a custom version of Canon's 120MXSC, operating in an ROI mode https://canon-cmos-sensors.com/canon-120mxs-cmos-sensor/
