    The sensor does 120fps at Full Res, 12-bit, which would be great for both Photography as well as for Shooting RAW video. 

    "Each pixel readout method deployment for the specific mode (1) Normal, (2) Phase difference, (3) Single pixel, (4) HDR ◆ H driver, V driver and serial communication circuit on chip ◆ 10 bits / 12 bits A/D converter on chip ◆ 14 lane (8 lane + 6 lane) SLVS-EC output ◆ R, G, B primary color mosaic filters on chip (Quad Bayer structure)."

    I am not sure what this HDR in (4) is supposed to imply? Will it have better HDR, and perhaps something on the lines of what's on Smartphones, given the much faster readout?

    Also, why it Quad Bayer mentioned? For a 20MP sensor? Will it UpRes, like on QuadBayer sensors with larger CFAs? 

    The HDR is simultaneous dual-gain readout of each pixel, it's for stills mode only.

    Quad Bayer for this sensor is 2 x2 OCL for each pixel for cross-type on-chip AF.

    What the specs never say is the bit depth used to scan the sensor. When stills are taken one might expect the full bit-depth is used (14-bit?). But in video mode, to reduce rolling shutter, a read-out mode with reduced bit-depth may be used. For 8-bit log or gamma-corrected recordings a 10 bit (lineair) read mode might be used. If that same 10-bit linear mode is used to create a 10-bit log, the quality wouldn't be much better than with an 8-bit log except for reduction of round-off errors.

    Sony sensors use linear 12bit ADC readout in video mode.

    There’s another new Fuji Rumours post about the “monstrous” X-H2 in 2022,
    predicting a new sensor & processor for 8K.

    What new APS-C sensors will do 8K video?

    and will any of them do 59.94p at 8K?

    There are two prototypes being developed, one is 8k capable and the other is not.

  4. Based on information from multiple sources, Canon originally planned to announce this camera as R1. However the Sony A1 was completely unexpected and too competitive. So Canon made a strategic decision to reposition this camera as R3, buying time to develop R1 that can truly compete with A1.

    The pixel-binned image from the GFX 100 is very good. Not soft, and aliasing not too bad either. One of the best pixel binned images.

    GFX100 and GFX100S do not use any pixel-binning. Horizontally it uses full readout of 11604 pixels (possible because of Sony sensors column-parallel ADC), vertically it line-skips 2/3 resulting in 4352 pixels. Then this 11604 x 4352 image is over-sampled to 4K.

    Define “very soft,” because I’ve seen my stuff on theater screens which have only ever been 2K, and it looked fantastic. 3883X2912 is very comfortably over sampled if delivering a 4096X1716 DCP, even if it’s “soft.”

    You misunderstood.

    Pixel-binning has a strong anti-aliasing effect (blurring). Especially so for a 3 x 3 pattern.
