  1. The sensor is capable of 3 x 3 pixel-binned 3882 x 2912 at 30fps from full width and height of the sensor. Fujifilm simply did not implement this. Also it does not sound as enticing as "over-sampled 4K" in marketing. Also because of the 3 x 3 pixel-binning, the image will be very soft.

  3. Exmor RS is BSI and stacked. Faster readout because logic layer is now a whole dedicated layer (stacked), so more room for a substantial amount of low powered ADC working concurrently. Also DRAM can be stacked on an additional layer, but DRAM is not usable for video mode.
  4. Sony Semicon's Exmor RS line has now fully matured and will come in various sensor sizes - all 8K capable. One of the first to make the debut is a 45MP Micro 4/3 (MFT) sensor with 2.24um pixel size. More to follow.
  5. Yes it will have 8K because it will use the 50MP sensor on A1. It won't have A1 level AF but it will shoot 8K UHD 60P with 1:1 readout (slight crop).

  7. It's all 23.98P, for internal, external, compressed and ProRes RAW
  8. There will be several major firmware updates for FX3 to differentiate it from A7S III. They are not made available at launch partly because Sony do not intend to cut into A7S III sales too much.

    Read what's in the the link, you missed everything.

    Filters?

    That thread was from 2018. Technology has progressed far enough that we can now accurately replicate (not even "emulate") diffusion effects digitally that are indistinguishable from optical filters: https://videovillage.co/scatter/

    Filters?

    Other than polarisation filter, all filter effects can be precisely emulated digitally in post. This allows for much greater and finessed control and guarantees glare-free.
  12. Sony has just published a paper at ISSCC 2021 detailing the groundbreaking new 50.1MP sensor used in A1: http://image-sensors-world.blogspot.com/2021/02/isscc-2021-sony-501mp-full-frame-sensor.html

  14. Yeah but R5 has inferior sub-sampling method - it line-skips for 4K normal mode.
  15. Alexa's rolling shutter values have been scientifically and comprehensively measured by 3DEqualizer so that it can be accurately compensated for VFX use. They call it "Framewise Time Shift", the time it takes for the sensor to scan from top to bottom.
  16. Alexa's rolling shutter performance isn't that impressive. Alexa XT: 8ms in 16:9/4:3 2880 sensor mode, 13ms in open gate sensor mode. Alexa LF: 14ms open gate mode. Alexa 65: 15.6ms open gate mode.
  17. Sony's IBIS has very little room for the sensor to shift due to the restricted E-mount diameter (designed for both APS-C and FF!), smaller movements make it less likely to have perspective distortion.
  18. A1 readout modes: 8K up to 30P: Over-sampled from 8640 x 4860 full width readout. 17ms rolling shutter. 1/57s readout speed. FF 4K up to 60P: 2 x 2 pixel-binned from full width to 4320 x 2430, then over-sampled to 3840 x 2160. 9ms rolling shutter. 1/114s readout speed. 4K 120P: 2 x 2 pixel-binned from 7680 x 4320 window (1.12x crop) to 3840 x 2160. 8ms rolling shutter. 1/124s readout speed. S35 crop 4K up to 60P: Over-sampled from 5760 x 3240 window (1.5x crop) to 3840 x 2160. 11ms rolling shutter. 1/90s readout speed.
  19. That's BS. Both R5 and A1 shoot 8K using full width of the sensor. On R5 it has to be 8K DCI mode (8192 pixel wide). 8K UHD has a 1.06x crop. A1 oversamples from 8.6K and it only shoots 8K UHD so no crop at all.
  20. A1 seems to have insane rolling shutter performance for video. Only 2ms for 8K 30P, thanks to DRAM being made available for video read-out modes for the first time ever. In stills mode, this increases to 5ms @14bit readout.
