    Thanks!

    Do you have a definitive answer to the question above about 4K/8K? ;-)

    Are both obtained with binning?

    WOW that's really impressive performance, it's an amazing feat that a 12k sensor can be read so fast

    (thanks again for the figures, I added them to the table, including the 2.4 numbers)

    With the 7.0 update that has just gone live on the Blackmagic site, the read out speeds on the 12K are now:

    12k 17:9 -> 15.55ms
    12k 2.4:1 -> 12.27ms
    8k 17:9 (full FOV) -> 7.78ms
    4k 17:9 (full FOV) -> 7.78ms
    6k Super16 -> 7.78ms
    8k 2.4:1 (full width) -> 6.13ms
    4k 2.4:1 (full width) -> 6.13ms
    4k Super16 -> 3.89ms

    Hey Sam!

    Anyone has the Canon R5 measurements in Full Frame and in the Crop Mode (oversampled from 5.1K)?

    Cined measured 15.5ms in full frame so it should be less than 10ms for the crop mode, right?

    But I'd love to also hear from someone who has it or has read a test somewhere...

    I don't have a test for that one, and I haven't looked for it either: it's not a camera I would consider using. The new cined methodology looks good, I'm not sure the numbers can be compared with mine but I'd take that measuremena as a strong sign that it has reasonably good RS.

    The rolling shutter tests from Slashcam for the R5 report essentially the same numbers as CineD:
    https://translate.google.com/transla...on-EOS-R5.html

    8K or 4K HQ (up to 30 fps): 16 ms
    4K regular (up to 60 fps): 10 ms
    4K 120 fps: 8 ms
    HD (up to 60 fps): 10 ms

    They didn't test the APS-C crop mode, but given that this mode is always oversampled from a 5.1K full pixel readout, the rolling shutter times should be proportional to those for the 8K readout modes, which would put them under 10 ms.
