    (I read this and downloaded the clip, but haven't had time to run the numbers, and won't have it for at least a week more, maybe two)

    Looks like this test vid might work for the GH5's 4K numbers. Wish they'd done 1080p modes too.

    Finally got to measuring this. Great performer indeed: 10.8 ms (same as in 1080p S35)

    I'm curious as to what the T7i's rolling shutter ms is. How do you measure it. The 1DX II seems to perform very nicely.

    Okay please note but these are 25p (I hope that's okay) from my RX100-V, which is supposed to be a noticeable improvement on the RX100-IV, so let's see if that's true...

    My upload limit resets early Sunday, so they other two will be a while I'm afraid. (I can WeTransfer them if you'd like, just PM me an e-mail address to send them to.)

    BTW this is quite interesting - looks like GH5 rolling shutter is ISO-variant for stills, but possibly not for video (only 6k video was tested)!

    (The 6k one must come from a video stream.)
    I wonder which other cameras do this and if any do it for video?
