    Thanks for that! It took me a while to process, but what a nice bunch of test clips
    The 180 shutter is just in case it matters, but it really shouldn't.

    Measurements, in ms:
    GH4 4K 24 --> 22,7
    GH4 UHD 23 --> 22,6
    GH4 UHD 24 --> 22,1
    GH4 UHD 29 --> 22,7
    GH4 FHD 23 --> 13,6
    GH4 FHD 24 --> 13,6
    GH4 FHD 29 --> 13,7
    GH4 FHD 60 --> 13,7
    (always average of 2 measurements, except for 4K, where I took 3 instead)

    I'm summarizing this as
    GH4 4K/UHD: 22.5 ms (23.2-22.3-22.7-22.7-22.4-21.8-22.4-22.8-22.6)
    GH4 1080p: 13.7 ms(13.7-13.5-13.1-14.0-13.9-13.5-13.5-13.9)

    Why is this in HDLR section? This isn't HDSLR issue at all as FS series have rolling shutter too. It's a CMOS sensor issue. And none of these cameras except 5D are DSLR anyway

    Well, DSLR is an obsolete term, I think of it as "stills cameras that also shoot video". And with the exception of the BlackMagics that's what I have tested.

    No other section would be better, anyway, since there's no "all cameras" section.

    But F65 is there in list. Costs more than F5 and Alexa.

    By the way why is F65 there? It has global mechanical shutter.

    I haven't ran the numbers for that second list in the bottom. The F65 is there because Squig found some numbers for it somewhere in the internet.

    aren't there various options to choose from with the F65? I thought there is a rotary (global) and rolling shutter version...

    It'll be nice to see the Sony A7s results compared in its other recording modes:

    1. FF in 50/60p
    2. APS-C in 24/25/30p
    3. APS-C in 50/60p

    I would love to contribute but my unit hasn't arrived unfortunately.
    Such reference would be really useful since Slashcam has revealed that the APS-C mode does better in resolving details compared to FF 50/60p mode, which of course was only observed a non moving shot.
