    Thanks! That's a reasonably fast rolling shutter, so, one less thing to worry about. It definitely seems you have a winner in your hands, congratulations. Can't wait to get my p4k!!

    Very fast for 1080!

    Would be worthwhile doing "merely" 1080 for high paced action scenes when resolution matters a little less, but limiting the rolling shutter could be handy

    Captain Hook, thanks for releasing those... very refreshing to see a company be pro-active with getting those numbers out there.

    One question... given that the camera uses the same Sony sensor as the GH5s (which I've repeatably measured as sub 12ms for 4096 by 2160, a 25% improvement over the Pocket 4K), are these numbers final, or something that is addressable over time, much as the original RED camera slowly improved the readout speeds over firmware iterations?

    Regards,

    Jim A.

    The p4k has better-than-expected battery life, so maybe the sensor is working at a slower clock speed than in the GH5s

    BTW maybe you could calculate the EOS R rolling shutter at 10:20 into this video (note preceded by 1080p test):

    Assuming it's shot at 25p.

    I'm not sure the camera is on a tripod on that test. If it was a more interesting camera I could try to measuere and see if there's more variance than usual, but for this one, I'll just wait for better footage...

    I don't see the download button

    (maybe it's disabled, maybe it's moved from where it used to be years ago: I haven't used vimeo in a long time)
