    Yes I totally agree with Brian as there really isn’t a reason to not want a global shutter, but as far as reasons to buy this camera, I would say that global shutter is just a nice upgrade. There are however, better reasons for me personally, such as size and form factor compared to dsmc2, also the rf Mount was the biggest selling feature for me

    Really? Then why does interlaced footage (i.e. captured in a PAL or NTSC camera without progressive scan) exhibit all of the characteristics of HFR? I had a Mini DV camera that had progressive capture, although the footage had to be stored in an interlaced format on the tape for obvious reasons. That, I think, is what you're referring?

    Yes. Jarred teased a breakout box with traditional I/O for that.

    I rejoiced at the death of tape recording media.
    I rejoiced at the death of interlaced video.
    I can't wait to rejoice at the death of rolling shutter!

    Filmed a gorgeous extended lightning show with spooky dead trees in foreground only to find it unusable thanks to rolling shutter. I should have realized it at the time, but for some reason it didn't occur to me.

    Now if we could find a way to kill HDMI in all forms, I'll die happy man.

    Yes, HDMI needs to go away from professional equipment. It should have never been there in the first place, at least not on cameras. We can probably thank the “DSLR Revolution” for that one. No one that has been in this business longer than the “HDSLR” or that has been in “zero fail” type situations involving video going from the camera to somewhere else would argue/lobby for HDMI on a professional camera.

    The global shutter should be a godsend for folk using long lenses for follows. With global shutter, an accidentally kicked tripod is just that. With rolling shutter, a carelessly hung toe on a tripod leg becomes a much more noticeable event. Please forgive the spots in the image. The lens is a Sigma 50-500mm f4-f6.3 zoom. They work like a vacuum cleaner and suck dust into themselves when the zoom is extended. The camera was Blackmagic's "big" URSA which shared a global shutter with the first BM4K ad the URSA Mini 4K. The band down the right frame edge was caused by a lens hood which went cockeyed on the front and I did not notice it. The clip was shot for the aircraft owner's flight test of a new smoke system which will replace marine flares carried in wingtip canisters.

    A shaky image with global shutter will still be ruined, as the shake cause motion blur. So good tripod heads preferably with high geared wheels will still be the go to solution for long lenses. and following shots. But the jelly effect the rolling shutter effect will be cured which is a big plus.

    That's pretty good, you might be right , seems like every artifact of film cinematography was "cinematic".

    High frequency vibration. Which at the moment will destroy footage from pretty much every camera on the market. Bad enough and it's actually not fixable in post even. If you've ever used an old 5D Mark II, roll on some stuff, and give the camera a good whack. Then try to stabilize and fix the footage.
    Since EOS R5 is the news of today - would IBIS alleviate the whack the camera problem? Or more likely smaller levels of bumping, vibration etc.
