World's first AF cine lenses...
I don't know if these are HDMI 2.0 ( no version info given )
Available from B&H Photo : Pearstone 1.5' Ultra-Thin, High-Speed HDMI Cable with Ethernet (Black)
Keep in mind that the S1H firmware is currently at 0.4B, so lots of things are still unfinished on the camera. I expect that the final image will be even better once the firmware hits 1.0 and the camera is ready to ship. ( the same thing happened with the GH5 camera, where there were small issues with the preproduction cameras because the firmware was only half done )
This looks like Sound Devices answer to the new Zoom F6 32-bit Float recorder. It means that audio clipping will be a thing of the past when you've got 1,528 dB of audio dynamic range : https://www.sounddevices.com/32-bit-float-files-explained/
I expect Panasonic will have a FF EVA cine camera out within a year or so, but it's going to cost double what the S1H does. As long as you are willing to pay you can get rid of the DSLR style body.
I prefer a camera that can record 6K 10-bit continuously for 4 hours using 2 camera batteries (one in the battery grip) and 2 memory cards, and allows me to shoot everything handheld because of it's excellent IBIS system.
