Geez ! Quite a few 'phenomenons" for a camera. Must be from Mars:)

I was thinking the exact same thing while reading that list.

I'm guessing uncompressed HDMI out is pretty much wonderful when shooting video, especially when using an external recorder!

Tested this out over the past few days; so far there is nothing amazing to report. A little better in the blacks and highlights, but nothing significantly better than card recorded h264 files. I'm using a BlackMagic Hyperdeck Shuttle in ProRes HQ. Have I have more testing to do so I haven't given up hope yet.

There is one big problem however, no audio over HDMI (and I haven't found any menu settings that will alleviate this--if anyone has please let me know!). This makes syncing multiple camera shoots a serious pain. Recording audio and video would require an external recorder with analogue audio inputs like a Sound Devices Pix240 which is significantly more expensive than a BM hyperdeck, atomos ninja, or otherwise ($345 vs. $2800 for the hyderdeck vs pix 240).

The speed with which it captures a photo with the speedlight auto-assist beam is WAY improved! What I've been most excited about.
