How long will the XT3 be able to shoot 4K video ?
I shoot lots of live events where I need 90-120 minute recording.
And does it record 10-bit internal like the GH5 or externally like the new Z-mount Nikons ?
I like to keep things simple and compact, so internal recording is always my preference.
...Or logical. They've pretty much gone as far as they can go with the m4/3 format, so it's time to expand into the FF market. There are many people that will never shoot with a m4/3 camera no matter how good it is, so bringing a lot of the GH5 tech to a FF camera is a very smart move. Panasonic can be the master of video on both m4/3 and FF formats.
I also hope they implement the G9 high-resolution multi-frame imaging in the FF camera, so a FF camera with a 35 Mpx sensor could create a single 140 Mpx high resolution image in camera. ( Panasonic is using IBIS sub-pixel positioning of the sensor to create this image, so Canon is out if it has no IBIS tech )
