Just a confirmation,...
I got to test a K-1 with my Atomos Shogun via the HDMI connection.
Besides still doing the wrong frame size and frame rate output from the HDMI port, also ran in to an issue where, even with all the on-screen overlays switched Off in the menus, the artificial horizon and focus marker for face recognition were still present on the HDMI output.
So, if it's true that the KP and K-1 are getting firmware to re-enable Sensor Shift in video (YAY!), there is still work to be done before the K-1 reaches it's full potential for HD cinematography.
My 'best guess' is that on all Pentaxes, the output from the sensor is routed to the LCD driver, and then to the HDMI port, so the HDMI output gets whatever is needed to drive the LCD, rather then a clean output.
That would also explain why the HDMI output is at a different frame rate to that the user has selected to record, such as outputting 30fps when the cameras recording 24.
Ideally ( And iff anyone from Pentax is reading this,...) the output to the HDMI should be routed directly from the sensor engine, at the user selected frame rate and frame size, and entirely separate to that which is being fed to the LCD.
That way, iff they really wanted to, and iff the HDMI hardware is capable of it, a K-1 could even output the whole sensor output as a larger frame size, say 4K, without doing any writing to the SD card.
- "the whole sensor" - 4:3 area with Anamorphic lens,... or crop to 16:9 area for 'UHD'
It's a lot of 'iff's', but, it could mean a firmware fix to catch the competition - Sony's A7s sold perfectly well without being able to record 4K internally while outputting 4K to the HDMI.
