Black Magic Pocket Cinema 6K

Appreciate any  impartial reviews, impressions and endorsements of this platform, especially re: autofocus speed and housing recommendations

Hello.
I have this camera and I am very happy.
The positive:
6K, different resolutions, raw, very good definition and colorimetry.
The negative: poor battery life. No stabilization.
I use it in a Nauticam underwater housing with a Canon 16/35 2.8 lens and a nauticam 180 glass dome.
also a canon 100 macro with saga front.

The positive:
It can hold a 500g Sansung ssd disc inside and thus save on expensive cards.
It also has a compartment for lithium batteries that connects to the camera and thus have more 
than an uninterrupted hour of operation under water.
The underwater housing is superbly designed and you can access all the necessary functions underwater.
The only negative is that it is not a stabilizer camera and you have to have good diving 
and filming technique.
For macro I use articulated arms as a tripod and they go very well!
6K in fulframe and with a 100 macro is very shallow depth of field, but the macros are incredible.
It is an expensive equipment, but I guarantee that with 6k I will have equipment for a long time.
Any questions I will be happy to help you, since I also had many uncertainties before 
deciding to buy a new equipment.
All the best!

Appreciate the advice, Azul!
