Hi .I'm currently using canon g25 and Panasonic x920 cams for my recording studio, well lit live room.

I'm looking at getting a few cameras where I can control all of the manual controls of the camera remotely . (The x920 can't access it's wifi remote options unfortunately whilst outputing HDMI ).
I was looking maybe at the rx100 m5 , canon g40 or Sony rx0.
Obviously I think the g40 would give the best manual control but I'm also interested in 4k for virtual zoomed in 1080 hidef inputs from one camera lock off.
Does anyone know if you can remote control the aperture of the rx100 with wifi ?
Would you choose the rx0 over the rx100?
(The rx0 I notice can't record 4k internally ,which would be good for a back up ).
