I have a sony a7rIII and a 1.4 Gmaster 85 lens. Things were fine, then I bought a 24-105 lens, played with it for several months, then I put the Gmaster back on and now I can't change the aperture in manual mode. If I put it in A priority it seems to be ok. But I rarely use that. Has any one seen this before. 'can't figure it out.
I want to control the A7RIII by using the USB multiport cable and get the live image of the viewfinder over HDMI.
We use the A7RIII on a drone to take aerial pictures and movies.
We have to use the USB multiport (USB PC Remote) in order to take pictures and to start/stop video in Manual photo mode.
This will not work by using WIFI.
This works perfect as long we're not plugging in the HDMI cable into the camera.
When we use the USB multiport in combination with HDMI, the HDMI feed goes to black when we start recording.
Taking pictures works like it should be.
I think I've tried everything to solve this problem, but nothing seems to work.
Somebody with the same problems?
