I am using a Sony a7r2 with the 16-35 f4 and have a weird issue with triggering the camera with IR on a drone
I can trigger the camera with infra red if it’s handheld or on a tripod but as soon as I place it on my gimbal it will only fire in manual focus mode.
I’m using a servo to trigger an infra red and if I tilt the camera down about 45 degrees the camera will fire in autofocus, however if I tilt it up it won’t fire.
I have tried every setting imaginable and also shielding the IR with no success.
I am using the exact same set up that I had with a Sony A7R, it fired every time in autofocus with the Sony A7R, but not with the Sony A7R2, I’m forced to use manual focus.
