I have seen a lot of posts about this but nothing resolves it. I have an A7iii on a DJI RS2, and a Feelworld F6 Plus. Only when the camera is connected to the gimbal, when you press record the monitor goes off. This doesn't happen with the same set up on my A7ii. Really hoping someone can shed light on how to resolve this as working without the monitor today was horrible.
With Firmware 3.0, the α7R III and α7 III (as well as the Sony α6400) now have a built-in timelapse intervalometer. Here are some tips to get the camera set up for making a timelapse using the built-in controls. There's a lot of trial and error in making a timelapse.
