Additional Information: Generally speaking, a camera rig is needed, which would connect two Sony A7RII cameras. The cameras need to be connected bottom-to-bottom in a way that there is no space between them. This is needed to get the correct distance between the two lenses, which is neccessarily needed for proper proportions in the final video output.
Update:
1. The 3D Model of the camera will be provided (https://www.youtube.com/watch?v=UOLymK2qRCM).
2. It must be possible to mount the rig on a c-stand. Probably the most stable solution would be if the rig had a 20cm long and 16mm thick tube on it's bottom, so we could lock it in place with a c-stand grip head.
