TwoEyes VR is the most affordable fully spherical 3D 360 camera. They posted a couple of new 3D 360 videos, including a low light test. Check out the new sample videos.
Here is the first of the new sample videos. Notably it shows no flickering (an issue in their first 3D 360 sample, which was caused by the fluorescent lights in the room).
Here is the other new sample video, showing the camera's performance in low light.
