The one downside of the higher resolution camera was that it eats batteries.
I posted the other day about my excitement over the new Ricoh Theta V 4K/360° camera that has recently been released, and then my disappointment on reading about some of the details. This ultimately led to me cancelling my pre-order for the camera.
But it also led me to play with Google Cardboard, which is a deliberately cheap design for a Virtual Reality headset. In particular, video taken with the Theta and uploaded to YouTube can be viewed using Google Cardboard, and as you move your head, the frame of view moves accordingly. It is an amazing immersive effect, even with the crudest resolution of video.
