Yes it is now possible to get a fully spherical 360 camera for around $50. The Opix360 Tetra is a 360 camera for Android smartphones that currently costs $52.73. With a discount coupon, you can even get it for less than $50.
Here are the specifications:
– two lenses, offset from each other
– Aperture: f/2.2
– Photo resolution: 2560 x 1080
– Video resolution: 1080p @ 30fps
– Supports Android 5.1
– compatible with Micro USB or USB Type C (I assume with an adapter of some sort)
I don’t have any actual samples. At this price, I wouldn’t be surprised if the resolution was interpolated. I would guess that the quality is marginal and probably webcam-like. But maybe it might be an interesting gift? 🙂 The Opix360 is available here. Use the code GBNovember to get an extra discount (while it lasts).
