This prototype camera from Sony is designed specifically to film 2 images from one lens. Set to debut at CEATEC next week, the HFR Comfort-3D records at 240 fps through just one lens instead of two thanks to a new half-mirror system that takes left and right eye images at the same time, better for capturing fast motion and providing viewers lacking polarized glasses a 2D picture with minimal blurring.
As you can see instead of using two lenses which brings it’s own problems, focusing being one of them, Sony have decided to run with one lens and two recording devices, this in my opinion makes the 3D camera not only aesthetically pleasing but is far more practical and should allow smaller camcorders in the future.
I do not see how a single lens can capture an image offset to recreate 3D. Very clever if it works!
