The imaging system developed by graduate student John Hunt and colleagues at Duke University in North Carolina has no lens and instead combines a metamaterial mask or aperture and complicated mathematics to generate an image of a scene.
In addition to daily use as a "pan-focus" lens featuring a wide angle, fixed f8 aperture and shallow depth of field, it is compatible with manual focusing using a lever and capable of close-up shooting as close as 30 cm.
Dedicated lens rings allow for fingertip control of focus and aperture, while a DSLR-style Focus mode dial on the front of the camera enables easy switching between focus modes.
The lens' wide F2 maximum, 9-bladed circular aperture enable beautiful background defocus ('bokeh') effects to rival or exceed professional-class DSLR camera lenses.
This phone also breaks new ground in optics with 1080p video recording, f2.0 aperture and a dedicated HTC ImageChip on the main 8-megapixel camera and an ultrawide-angle lens on the front camera that lets you fit up to four people in the frame for a premium Skype experience.
