Sharif Sakr shows off "leaked images of HTC's forthcoming M8 smartphone," which, among its many new features, will sport two lenses "with two different focal lengths. One lens is wide-angle, while the other is at 3x zoom."

This means you can switch lenses to magnify more distant subjects without resorting to digital zoom. In the test set-up shown in the video above, which compared the dual-lens system side-by-side with a traditional smartphone camera (with both modules pointed at a test card around a foot away), the Corephotonics system outputted a clear 13-megapixel image regardless of whether it was at 1x or 3x zoom.

By contrast, Nokia's PureView cameras rely solely on digital zoom such that outputting a 3x magnified image entails a drop in resolution down to five megapixels. Corephotonics' system can also deliver smooth zooms, for example during video recording, by employing a mix of digital zoom and lens-switching.
