Apple's rumored dual camera setup gets showcased in this demo concept video
In January, a patent application was published by Apple, giving us a glimpse into what a dual-lens camera interface could look and feel like on iOS devices. It was an interesting turn of events, considering the rumors of a dual-lens camera coming to one or several of the iPhone 7's variants. The patent describes a dual-camera system consisting of one standard wide-angle lens (similar to the one that's in the iPhone today) and a second telephoto lens capable of capturing zoomed-in photos and videos.
Apple is toying with some interesting ideas that will let you capture more special moments.
For example, a parent could capture a video of the moments before the candles on the cake are blown out using the standard wide-angle iPhone camera, and then tap on the screen to open a split-screen view and activate the telephoto lens for a close-up shot of the exact moment the candles are blown out. The zoom system uses a lens with a longer focal length instead of software magnification, which makes the zoomed in image crisp and clear. Both cameras can be used separately, with each one capturing video (even in slo-mo) or one capturing video and the other taking photographs. The resulting footage can be stored independently, or merged together in an artistic way.source: MacRumors
