The ZenFone AR isn’t the only feature-packed handset that Asus is showing off at the CES in Las Vegas. The Taiwanese mega-manufacturer also unveiled its ZenFone 3 Zoom , a phone that uses a pair of lenses to provide optical zoom capabilities without the moving parts and added physical depth that this functionality usually requires.
The Zoom looks out into the world via a pair of 12MP cameras. The first has a fairly standard f/1.7 aperture and 25-mm wide-angle lens, while the second camera has a 56-mm lens. Operators can switch on-the-fly between the 25-mm primary camera and the larger unit for an effective 2.3X optical zoom, which should come in handy for close-up portraits or catching distant subjects.
The cameras make their focus adjustments using dual pixel phase-detection autofocus, a subject-tracking autofocus, and a second-generation laser autofocus.
