Asus isn't a big name in phones, but we always appreciate seeing the company's many variations on its phones. Although it didn't announce a new phone for the show, we got a chance to get to know these current handsets. Here, for example, we have the ZenFone 2 (R).
Its 3x optical zoom is what really makes this almost more camera than phone.
A dual-LED front-facing flash is extremely rare on a phone. See more in our hands-on with the Asus ZenFone Selfie.
This variation uses lasers to focus its 13-megapixel camera.
