Taiwanese manufacturer Asus is a pioneer in the area of smartphone zoom, and so it does not come as a surprise that its latest flagship model, the ZenFone 4 Pro, comes with a quite impressive looking dual-camera setup that offers 2x zoom capability.

The main sensor in the dual-camera is a 12MP 1/2.55" Sony IMX362 that comes with large 1.4um pixels and sees the world through a fast F1.7 aperture and 4-axis optical image stabilization. In terms of autofocus, Asus bundles PDAF with laser-based time-of-flight technology for reliable performance in all light conditions.

The main camera also comes with a manual mode that allows for up to 32 second shutter speeds, and 120 fps slow-motion video at 1080p resolution in addition to a 4K mode. Finally, a super-resolution mode can create 48MP images out of four 12MP captures.

The secondary camera uses a smaller Sony IMX351 sensor with 1um pixels and a slower F2.6 aperture. The camera offers both 2x optical zoom and a background-blurring bokeh-effect, but the smaller sensor and a lack of OIS and PDAF in the tele-module probably means those modes are best reserved for bright-light shooting.

In the front camera you'll find an 8MP Sony chip with 1.4um pixels and an F1.9 aperture, alongside other flagship-worthy specifications: the Android OS is powered by a Snapdragon 835 chipset, images can be viewed on a 5.5" 1080p AMOLED display, and the phone is wrapped up in a glass-metal-glass sandwich design body.

Prices for the ZenFone 4 Pro start at $600.
