Dedicated To Photography!

ASUS is committed to promoting mobile photography and enabling ZenFone owners take the best photos. Therefore, all new generation ZenFone 4 family models will feature two rear or front cameras. This is because two cameras and their specialized lenses are ideal for shooting different subjects at different distances.

  • First rear camera – an industry leading Sony IMX362, 12 megapixel main camera with the following technologies:
    • A wide F1.8 aperture that allows more light into the sensor
    • Large 1/2.55” format sensor
    • Large 1.4μm pixels which give the sensor superior light sensitivity
    • Wide aperture and large pixels work together to achieve 5X brighter photos 1 in low light compared to other smartphone cameras.
    • Fast Dual Pixel autofocus system that achieves focus in a mere 0.03 seconds
  • Second rear camera – a flexible, 120-degree field of view 8 megapixel, F2.2 camera with a 200% wider view that is ideal for capturing wide landscapes, large subjects or for shooting in confined spaces.
  • Front camera – the ZenFone 4 also has a higher-than-normal resolution, 8 megapixel front camera for sharp and clear selfies.


Premium glass-metal unibody design

The ASUS ZenFone 4 features a beautiful glass front and back construction sandwiching a finely sandblasted, rounded metal edge. Look at it from the side: it is the very first ASUS smartphone to have a totally flat, beautiful “bumpless” design where the cameras do not protrude out from beneath the protective Corning Gorilla Glass surface
