The 120° wide-angle camera on ZenFone 4 has a 200%* larger field of view than standard smartphone cameras, so you can fit more scenery and people in the frame for dramatic photos and videos that capture a true sense of place. When taking photos indoors, the wide-angle view makes it much easier to get the shot you want especially in confined spaces where it may not be possible to take a few steps back to fit everyone and everything into the photo. The unique perspective of the wide-angle lens can also be used to stylistic effect, allowing you to exaggerate the sense of space in any setting to capture more dramatic scenes and stunning, expansive landscapes.
* Calculation based on a standard lens with an 83° (25mm) field of view and a wide-angle lens with a 120° (12mm) field of view.
To capture real-world authenticity, ZenFone 4 packs a 12MP main camera with a wide F1.8 aperture, plus the latest Sony® IMX362 sensor with a large 1.4µm pixel size. Combined with optical image stabilization (OIS) that allows blur-free handheld exposures of up to 1/4 seconds 3x longer than cameras without OIS and a six-element lens, 5x* more light can reach the camera sensor, making ZenFone 4 perfect for capturing brighter, clearer true-to-life photos at night, in low-light environments, and in back-lit situations.
* Compared to typical smartphone with 16MP resolution, F1.7 aperture & 1.12µm pixel size.

A dual pixel camera unit with 24 million focus detection sensors two for each of its pixels provides ultrafast 0.03 seconds phase-detection and subject-tracking auto-focus to ensure sharp and clear photos. Together with both optical and electronic image stabilization for blur-free photos and videos, a color correction sensor for true-to-life colors, and true 4K UHD video recording, the camera on ZenFone 4 goes above and beyond other smartphones.

The optional Pro mode offers manual camera controls similar to those found on DSLRs to give you complete creative control over your photography. With one-touch adjustments to shutter speed, white balance, exposure and ISO, as well as the ability to make your subjects stand out with Portrait mode and shoot in RAW format, ZenFone 4s extensive camera controls let you capture stunning images that truly express your photographic vision. In addition to its advanced, manual controls, ZenFone 4s camera has an assortment of fun, creative modes to enhance your photography experience and let you easily achieve professional-looking results.

ZenFone 4s dual camera system is integrated completely within the phone chassis for a perfectly flat rear surface with no protrusions. Both the front and rear of the ZenFone 4 are encased in 2.5D curved Corning® Gorilla® Glass that provides a more comfortable grip and a durable, scratch-resistant finish. A fine, diamond-cut metal edge provides a luxurious accent and micro-etched, concentric-circle detailing that catches the light to make ZenFone 4 shimmer with a rich luster.
