Dual Rear Cameras
See a bigger and brighter world
ZenFone 4 features an advanced dual-camera system that expands your creative options to take your mobile photography to new heights. Its 12MP main camera is equipped with the industry-leading Sony IMX362 image sensor with large 1.4µm pixels and a wide, F1.8 aperture lens to capture up to 5x brighter and clearer photos in low light. Its 120° wide-angle camera provides a 200% larger view than standard traditional smartphone cameras, letting you fit more scenery and people in the frame for dramatic landscape shots, better group photos, and a more convenient photography experience in confined indoor spaces. With instant switching between cameras, you can quickly achieve the perfect composition for your photo without missing the moment you want to capture. Camera performance is further improved by the Qualcomm Spectra™ 160 image signal processor (ISP), which ensures faster, smoother focusing and zooming, as well as photos with better color accuracy.

Wide-Angle Camera
Fit more scenery and friends in the shot
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.

5x brighter and clearer photos in low light
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.

PixelMaster Technology
Capture reality, fast and steady
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.

Catch the moment with speed and precision
The dual pixel image sensor of ZenFone 4's camera divides each pixel into two phase-detection areas that recognize subject movement by analyzing variations between light rays hitting each area. With 24 million phase-detection areas on the sensor, ZenFone 4's ultrafast phase-detection auto-focus system focuses in just 0.03 seconds, even in low light conditions. The system also tracks subject movement to ensure what's important in your photo is always in focus.

Blur-free photos and steady videos
ZenFone 4's camera has innovative four-axis optical image stabilization (OIS) that allows the lens to move in eight directions to compensate for hand and motion shake, keeping the lens steady to ensure sharp, blur-free photos. OIS also improves camera performance in low-light conditions, letting it use shutter speeds of up to 1/4 seconds — 3x longer that cameras without OIS — for sharper, brighter shots with lower noise. For video shooting, ZenFone 4 employs electronic image stabilization (EIS) that uses smart software algorithms to detect shakes and sharp movement along three axes and automatically apply compensation to ensure smooth and steady videos.

Natural colors, incredible details
Smartphone photos are often marred by unnatural colors, typically caused by artificial lights — so ZenFone 4 has an RGB color correction sensor to capture the scene as you see it. It detects the type of light and automatically applies adjustments to achieve beautiful, natural colors. ZenFone 4 shoots video at up to 4K UHD resolution (3840 x 2160) — 4 times the quality of Full HD — letting you enjoy capturing and sharing your memories with incredible levels of detail.
