ZenFone 4 is a 5.5-inch smartphone that evolves the ZenFone lineage with luxurious, crafted design and delivers an unparalleled mobile photography experience with a dual-lens camera system featuring the flagship Sony IMX362 image sensor, a large F1.8 aperture lens and a 120° wide-angle lens. The latest powerful and energy-efficient Qualcomm® Snapdragon™ 660/630 Mobile Platform provides performance for every scenario and a high-capacity 3300mAh lithium polymer battery coupled with ASUS BoostMaster fast-charging technology keeps ZenFone 4 going longer.
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 colour accuracy.

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.
High Light Sensitivity
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.
* Compared to typical smartphone with 16MP resolution, F1.7 aperture & 1.12µm pixel size.

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 colour correction sensor for true-to-life colours, 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 colours, incredible details
Smartphone photos are often marred by unnatural colours, typically caused by artificial lights — so ZenFone 4 has an RGB colour correction sensor to capture the scene as you see it. It detects the type of light and automatically applies adjustments to achieve beautiful, natural colours. 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.

PixelMaster Camera Modes
Shoot like a pro, capture the fun
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 4’s extensive camera controls let you capture stunning images that truly express your photographic vision. In addition to its advanced, manual controls, ZenFone 4’s camera has an assortment of fun, creative modes to enhance your photography experience and let you easily achieve professional-looking results.
RAW file support
ZenFone 4 offers the freedom to shoot photos in RAW format, which saves the full data of the photo captured by the camera’s sensor and is ideal for enhancement with editing software. Enhancements possible with RAW files include uncovering fine details in shadows, recovering overexposed highlights, and adjusting exposure with much more latitude than with JPEG files.
Pro mode enables full control over ZenFone 4’s extensive camera settings, including white balance, exposure, focus, ISO, and an impressive range of shutter speeds from 1/10000 to 32 seconds. With the ability to shoot with such long exposures, you can capture gorgeous light trails or stunning night-sky photographs like those traditionally shot with DSLR cameras.
Portrait mode automatically creates a shallow depth-of-field effect ideal for portrait photography that keeps the subject sharp while creating a beautifully blurred background. Previously only possible with DSLR cameras, ZenFone 4 is able to achieve this effect — known as bokeh — with advanced software processing, making it possible to create professional-looking portraits and close-ups with ease.
Modes for creative fun
ZenFone 4 comes with 12 modes for the front and rear cameras that let you enjoy fun and creative effects with ease. Super Resolution mode automatically combines photos to achieve one 48MP photo with stunning detail, GIF Animation and Slow Motion modes add an entertaining twist to shooting movies, Panorama mode lets you capture stunning 270° landscape photos, and Front Camera Livestream mode lets you easily broadcast selfie movies on YouTube Live.
