Asus ZenFone 3 Zoom Navy Black 32GB US Version Unlocked GSM Phone - ZE553KL-S625-3G32G-BK

ZenFone 3 Zoom confines compromise to history. We've combined the industry's best smartphone-camera technologies and innovative dual-lens optics with an outstanding 5000mAh battery and a power-saving Qualcomm® Snapdragon™ S625 processor. The upshot is unparalleled smartphone photography ready to capture every scenario, the moment you need. Catch the Moment — ZenFone 3 Zoom.


  • Dual Rear Lens
    ZenFone 3 Zoom sets the new bar for mobile photography, combining two entirely new camera systems. A 12 megapixel ƒ/1.7 aperture, wide-angle lens with ASUS SuperPixel™ Technology is primed to capture everyday scenes, especially in dark environment; and a 12 megapixel 2.3x optical zoom for high-quality close-ups from farther away. Switching between ZenFone 3 Zoom's dual cameras takes just an instant, and the combination enables an all-new depth-of-field effect — for portraits that look like they were shot by a pro
  • 12x Total Zoom
    ZenFone 3 Zoom's true 2.3x optical zoom lets you shoot super-sharp, close-up photos and videos from right where you stand, and with just a single tap. When you want to feel even closer, use ZenFone 3 Zoom's improved digital-zoom technology to ramp up the magnification to a 12x view — and with clarity that's hard to believe
  • 2.3x Optical-Zoom Camera
    ZenFone 3 Zoom's 2.3x optical-zoom camera and 59mm focal length introduces a whole new way to shoot. 2.3x optical-zoom produce a high quality close-up, and the 59mm focal length lens brought subject closer to you by creating more depth to its background object — so you'll capture depth-of-field effects to rival those achieved by professional DSLR cameras. Combined with the new Portrait mode, the subject stands out more by softly blurring the background. Professionals call this the 'bokeh' effect — but you'll know it as your new way to capture stunning portrait photography
    • * Portrait mode will be available with software update
  • 2.5x Light Sensitivity SuperPixel™ Camera
    To capture real-world authenticity, ZenFone 3 Zoom packs a 12 megapixel camera with a wide ƒ/1.7 aperture and the latest Sony® IMX362 sensor. This combination, along with a large 1.4µm pixel size and a six-element lens, allows 1.25x more light to pass through to the sensor. This is further enhanced by ASUS SuperPixel™ Technology, effectively increasing captured light by up to 2.5x* — making ZenFone 3 Zoom perfect for night time shots and low-light environments. You'll also benefit from both optical and electronic image stabilization (OIS and EIS) technologies for blur-free shots and video every time, a RGB color-correction sensor for true-color photography, and true 4K UHD video recording
  • ASUS SuperPixel™ Technology
    ZenFone 3 Zoom's ƒ/1.7 aperture is one of the largest found on any smartphone camera, and it's coupled with a 1.4µm pixel size (1/2.55" sensor size) that's also among the largest in the industry. The aperture of any camera is the hole behind the lens through which light passes to reach the sensor. The larger it is, the more light is able to reach the sensor, and the better the camera will be for night shot, low light and back light photography. Combining with ASUS SuperPixel™ Technology with the SuperPixel™ Engine that drives its software enhancement to further increases its low light performance by intelligently controlling ISO levels while shooting and noise reduction in post-shot processing. ZenFone 3 Zoom can captures up to 2.5x more light in any given circumstance compared to competing smartphones. So, ZenFone 3 Zoom is a star performer in all conditions — and cuts through the dark even when the light is low
  • ASUS TriTech+™ Technology
    We've upgraded ZenFone 3 Zoom with ASUS TriTech+™ Technology, adding an all-new Dual Pixel PDAF (Phase Detection Auto Focus) system that uses similar technology found in DSLR cameras. Every single pixel on the Dual-Pixel sensor is used for phase detection, enabling auto-focus that's so incredibly fast, actually the world's fastest and seamless that even the most sudden movements are caught in the act — even when the light starts to fade. TriTech+™ also features Subject-Tracking Auto-Focus for both photos and videos to keep the object in clear focus, and Laser Auto-Focus for variable distance and lighting clarity in just 0.03 seconds
  • RGB Color Correction Sensor & 4K Video
    Smartphone photos are marred by unnatural colors, typically caused by artificial lights — so ZenFone 3 Zoom has a RGB color correction sensor to capture the true scene. It detects the type of light and automatically applies the best settings to achieve the perfect balance for natural looking colors. ZenFone 3 Zoom shoots video at up to 4K UHD resolution (3840 x 2160) — or 4 times the quality of Full HD! There's nothing complicated for you to do: just point, shoot and share your memories, all captured with incredible levels of detail
  • Selfie Camera
    ZenFone 3 Zoom has the world's most advanced dual-lens smartphone-camera system — and it's also a selfie superstar. The remarkable front-facing camera employs a 13 megapixel Sony IMX214 sensor for high-resolution selfies, and the ASUS SuperPixel™ Technology can further enhanced the light sensitivity up to 2 times. Screen Flash feature turns the entire screen bright white for brilliant illumination in low-light environments. Combined with the ZenUI Camera app's unique Beautification and 140° Selfie Panorama modes, you'll shoot selfies with more detail than ever before, add instant glamor and ensure that every friend is in the frame
  • Manual Mode
    ZenFone 3 Zoom's Manual mode puts pro-level creative controls right in front you, for a DSLR-like experience that fits in a pocket. These include one-touch control over shutter speed, white balance, EV, ISO and metering, plus two features unique in the ZenFone range to ZenFone 3 Zoom: support for the professional RAW photo format, and the ability to switch instantly between the dual lenses for either 25mm or 59mm focal length. Shoot wide or close, and store every original detail — pro photography has never seen so simple
    • * RAW support will be available with Android 7.0 (Nougat)
  • Battery
    ZenFone 3 Zoom's incredible cameras will encourage you to take more photos, more often — and that's why we've fitted a high-capacity 5000mAh battery, it can even charge attached devices as a power bank. With this vast power resource hidden within ZenFone 3 Zoom's slim 5.5-inch frame, you'll simply stop worrying about battery life. Enjoy the reassurance of up to 42 days standby time, and shoot all day, every day — as often as you like. And you won't stop at photos: with so much energy in store, record videos in glorious 4K UHD quality for as long as you need; or set ZenFone 3 Zoom's Time Lapse mode to create transition sequences that capture all day and through the night. ZenFone 3 Zoom is even able to turn power bank, meaning you can use its seemingly endless energy to charge your other devices
