ZenFone 4 Pro
ZenFone 4 Pro is the ultimate expression of ASUS smartphone design, crafted to provide luxury in every detail and engineered to deliver an unparalleled mobile photography experience. ZenFone 4 Pro features dual cameras, and is the first smartphone to incorporate three high-end Sony image sensors. The ASUS SuperPixel™ engine ensures the best mobile photography experiences with both the front and rear cameras.
8X-greater light sensitivity in low light
ZenFone 4 Pro has a main camera equipped with the industry-leading Sony IMX362 image sensor with a large 1/2.55-inch size, 1.4µm pixels and a wide, f/1.7 aperture lens to capture brighter and clearer photos in low light. Together with the SuperPixel engine that effectively increases captured light by up to 8X, and OIS that enables blur-free handheld exposures of up to 1/4 seconds, ZenFone 4 Pro captures sharper, brighter and clearer photos at night and in low-light environments.
2X optical zoom, 10X total zoom
ZenFone 4 Pro has fast and responsive camera performance, letting users instantly switch between the dual cameras to achieve the perfect composition without missing the moment they want to capture. A Qualcomm Spectra 180 ISP further improves camera performance, ensuring fast and smooth focusing and zooming, and photos with better color accuracy. The dual cameras on ZenFone 4 Pro also have a 16MP camera with a 2X optical zoom and a 10X total zoom that brings distant subjects closer, putting them in sharp focus while softening background details. Combined with the all-new Portrait mode that uses both the zoom lens and main lens simultaneously to create a shallow-depth-of-field effect, ZenFone 4 Pro’s camera lets users capture gorgeous portraits and close-ups with a sense of depth and a beautifully blurred background for professional-looking photos that rival those from DSLR cameras.
ASUS PixelMaster Technology
ZenFone 4 Pro has an improved ASUS TriTech+™ auto-focus system that incorporates three focusing technologies, including the new Dual Pixel phase-detection auto-focus (PDAF) with 24 million focus detection sensors, second-generation laser auto-focus and subject-tracking auto-focus. TriTech+ automatically chooses the best technology to use depending on the subject, and achieves focus in an amazingly fast 0.03 seconds, ensuring sharp and clear photos. ZenFone 4 Pro also features both optical and electronic image stabilization for blur-free photos and videos, and an RGB color-correction sensor, which automatically detects and adjusts for environmental lighting to ensure photos with beautiful, natural colors. ZenFone 4 Pro shoots video at up to 4K UHD resolution (3840 x 2160) letting users capture and share their memories with incredible levels of detail,
PDAF selfie camera
ZenFone 4 Pro also has an advanced selfie camera, featuring fast, phase-detection auto-focus, a Sony IMX319 image sensor with large, 1.4µm pixels, an f/1.9 aperture lens and the SuperPixel Engine that boosts light sensitivity by 2X while reducing image noise, letting users capture beautifully clear and vivid selfies, day or night, indoors or out.
PixelMaster camera modes
Multiple PixelMaster camera modes enhance the photography experience and let users easily capture amazing photos. For advanced photographers who prefer complete creative control, the camera’s Pro mode offers manual camera controls similar to those found on DSLRs. With one-touch adjustments to shutter speed, white balance, exposure and ISO, as well as the ability to shoot in RAW format and set exposures up to 32 seconds long, users can capture stunning images that express their photographic vision. Slow Motion mode lets users capture fast action scenes at up to 120 frames per second (fps) in 1080p Full HD resolution and then play back it back at a standard frame rate, dramatically slowing action down for a unique video effect. Time Lapse mode enables ZenFone 4 Pro to automatically shoot images at preset intervals and then compiles them into a stop-motion-like video. Unlike other phones, ZenFone 4 Pro can shoot for extended periods by lowering screen brightness and turning off the radios to conserve battery power, resulting in truly breathtaking time-lapse videos.
Powerful and efficient performance
ZenFone 4 Pro is built upon the latest Snapdragon 835 Mobile Platform, which is engineered to deliver powerful performance, ultrafast network connectivity, and a responsive camera experience, while a Qualcomm Adreno™ 540 GPU is designed to provide superior performance for high-end mobile gaming.
ZenFone 4 Pro combines the fantastic energy-efficiency of the Snapdragon 835 Mobile Platform with a high-capacity 3600mAh lithium-polymer battery engineered to deliver up to two weeks of 4G standby time, letting users shoot more photos, stream more videos and music, and enjoy longer gaming sessions. When it’s time to recharge, ASUS BoostMaster technology provides 18W (9V/2A) of power for incredibly fast charging, and built-in safeguards protect against overcharging. Just five minutes of charging provides two hours of 3G talk time, and a 32-minute charge brings the battery to 50% capacity.
Built-in NFC enables convenient mobile payments with Android Pay™, and a front-mounted live fingerprint reader offers improved security and fast phone unlocking in just 0.3 seconds.
