Last month ASUS announced the latest iteration of the ZenFone series, the ASUS ZenFone 4 and the ASUS ZenFone 4 Pro, marking an exciting advancement in mobile photography. The ASUS ZenFone 4 Pro features the Qualcomm Snapdragon 835 Mobile Platform, and the ASUS ZenFone 4 comes with one of the two new 600-tier platforms, the Snapdragon 660 Mobile Platform and Snapdragon 630 Mobile Platform.
All three smartphones boast next-generation camera technologies, such as innovative dual-camera systems, Sony image sensors, and optical image stabilization, that don’t sacrifice power or performance, thanks to Qualcomm Technologies.
ASUS ZenFone 4 Pro
The ASUS ZenFone 4 Pro is a luxury phone loaded with a variety of tools for photographers in every setting, all powered by the Snapdragon 835.
The phone’s main 12MP camera features the Sony IMX362 image sensor, with a large 1/2.55-inch, 1.4µm pixel, F1.7 aperture lens. A 16MP second camera, a Sony IMX351 sensor, features a 120-degree wide-angle lens, as well as a 2X optical zoom for up to 10X total zoom. Portrait mode uses both lenses simultaneously to take striking portraits and close-ups capable of smooth bokeh-effect backgrounds. Together with the ASUS SuperPixel Engine, designed to increase captured light by up to 8X, and image stabilization, photogs can snap bright, clear photos at night and in low light.
The dual-camera system uses ASUS’s TriTech+ tool, which combines three focusing technologies: infrared lasers, traditional continuous autofocus, and phase detection auto focus, or PDAF, which is traditionally only found in DSLRs. TriTech+ is engineered to assess and use the best of these technologies automatically, depending on your photography subject, all in under nearly 0.03 seconds.
The cameras also include an assortment of PixelMaster camera modes that allow you to adjust settings. Mobile photographers can control the shutter speed, white balance, exposure, and ISO with a single touch. On the flipside, the ZenFone 4 Pro’s 8MP front-facing second camera is designed to boost light sensitivity, giving selfie snappers the same responsive auto detection for beautiful photos, day or night.
With this dual-camera system, you can also record 4K UHD resolution video. The three-axis Electronic Image Stabilization (EIS) software can detect and compensate for shaking during recording, resulting in smooth and stunningly vivid videos. Slow Motion mode supports video at up to 120 frames per second in 1080 Full HD, while the Time Lapse mode saves power by turning off the display and radios while recording, so you have more options to experiment, capture, and create your blockbusters.
The ZenFone 4 Pro’s innovative camera capabilities are boosted by the efficiency and power provided by the Snapdragon 835 mobile platform. Its impressive 3600mAh battery is engineered to provide up to two weeks of 4G standby time. The ASUS BoostMaster technology can provide 18W (9V/2A) of recharging power, and safeguards against overcharging. Just five minutes of charging can replenish two hours of 3G talk time, and 32 minutes can bring the ZenFone 4 Pro battery up to 50 percent.
The phone’s stereo speakers come with Hi-Res Audio certification, designating support for 24-bit/192kHz audio playback with low-distortion sounds, even at high volumes. Three noise cancelling microphones can remove unwanted environmental sounds for impressive call quality and audio recording clarity. A new AudioWizard app lets you tailor headphone audio to your liking for DTS Headphone:X theater quality 7.1 channel sound, while a combination of both Bluetooth 5.0 and Qualcomm aptX Low Latency tech is designed to deliver an enhanced wireless headphone experience.
Display and design
The 5.5-inch AMOLED display supports full HD resolution. Whether you’re in a sunny outdoor space or shooting in a dark room, the ASUS Splendid display technology can adjust to the screen’s color temperature based on the environment, making it easy to watch, share, and browse virtually anywhere.
The ZenFone 4 Pro continues the ZenFone’s legacy of sleek design, with its solid aluminum unibody, crafted by nano molding technology for a light-yet-strong frame. Its dual-camera setup is completely integrated within the phone chassis for a smooth look, allowing it to lay completely flat. Both the front and rear of the device is encased in 2.5D curved Corning Gorilla Glass, designed to be scratch-resistant and durable.
ASUS ZenFone 4
There are two choices available for the ASUS ZenFone 4: one powered by the Snapdragon 660 mobile platform and another by the Snapdragon 630. Both are engineered to provide innovative dual-camera photography hardware, tools, and efficient battery performance, while supporting download speeds of up to 600 Mbps (LTE Cat 12) and upload speeds of 150 Mbps (LTE Cat 13) for superior, fast connectivity.
The ZenFone 4’s main 12MP camera is equipped with the Sony IMX362 image sensor, designed with a 1/2.55-inch size, 1.4µm pixels f/1.8 aperture lens, so you can capture photos that are up to 5X clearer and brighter in low light. The second camera is equipped with a 120-degree wide-angle lens, giving photographers a 200-percent wider view than standard smartphone cameras. Combined with optical image stabilization (OIS), the ZenFone 4 allows blur-free handheld exposures of 0.25 seconds, allowing up to 5X more light to reach the camera sensor. This allows you to take crisp, clear images in a variety of low-light environments.
Mobile photographers can shoot videos at up to 4K UHD (3840 x 2160) with 12 PixelMaster camera modes, which is, essentially, the same as standard DSLR cameras. The three-axis Electronic Image Stabilization (EIS) software compensates for shakes during recording, creating smooth, vivid videos. Slow Motion mode supports capture at 120 frames per second in 1080 Full HD, while the Time Lapse mode is designed to optimize battery use by turning off the display while recording, all in RAW file formats.
The ZenFone 4 has Hi-Res audio certification stereo speakers, indicating support for 24-bit/192kHz audio playback with low-distortion sounds, even at high volumes. Three noise cancelling microphones are designed to remove unwanted environmental sounds for audio recording and superior call clarity. The smartphone has a new AudioQizard app that lets you tailor your headphone audio for DTS Headphone:X theater quality 7.1 channel sound, as well as Bluetooth 5.0 and Qualcomm aptX Low Latency technology, perfect for wireless headphone users.
Performance and power
The ZenFone 4 with Snapdragon 660 powers up to 6GB of RAM with the Qualcomm Kryo 260 CPU and the Qualcomm Adreno 512 GPU, which offers a powerful 3D mobile game experience and battery efficiency. Its eight CPU cores utilize two clusters, one for demanding performance and the other for power efficiency. This helps to reduce the impact on battery life while you take photos and stream video.
The Snapdragon 630 based ZenFone 4 powers up to 6GB of RAM and features the Adreno 508 GPU. The Snapdragon 630 is designed to deliver 30 percent faster graphics performance than the previous generation, while continuing to power its innovative camera features and 3D gaming options.
Both the Snapdragon 660 and Snapdragon 630 use 14nm FinFET processors. Combined with the 3300mAh high capacity battery, the ZenFone 4 is designed for up to 23 days of 4G standby time. ASUS Bootmaster tech can provide 15W of power for two hours of 3G talk time with a five-minute charge, or 50 percent battery capacity with just 36 minutes of charging.
The ZenFone 4 has an expansive 5.5-inch Super ISP+ display encased in durable 2.5D-curved Corning Gorilla Glass. Both models are available in three gorgeous colors: Midnight Black, Moonlight White, and Mint Green.
