ASUS recently announced two new smartphones: the ZenFone AR and ZenFone 3 Zoom. Each phone has an array of cameras that provide advanced imaging features such as simulated depth of field and augmented reality (AR).

The ZenFone AR is the first smartphone that supports both Google’s Tango AR technology and Daydream VR. Tango, which has been in development for some time and recently debuted in Lenovo’s Phab 2 Pro, gives the ZenFone AR motion tracking, depth perception, and environment mapping capabilities, allowing you to do things like measure physical objects, play new interactive games, or view maps and other relevant data overlaid on the environment shown on the phone’s 5.7-inch QHD SAMOLED screen.

The phone’s AR and imaging experiences are enabled by ASUS’ TriCam system that combines a motion tracking camera, a depth camera that’s paired with an infrared illuminator, and a 23MP Sony IMX318 Exmor RS primary camera paired with an f/2.0 lens. It also has 4-axis OIS to help steady the camera during long exposures, a color spectrum sensor to improve white balance accuracy, and a hybrid autofocus system that combines dual-pixel phase detection (2PDAF), laser, and contrast based AF that should provide good performance in a range of lighting conditions. ASUS claims the camera can focus in as little as 0.03 seconds in ideal conditions. The front camera uses an 8MP sensor and includes its own LED selfie flash.

Inside the ZenFone AR is a Snapdragon 821 SoC that includes two of Qualcomm’s custom Kryo CPU cores running at up to 2.35GHz and another two Kryo cores that can reach 2.19GHz. The Hexagon DSP provides the six degree of freedom position tracking used by Tango. Because of the high demands placed on all the processors inside the SoC (CPU, GPU, DSP, ISP) when running AR and VR applications, the ZenFone AR includes a heat pipe to help keep things cool. It will be interesting to see how this cooling solution works and if it proves sufficient to keep the SoC from throttling during heavy use.

The SoC is paired with either 6GB or 8GB of RAM. There’s also several internal storage tiers starting at 32GB and ranging all the way up to 256GB, with the option to expand storage further with a microSD card. It only comes with a 3300mAh battery, however, which seems a bit small for a 5.7-inch phone that’s intended to run power-hungry VR/AR applications.

The aluminum frame has chamfered edges around the front and back. A power button and volume rocker are on the right edge, while the USB Type-C port, 3.5mm headphone jack, and single downward-firing speaker are all located on the bottom edge. The back is covered in charcoal-colored leather, with the serious-looking camera module with a stainless steel surround being the dominant feature. The front is covered edge-to-edge with Gorilla Glass 4. The pill-shaped home button doubles as a capacitive fingerprint sensor and is flanked by capacitive back and recent apps buttons.

The ZenFone 3 Zoom does not support Tango or Daydream. Instead it focuses exclusively on photography. It uses two rear cameras with different focal lengths to provide what ASUS calls 2.3x optical zoom. This does not work like a true zoom lens, however, which can smoothly adjust focal length between its extreme settings. The ZenFone 3 Zoom simply switches between the two cameras in addition to performing digital zoom.

The wide angle camera has a 25mm equivalent focal length that captures a wider field of view but makes objects appear smaller and farther away than they appear to the naked eye. The zoom camera has a 59mm equivalent focal length that makes objects appear slightly larger and closer relative to what your eye sees but has a more restricted field of view. Having a second camera without a wide angle lens is actually very useful in many situations. This approach is similar to what Apple used for the iPhone 7 Plus’ dual camera system.

The wide angle camera uses a 12MP Sony IMX362 Exmor RS sensor with large 1.4µm pixels. It has a six element lens with a large f/1.7 aperture that lets more light reach the sensor, boosting low-light image quality. It also includes OIS and a color spectrum sensor like the ZenFone AR, along with the same hybrid autofocus system that combines dual-pixel phase detection (2PDAF), laser, and contrast based AF. The zoom camera, which has a five element lens array, also uses a 12MP sensor; however, ASUS didn’t provide any further details, so it’s not clear if it also has OIS and the same hybrid AF system. There’s also a 13MP selfie camera that uses the screen for a flash.

The ZenFone 3 Zoom makes due with a Qualcomm Snapdragon 625 SoC that has an octa-core Cortex-A53 CPU running at up to 2.0GHz. It also has half the amount of RAM as the ZenFone AR, with 3GB or 4GB options available. You can also choose between 32GB, 64GB, or 128GB of internal storage that’s expandable via microSD.

Besides the dual rear camera, the ZenFone 3 Zoom’s other standout feature is its large 5000mAh battery, which, when combined with the Snapdragon 625 and its A53 CPU cores on the 14nm LPP FinFET node, should deliver excellent battery life.

The aluminum uni-body chassis is available in three different colors: Glacier Silver, Navy Black, and Rose Gold. The sides and corners are nicely rounded, similar to the iPhone 7. There’s a color-matching capacitive fingerprint scanner on the back and capacitive navigation buttons on the front below the screen. Gorilla Glass 5 covers the 5.5-inch 1080p SAMOLED display, which ASUS claims reaches a peak brightness of 500 nits.

The ZenFone 3 Zoom will be available in February, while the ZenFone AR will be available in Q2 2017.

    After my awful experience with the Zenfone 2 I don't think I'll buy an Asus phone ever again, no matter the specs.
  • MananDedhia - Friday, January 6, 2017 - link

    I had the same experience with the Zenfone2. Went absolutely wonky after a year. Unless the build quality and user experience improves, its a firm no to ASUS.
  • MonkeyPaw - Friday, January 6, 2017 - link

    Care to elaborate? ZP2 used an Intel Atom chip, and I wasn't really that impressed with it on Android (I tried a ZenPad 8). These use QC SOCs, so maybe that will make for a better experience.
  • baka_toroi - Saturday, January 7, 2017 - link

    Asus is not a company anybody can trust.

    The main reason I won't buy an Asus phone again is the hardware issues. Zenfone 2 was swarmed with random problems, ghost touches being the most awful. It would randomly become unusable for whole minutes. This is a systemic problem a lot of people had, it wasn't just about a bad unit I got.

    Then there's the software side. Granted, Intel dropped support for x86 Android but they did support it up to 5.1 and Asus never updated it's 5.0 OS to 5.1. Their lack of communication was outstanding and when they did promise a timeframe they failed on it, not even apologizing about it or saying what problems they had or what was the actual development status.

    Maybe they sorted it all out? They might've improved on hardware quality but software wise they're irredeemable broken.

    It's a nasty world in tech when even Intel can instantly kill an entire product lineup, like what it did to Atom. That meant Zenfone owners were stuck with a dead platform with no way out except to buy new devices.

    Actually that's how it is with Android as a while. Qualcomm may show better support than bottom feeders like Mediatek but once they stop writing closed source drivers for a new Android release, you're out of luck.

    I have the exact opposite experience with a ZP2 Deluxe: I bought it for less than 250 euros, and it works very well. Sure, it originally has Android 5.1 and Asus took much time to release the upgrade to 6.0.1, and I don't know if it will ever receive 7.x, but hey - this is the norm on Android world. The only complain I have is screen brightness, which should be better managed: it is too bright in dark condition, and too dark under sunlight.

    WOW! I've had the Zenfone 3, the 5.2 inches and I've already pre-ordered the Zenfone 3 zoom since all I've had is an incredible experience with the Asus Zenfone! For day 1 eveything has gone well with no problems at all, random upgrades even though I haven't had any problems and just yesterday I got an update for it for Android 7. Can't wait for the Zenfone 3 Zoom! Sorry about your problems, they sound like mine with the LG G4 overheating, rebooting until finally they refunded my money this was the phone i got before the zenphone.
  • drajitshnew - Friday, January 6, 2017 - link

    Please elaborate
  • negusp - Friday, January 6, 2017 - link

    I assume they didn't wipe the cache or do any sort of decent cleaning, and the phone inevitably slowed to a crawl, especially under the Zen UI.
  • WJMazepas - Friday, January 6, 2017 - link

    I did have a Zenfone 2 but it got so buggy that i had to change my phone.
    The camera stopped working, the phone crashed when i got a notification on the lock screen and it had a lot of other minor issues
