Asus ZenFone Zoom pure black


At $399 (which is around £275 or AU$560), the Zoom isn't cheap -- you're paying the early adopter tax to get your hands on it. If you're looking at alternative phones with great cameras, then your best bet would still be flagships such as the Samsung...

Asus' ZenFone Zoom breaks new ground with a built-in optical zoom camera that doesn't stick out or appear to move. Photos taken are generally great, but worse in low light.

The phone software peppers you with ads by default. Camera performance feels sluggish.

The Asus ZenFone Zoom puts cool new camera tech to work, but its bloated software and poor overall performance keep it from being a phone you'd want to buy.

Asus ZenFone Zoom (Unlocked)


The Asus ZenFone Zoom is a camera-centric unlocked phone with a 3x optical zoom lens, but it's held back by average sensor quality, a slow camera app, and a lack of 4K video recording.

3x optical zoom. Manual camera controls. Premium build.

Sluggish camera app. No 4K video. Unimpressive battery life. Dated UI with heavy skin and lots of bloatware.

Software and Conclusions The Zoom ships with Android 5.0 Lollipop , which is starting to feel a bit long in the tooth now that Android 6.0 Marshmallow is showing up on more devices . Asus has confirmed that the ZenFone 2 line will get Marshmallow....

Asus ZenFone Zoom review


Do you need a zoom lens on your phone? For years, consumers have been more than satisfied with the default focal length of iPhones and Android handsets. It's a wide — but not too wide — view that...

Premium look and feel ; microSD card support ; Great dedicated shutter button

The camera itself is lacking ; Too many useless apps ; Average battery life

Asus Zenfone Zoom Review


Asus has found its niche in the mid-range segment, as opposed to trying to duke it out with the elites in the high-end space. From the looks of it, though, it's working out for the company, at least for the most part. Its Asus ZenFone 2, for instance,...

3x optical zoom gets us closer to a shot ; Rich set of shooting modes & controls ; Relatively slim profile ; Premium design ; Fast recharge time ; Snappy processing performance ; Not terribly expensive at $399

No major improvements to image quality ; No 4K UHD video recording option ; Video stabilization is limited to 720p mode ; Lack of continuous auto-focus ; Extremely cold screen color temperature ; Washed out looking screen

Asus established itself as a formidable competitor in the mid-range segment with the introduction and release of its ZenFone 2 last year. Since that time, they've diversified its ZenFone line with an assortment of variants – including this latest one...

Asus ZenFone Zoom Review: The smartphone camera to beat?


Asus built this phone around one specific photography feature. Is it the phone camera to beat? Here's our full ZenFone Zoom review!

Practical build quality with premium materials ; Camera-centric ergonomics ; Innovative camera zoom design

Lackluster photo and video output ; Mediocre battery life for multimedia and content creation ; Large footprint for medium sized screen

This is always painful. We want to reward daring design. We want to celebrate when companies take risks. The ZenFone Zoom is an incredible feat of camera design, but the crown jewel feature of this phone in many ways compromises the camera that the...

Asus ZenFone Zoom Review: Optical Zoom Impresses


Under the right circumstances, the ZenFone Zoom really shines, with an impressive optical zoom and dedicated camera buttons that I wish more phone makers would emulate. But the phone's lackluster image processing can make that optical zoom feel more...

Rear camera has 3x optical zoom ; Dedicated camera controls ; Built-in manual photo mode ; Removable leather back ; 4GB of RAM and 64GB of storage come standard

White balance issues with camera ; Subpar battery life ; Mediocre audio ; Clunky interface

This Android phone's 3x optical zoom is a powerful feature for mobile photographers, but its battery life and bloatware are turnoffs.

Asus ZenFone Zoom


Hands-on: Asus packs optical zoom in its new smartphone

All told, we’re really looking forward to giving the ZenFone Zoom a proper test run closer to its release date later this year. If that camera holds up it could be a real contender especially as Asus is planning to charge only $399 for it.

Asus ZenFone Zoom eyes-on: The phone with 3x optical zoom - Pocket-lint


Asus has shown off a new smartphone called the ZenFone Zoom. The company didn't give the media a chance to touch and hold the ZenFone Zoom on the show

Asus ZenFone Zoom review


What's a ZenFone 2 with a better camera worth to you?

Slick design ; Thoughtful button placement ; Some neat ZenUI features ; Slight reduction of photo noise

Squishy button action ; Questionable value ; Subpar screen ; ZenUI hurts more than helps ; Camera doesn't rock the boat

Asus adds svelte styling and a 3x optical zoom snapper to the ZenFone 2. While the new traits are welcomed, neither makes a convincing enough argument to make this your next phone.

Innovative camera, iffy performance: Our ZenFone Zoom review


The Asus ZenFone Zoom is the first phone with an optical zoom lens that doesn't protrude out of the phone, a mighty impressive accomplishment. But don't start tossing money at Asus just yet. The phone's spammy software and slow camera drag it down too...
