Available Memory & Storage

The ASUS ZenFone Zoom [Lowest Price] comes with 4 GB of LPDDR3 memory, which is fantastic because it has quite a bit more bloat than the 5.5″ ZenFone 2 Laser (ZE550KL) and the 6″ ZenFone 2 Laser (ZE601KL) we reviewed earlier. Even so, you have at least 2.2 GB of free memory to use – more than what many smartphones (like the honor 5X) come with!

Out of the box, the ZenFone Zoom comes with 128 GB of internal flash storage. Once you deduct about 16.5 GB for the Android 5.0 operating system and 1.1 GB for the ASUS apps, you still have a whooping 111 GB of free space left to use!

That’s more than enough to store 30,000 pictures or 670 minutes of 1080p video. It is unlikely you will find the need to add additional storage space using a microSD card.


Camera Capabilities

The raison d’etre for the ASUS ZenFone Zoom [Lowest Price] is its special 13 MP PixelMaster 2.0 camera, which boasts a 3X optical zoom capability. While optical zoom is not a new capability in smartphones, it is exceedingly rare… especially without a telescopic mechanism.

In this regard, ASUS has achieved an amazing feat – delivering optical zoom capability without a protruding or telescoping lens. The ZenFone Zoom looks, works and feels like a smartphone. And they did this using an ingenious periscopic lens design created by HOYA.

The 10-element periscopic lens arrangement with dual high-precision stepper motors allow the ZenFone Zoom [Lowest Price] to deliver a focal length range of 28 mm to 84 mm. This 3X optical zoom can be further extended digitally for a total zoom length of 12X. This design has some drawbacks though.

Even at its widest, it isn’t very fast with an aperture of just f/2.7. Top smartphones like the Samsung Galaxy Note5 and the Samsung Galaxy S7 edge sport much larger apertures of f/1.9 to f/1.7. When you zoom out all the way to 84 mm, the lens stops down to f/4.8. To compensate for the lower light input, the 13 MP camera is optically-stabilised for up to 4 stops.

Fortunately, ASUS chose to use the Panasonic SmartFSI MN34130 sensor in the ZenFone Zoom [Lowest Price]. Now, this is hardly the best 13 MP sensor they could have used (say, the Sony IMX214 or IMX 258), but it is way better than the dismal Toshiba T4K37 sensor used in the other ZenFone 2 models.

To round up the rear camera’s photographic capability, ASUS also threw in a laser auto-focusing system and a dual-tone LED flash. The laser focusing system is designed to accurately measure distance for close-up photography, while the dual-tone LED flash produces flash photographs with more realistic skin tones.

If you are into selfies though, the ZenFone Zoom only offers a 5 MP sensor with no flash, but the wide-angle lens is fast at f/2.0.

Camera Options

Both the front and rear cameras use a 4:3 ratio for maximum resolution, with small crop sizes available in the settings menu. The main camera can record videos in full 1080p resolution, albeit only with electronic video stabilisation turned off.

The main camera also comes with a bunch of built-in software features like a HDR mode and a low light option that extends the camera’s ability to capture poorly-lit scenes by combining light from multiple pixels. You can also apply some filters or convert your pictures into GIF animation.
