  • Conclusion:

    The Asus Zenfone 2 ZE551ML not only has a new built and a refreshed list of specifications over the first-generation Zenfones but it also offers the same high-end performance that one today gets from a premium flagship.


Asus brought its PixelMaster technology on the first-generation Zenfone smartphones that was widely praised by reviewers and users all across the globe. The Zenfone 2 continues the same experience using the same technology and has some additional improvements to deliver even better results.

The Zenfone 2 ZE551ML sports a 13-megapixel camera sensor on the rear along with dual-tone (dual-LED) flash. The camera has an f/2.0 aperture lens and comes equipped with Optical Image Stabilisation (OIS) technology to offer sharper results. In addition, there is a 5-megapixel camera sensor on the front to let users take selfies and their self portraits as well as do video calling using some VoIP services.

Asus has provided a list of features on the software front to enable decent camera performance on the Zenfone 2 ZE551ML. There is a proprietary camera app which has an array of shooting modes such as Night, Panorama and HDR. Furthermore, users can use Beautification, Super Resolution or Low Light to get more from the smartphone’s camera. A special Selfie mode and GIF Animation mode are also available to provide some advance imaging options.

For professionals and serious photographers, the Zenfone 2 ZE551ML has Smart Remove mode and comes along with a Manual mode. The Manual mode particularly has settings for adjusting White Balance, Exposure Value, ISO and Focus. Besides, there is Depth of Field mode to let users create bokeh effect in their frames especially while capturing macro shots.

We tested camera performance of the Zenfone 2 ZE551ML by taking a variety of shots under different environment and some of them are available below for reference. Throughout our testing, we noticed that both the camera sensors of the smartphone are designed to compete against other smartphones in the same segment. Although features such as HDR mode and manual settings are not as impressive as on some high-end smartphones, there is no lag in capturing images under any lighting environment. Color production, noise levels and white balance of the camera sensors under Auto mode also offer a new crisp in each shot.

Apart from capturing still images, the Zenfone 2 ZE551ML is capable of recording videos in up to 1080p (full-HD) resolution. The camera app has video stabilisation to reduce the amount of jerks in final footage and there is Time Lapse mode to capture time-lapse shots at an interval of up to five seconds. In addition, the smartphone provides options to adjust white balance and exposure value while recording videos.

We have not found any issue while recording videos with the Zenfone 2 ZE551ML. Moreover, both the camera sensors deliver impressive video recording results.

Overall, the Asus Zenfone 2 ZE551ML can be considered among the best camera smartphones under mid-range segment. The proprietary features enhance the image results and deliver a professional-like experience to novices.
