Asus Zenfone 5 – See what Pixelmaster can do

One of the most regarded feature on a smartphone is the camera. Some even trying to do something unusual like put 2 module on 1 side. No, i’m not pointing at particular smartphone model 😛 And this time, let’s take a look on how the Zenfone 5 fares againts the competition with its 8 Megapixel camera.

So, this is the continuation of my previous review, in case you missed it, it’s here. 😀 The Zenfone 5 is equipped with 8 Megapixel camera. As for the others, Zenfone 4 has 5 MP and Zenfone 6 has the biggest with 13 MP. That being said, all of the Zenfone was powered by Asus’s Pixelmaster technology to improve the overall image quality.

But eventually as not all the Zenfone was build equally with the same feature, some of the Pixelmaster technology was not included in the little brother, Zenfone 4. It’s the Low-light Mode. It’s only available on the Zenfone 5 and 6. What’s so special about this Mode? Let’s take on a little technical course.

Using Sony and Panasonic BSI sensor for Zenfone 5 and 6, these two can capture better low light with some special algorithm. By combining or binding 4 pixel information into 1 pixel the low light mode can pick up more light up to 4x. This is why Asus claims in low light mode, it can capture up to 400% light sensitivity in addition with 200% more contrast. But there’s a downside with these Low Light Mode that is the output resolution is far lower than the original sensor resolution. For Zenfone 5 it’s 2 MP and Zenfone 6 it’s 3MP. The lower pixel count is because of the algorithm employed by the Low Light Mode.

Here’s a sample on how Low Light Mode can “see” what the others can’t. I’ve taken 3 sample, one Auto, one Night Mode, and the last one is Low Light Mode. (click to see full size)

As you can see, it’s indeed increase the whole light sensitivity, but the result is just more for “better than no picture” side. Just click on the picture to see the full size.

For general situation, or even there’s a lot of light, say in the broad daylight, the Zenfone really capture a nice picture. It’s crisp, with a good color rendering.

Another sample below is a macro shot on a daylight an the other one is at night with Low Light Mode. (click to see full size)







The Zenfone also offer a lot of modes in camera menu to enhanced the user experience.


Overall, Zenfone 5 camera i’m using here really can output nice picture. And considering its price, i can say actually it has more bang for the buck in the camera department against the other smartphone in this class.
