The Oppo R9s is surely a well-designed smartphone from Oppo. What brought to our attention is the amount of attention Oppo puts into marketing the Oppo R9s camera. It is really that good? Techslack puts it to the test.

The Sony Exmor IMX398


The Oppo R9s features a special customized camera sensor from Sony, the 16MP IMX398 Exmor RS Stacked sensor. The sensor is a collaboration between Oppo and Sony, offers supreme performance over other mainstream cameras. Exmor RS is an advance line of CMOS image sensor develop by Sony.

This line of sensors is the first to use stacked back-illuminated mobile sensor, allowing razor sharp image capturing. Such technology enables HDR (High Dynamic Range) capturing not only in the picture but also video, which the end result of image or video with a great balance of exposure and shadow. Producing a well-lighted image in an almost impossible situation like hush sunlight or low light area is well capable via the Oppo R9s.

DPAF Custom Dual Core Auto Focus

Auto Focus is something we all love and hate, the ability to make a subject stands out from the background is one of the keys for a good photo. When we usually tap the phone screen to select the area we’re trying to focus it is simple, but in a low light area it tends to become a hard task to archive.

The DPAF is a technology that is developed for these specific situations. It is a technology designed to give a smooth, fast subject tracking and fast autofocus acquisition when shooting still photos.

To test this out, we invited Milky the cat to put it the test!


F1.7 Aperture

One of the way of producing a well-lighted picture is by allowing enough light to enter the sensor and the element that guards this factor and a mechanism called “Aperture”. Think of this as your window; the wider the window can be opened, the more light can enter. The brighter the image can be as an end result. Normally, the smaller F number (Aperture) gets, the wider the windows it is. So with F1.7, The Oppo R9s actually offers the best in class in terms of Aperture size, with other smartphones unable to offer such in similar price range.

Also, the larger the aperture is, the more likely that the camera can recreate Bokeh effects. Bokeh is that blurring effect at the background out of focus.This is a highly sought after effects by professional photographers. By offering F1.7, Oppo R9s almost guaranty this as a gear that won’t fail to impress shutterbugs.

In this test, we invited Tommy the cat to help us out. Notice as we focus on the bell, the surrounding of the cat were in a state of blurriness. This is Great bokeh if you ask me! and Tommy will agree too!

16MP front Camera

R9s front camera

Since the Oppo R9s packs a mean main shooter, it does not mean Oppo go easy on the selfie camera. Enter the 16MP selfie camera, few of the flagship smartphone carries a selfie with such megapixel, and we’re quite impressed with how it works out.

The selfie camera has an F2.0 aperture, and with a 1/3-inch sensor. A similar smartphone that used a similar camera like this is the 2014 iPhone 6, but only at half of the megapixel counts, and we all remember the glorious camera result that is presented by an iPhone. Does this mean Oppo R9s selfie camera is as good as iPhone 6? We don’t have an iPhone 6 laying around so we let you be the judge.


Advanced noise reduction algorithms

One of the biggest challenges with cameras is to capture images at low light environment. How camera usually perform when dealing in low light situation is by cranking up the ISO. This will increase the sensitivity of the sensor, but create static noise within the image. So the key is to try to crank the ISO high enough to ensure good exposure, but not so high to cause too much noise.

How Oppo deal with this is to use Advance noise reduction algorithms to eliminate noise in the image. See this as a Photoshop built into Oppo R9s, dealing with noise every time you take pictures automatically.

But just to put more weight to this, it is not necessary that the result is good, sometimes this does remove details away from the image, TechSlack put this to test to show us how much detail is taken away during this process.
