OPPO R9s evaluation: pick a camera phone? Just look at it.

IT168? Evaluation According to Sino's mobile phone sales data in the first half of 216, OPPO ranked second in China market with more than 29 million mobile phones. Among them, the OPPO R9 series, which sold for 88 days and exceeded 7 million, is undoubtedly the core driving force for the sudden emergence of OPPO mobile phones this year. Therefore, as an iterative product, the appearance of OPPO R9s is not only shrouded in aura, but also accompanied by tremendous pressure-not to mention the achievements beyond the predecessors, at least to continue this glory. Therefore, OPPO R9s once again picked up the weapon that OPPO started-the camera phone.

▲OPPO R9s evaluation: a new product that rewrites the ranking of camera phones

Since the release of VOOC flash charging in 214, "charging for 5 minutes and talking for 2 hours" has been the secret weapon of OPPO phones. However, the slogan "The electricity is full, let's talk about taking pictures this time" understates the fact that OPPO R9s will mainly take pictures. OPPO is so confident. Besides how lonely VOOC flash charging technology is in recent years, the 16-megapixel camera adopted by OPPO R9s, which supports F1.7 aperture and launches Sony IMX398 sensor, can really make people feel superior.

"Appearance: leading the industry again

From the first impression of getting started, from the screen size to the body measurements, OPPO R9s still exudes a fresh temperament suitable for young users, but after turning over the back of the fuselage, the author knows that OPPO R9s does not simply continue OPPO R9.

▲ Open the package, hmm, it still smells like that

When I saw the back of OPPO R9s for the first time, I couldn't help wondering where this signal overflowed the antenna. I saw three horizontal lines on the upper and lower parts of the metal shell, which felt like separate staff. As we all know, signal overflow

The antenna is an essential part of the metal-clad mobile phone, otherwise the mobile phone will not be able to talk and surf the Internet normally.

▲ The touch-screen mobile phones are all on the back

The answer is

"

OPPO R9s creatively divides the common signal overflow

antennas into three parts. Because each antenna is only .3mm wide, it is not carefully considered as decorative arts carved on the metal surface by CNC cutting-

"

OPPO calls this" micro-slit antenna ". However, because the normal signal cannot be maintained without the antenna, the industry has been worried about how to hide this thing like "leucorrhea < P >". Before OPPO R9s, it was a very pleasing design to move the antenna to the frame like Apple and Meizu. The arrival of OPPO R9s undoubtedly brings a < P > "creative signal overflow antenna solution.

▲ Speaking of this, the author also turned over the old accounts, and the built-in battery capacity of OPPO Finder (left) OPPO R9s with three-stage design was released first by iPhone 5, which was 169mAh higher than that of R9, reaching 31mAh, but the thickness was .% thinner than that of the latter.

In addition to its slim body,

the body width of only 74.3mm

further improves the grip of

OPPO R9s, even though it is a 5.5-inch quasi-large-screen mobile phone. For reference, the same 5.5-inch iPhone 7 Plus has a body width of 77.9 mm and a weight of 188 grams. In front of

iPhone 7 Plus,

OPPO R9s looks lighter and smaller.

▲ The measured thickness is thinner than the nominal thickness

Besides, OPPO R9s looks thinner than the actual touch. Why? The answer is on the border of OPPO R9s. As can be seen from the figure below, unlike the general arc-shaped frame, the frame of OPPO R9s adds an edge to the arc-shaped transition. Without affecting the feel, there is also a contrast between light and dark on the border. Because the eyeball is very sensitive to light changes, the eyes will unconsciously fall on it. No wonder OPPO officials call this design "condensed light < P >" waistline.

▲ It's a pity that the volume button is a bit empty. I hope that the mass production machine can pay attention to the details here.

OPPO R9s will continue to be equipped with a 16-megapixel front camera, and careful friends should notice it. The position of the front camera of R9s and R9 is just the opposite of that of the sensor group. I don't know if the boss of OPPO forced the designer to be a little different. As a result, the designer reversed the position.

▲ The beauty effect of OPPO R9s is quite excellent, which will be explained in detail later.

You can unlock it by touching the Home button, and you don't need to light up the screen first. The menu key and the back key are still retained, but the function of the former is changed to quickly open the task manager, which is also convenient to use. It is the brightness of these two buttons that is relatively small, which can be seen by the naked eye anyway, but you can't take pictures in a brighter environment.

▲ Touch the Home button, and friends who are used to the physical Home button need to adapt to the unlocking speed experience of OPPO R9s fingerprint

Taking photos: making mobile phone photography more interesting

As the iconic product of OPPO's return to camera phones, the photo experience of OPPO R9s is naturally the key care object of this evaluation. OPPO R9s first adopted a 16-megapixel camera based on Sony IMX398, and supported F1.7 aperture. In this price range of mobile phones, the hardware parameters of OPPO R9s main camera can be called a luxury package.

▲OPPO R9s

makes taking pictures more interesting

But what changes have been brought about by the improvement of parameters? I happen to have an OPPO R9 Plus in my hand, which uses a 16-megapixel camera based on Sony IMX298 and supports F2. aperture. Like R9s, it has a 6P lens structure. From the comparison of the real mobile phones, the

camera of OPPO R9s has a larger aperture. According to the formula, the focal length of the lens is

÷ the lens light passing diameter = the maximum aperture. Since the focal length of OPPO R9s is 4.1 mm and R9 Plus is 3.79 mm, the former light passing diameter is 2.45 mm and the latter is 1.89 mm, and the larger the light passing diameter, the more light will enter.

▲ The camera aperture of OPPO R9s is much larger than that of R9 Plus

"Softer Jiao Wai

Friends who are familiar with taking pictures know that the larger the aperture, the shallower the depth of field, so as to obtain more blurred out-of-focus imaging, which is what we usually call blur.

blur is a common technique in taking pictures, which can not only highlight the subject being photographed, but also produce contrast, three-dimensional sense and so on. Although the aperture of a mobile phone cannot be compared with a professional SLR, the physical laws are still the same.

▲

In fact, many mobile phones are not bad at taking pictures nowadays, so long as users know a little about angles and skills, they can take good photos. OPPO R9 Plus, which supports 2. aperture, has a good blur effect, but OPPO R9s with F1.7 aperture is better than this. At the same distance, R9s has been able to shoot Jiao Wai that feels quite soft.

▲ Jiao Wai of OPPO R9s has been gelatinized

The recent focusing distance of OPPO R9s is 8 cm, and the distance in the test is about 14 cm, which means that if we use macro, we can get photos with better blur effect.

▲ The position of the mobile phone, the position between the theme and the background

Low-light imaging is clearer

In addition to better blur, a large aperture can also bring more light. In addition, due to the 1% increase in the light input of Sony IMX398, the performance of OPPO R9s in low light is further enhanced. The author turned off all the lights in the office and hid in the dim conference room to take a photo of the coffee machine. It can be seen that the photos taken by OPPO R9s are brighter, and the color temperature has been compensated.

▲ Compared with the 1% screenshot in low light environment, you will see more obvious differences. Due to the larger relative light input, OPPO R9s imaging did not appear early, and the color, color temperature, details and sharpness were well preserved. Although OPPO R9 Plus is not full of noise, the lack of light still causes the blur and color cast of the photo.

▲ The details are obviously different in low light

"The focusing speed is faster

In the era of contrast focusing, the focusing speed of mobile phones is very slow. It was not until PDAF phase focusing became popular that the focusing speed of mobile phones was significantly improved. This time, the OPPO R9s using Sony IMX398 brought dual-core focusing to everyone. Prior to this, only the flagship Samsung S7 series and LG G5 supported dual-core focusing technology. We won't say much about the technical white paper here, but let's look directly at the difference between dual-core focusing and PDAF focusing. For the detailed explanation of dual-core focusing, you can poke here

"Real proofs

PS: Due to the upload size limit, individual proofs have been compressed or cut. However, in the lower right corner of the old version, more photo option buttons were moved to the upper right corner, replaced by buttons to rotate the lens. Considering that OPPO R9s is equipped with a 16-megapixel front camera, it is also a consideration to facilitate users to take selfies.

▲R9s (first from the left) and R9 Plus (first from the right)

Let's take some outdoor photos first. The weather has been good recently, and the ones with blue sky and white clouds are very suitable for outdoor photos. However, this kind of large light ratio also easily leads to the problem of picture distortion. For example, the sky is clearly blue, but the photos taken always look like a layer of gray on the computer. Fortunately, there is no such thing as OPPO R9s in my hand. Standing in front of the Guangzhou Station clock, I have a feeling of being bathed in the spring breeze of reform.

HDR mode can only be turned on when it is completely backlit, which looks quite natural. It should be Sony IMX398+F1.7 aperture, which is large enough for the clown to enter the light, and the green leather car in the backlight position can also be accurately exposed.

a photo taken by the roadside, and the F1.7 aperture makes OPPO R9s get a good Jiao Wai blur effect. In addition, the tone processing of imaging is also very pleasing, and the color is full but not exaggerated.

Take another photo from another angle. I feel that the color of the photo from OPPO R9s is very eye-catching and it gives me a sense of pleasure.

OPPO R9s has a little overflow on red reduction in sunlight, which is a bit like Fuji. In fact, red flowers are still quite difficult to handle, or they overflow a little like OPPO R9s and keep a bright feeling as a whole; Either it's a little underexposed, but the picture will darken.

If you see a small partner who clicks on the original image here, you will definitely find that

the details of oppo r9s are 1% enlarged, and there will be some pixelated blur. Simply put, the edge of the subject is not clear enough, and I hope it can be optimized in the next mass production machine.

▲1% screenshot

In the indoor dim light environment, especially in the mall, there are warm dim lights. If the color temperature of the mobile phone is not optimized well, it is easy to have yellow or cold problems. Judging from the proofs, OPPO R9s' control of color temperature is still in place, and the restored scene is very accurate.

Although

there are not many built-in filters in oppo r9s, the results are quite classic. However, I am still not used to this one-by-one interface, and I feel that it is more convenient to change it into the mainstream Jiugongge preview.

▲OPPO R9s filter system

The filter can make ordinary photos instantly get personalized style, so it is very suitable for travel and food shooting. However, using filters too often can create a dependency.
