Xiaomi 6, Nubia Z17, Glory 9 and One Plus 5, which were successively released, are domestic flagship with the highest cost performance ratio between 2000 yuan and 3000 yuan. Although this year, under the trend of dual photography, the photography of domestic flagship has gone backwards, which one will be better or worse? Now let's have a look.
PS： Many readers don't understand Love to play computer games Comparison of samples, Why? The magnification is so large. I will explain it here. This is not to limit the amount of hair, nor is it because the camera gap of the mobile phone is too small and requires extreme magnification, but because the horizontal pixels of thumbnails are below 800 on Iooko and third-party platforms. In order to ensure that the effect of viewing the original picture can also be obtained through direct browsing, the magnification is controlled between 200% and 250%. Browse on the official website of Iookie and click the picture to view the large picture. The samples in the large picture are marked with detailed EXIF information to facilitate your research and comparison.
Parameters and description
Among the four mobile phones, the best hardware is Xiaomi 6 with optical anti shake IMX386 and the unit pixel of 1.4 μ m Nubian Z17; One plus 5 has the advantage of high pixels but small unit pixel size, without optical anti shake; For the camera part of Glory 9, there is basically no optical anti shake P10. After root, the model is IMX486 through Glory FM (rumored to be the cost control version of IMX286, and the process is a little backward, resulting in a slightly larger sensor and a slightly poorer quality).
It should be noted that both the focal length and the equivalent focal length are derived from the EXIF information of the sample. The credibility is general: Glory 9 and Xiaomi 6 have the same dual focal length (but it is actually impossible), and the equivalent focal length information of the long focus camera of Glory 9 is obviously artificially set.
What's more special is that the "2x zoom" of Nubia Z17 uses wide-angle IMX318 for truncation output, and the advantage of high pixels is delayed by wide-angle (the wide-angle is larger than the main camera), so the discrimination will not be greatly improved compared with the main camera. Glory 9 is also a truncation output, but the sub pixel is slightly lower, 20 million pixels. The one plus five telephoto sub camera cuts in when the zoom is 1.6 times, and achieves the effect of twice through the truncation output.
Photo experience
Weak light shooting
Extremely weak light shooting (because the screen view angle of Glory 9 is average, the shooting is black, and other machines perform well)
Camera interface and Degree of automation: The camera interface of other mobile phones is very comfortable, except that the Xiaomi 6 camera needs the "Aim" photo option button to call out the panoramic camera and other functions. Except that Xiaomi 6 has no automatic HDR function (Glory 9 does not have this switch, but by default there will be forced HDR processing, and HDR with greater strength is provided in the secondary menu), all machines have automatic HDR and automatic night view functions;
Shutter response and imaging speed: The fastest is one plus five, followed by glory 9, millet 6 is slower, and Nubia Z17 is slower;
HDR and night scene processing speed: One plus five is the fastest. Its multi frame synthesis is carried out in the background, and the experience can rank first among all flagship ships; The HDR speed of Glory 9 is also very fast, but the night scene multi frame synthesis requires about half a second to wait; The HDR and night view of Xiaomi 6 and Z17 require a waiting time of half a second to one second at the front desk, which is average;
Focus: The Z17 uses the IMX362 with full core dual pixel focusing. The focusing speed and success rate are no doubt the first, but extremely weak light also has a certain probability of virtual focus; The second is the one plus five with DCAF dual pixel focusing, and the focus switching speed is also quite fast; Xiaomi 6 and Glory 9 have a certain chance to pull the bellows and out of focus in extremely weak light. Xiaomi 6 performs slightly better. But Xiaomi still has "inability to focus on dim spot scenes ” Problems.
Film rate: After phase focusing solves the problem of out of focus, the biggest enemy of mobile phone photography is actually handshaking. Even from the help of the film rate alone, the author will firmly stand on the side of the optical anti shake scheme. In practice, Xiaomi 6 with optical anti shake also has obvious advantages in multi frame synthesis and weak light film rate. The weak light rate of one plus 5, Z17 and Glory 9 decreases in turn, but they are all 6 millet lower.
Panorama mode, telephoto and HDR characteristics
Glory 9: about 180 degrees of panoramic view, sample 11072 * 3072, 8.56MB;
Xiaomi 6: Panorama is about 200 degrees, sample 14272 * 3712, 14.3MB;
Nubia Z17: the panorama is about 210 degrees, the sample is 14016 * 3328, 11.6MB;
One plus 5: The panoramic view is about 420 degrees, and the sample sheet is 25376 * 3590, 15.2MB.
Detail magnification
The panoramic mode synthesis effect of the four mobile phones is good, and there is no need to wait for a long time. The scene with light stitching trace and large light contrast will not have a light dark intersection line, and the vertical height can reach more than 3000 pixels. PS： The full sample cannot be uploaded because of its large size, so it is compressed with 80% image quality and placed at the end of the article (one plus sample is adjusted to 10000 pixels horizontally due to its high pixel).
Among them, the composite size of Glory 9 is slightly smaller; Xiaomi 6 showed excellent discrimination; Z17 is prone to overexposure; The one plus five composite produced the largest panorama prototype that the author has ever encountered, with a view angle of more than 360 degrees and horizontal pixels of up to 25376, which is not possible for flagship models such as Apple and Samsung. However, it is very easy for the scene to tilt when taking pictures of the ultra long panorama range, which needs to be adjusted by the manufacturer later.
90 degree panoramic contrast
Detail magnification
In addition to the super large panorama, the panorama mode can also be used in nearby tall buildings, where the mobile phone rotates at an angle of about 90 degrees. The four mobile phones all need improvement, but the performance of Glory 9 and One Plus 5 is slightly better in terms of stitching marks, scene distortion correction and discrimination.

One plus five has a high pixel+telephoto lens, Xiaomi 6 has a real double focal lens, Glory 9 and Nubia Z17 are both cut directly from high pixels, and Z17 pixels are high, but unfortunately the sub camera uses an ultra wide-angle lens. The final effect is consistent with the analysis: one plus five is obviously more discriminative, but the ISO is extremely high and the noise is moving. The second is Xiaomi 6, while Glory 9 has strong sharpening. The first impression will be better, but the actual picture details are not as much as Xiaomi 6.

One plus five: HDR mode and HQ mode are not very different, but the dark part is slightly brighter, and the overall effect is natural. In this version of firmware, there is a certain probability that HDR will have a small problem of sample stretching/flattening, while HQ mode will have a local problem of blurring (Pixel XL There are also similar problems), but the HQ mode will have better noise reduction and smearing treatment (but the noise reduction will be reduced under extremely weak light to maintain the discrimination). Daily use can replace the HDR mode and always maintain the HQ mode (all samples below use the HQ mode);
Glory 9: The effect of default mode and manual HDR is not different, and the force is light, but the effect is natural;

Xiaomi 6: HDR will give priority to the dark part brightening, and the effect is more natural than the previous models. However, compared with the competitors of the same generation, there will be problems such as excessive strength, obvious oversaturation of green, etc;

Nubia Z17: The strategy is similar to Xiaomi 6, but the dark part brightens more than Xiaomi. It has good effect in daytime scenes, but the effect is not natural when dealing with light scenes, and the bright part is still overexposed.

In the daytime, scene 2 is magnified in the center (under strong backlight, one plus five appears obvious mirror internal reflection, leading to ghost halo)
Daytime scene 3 central magnification
Facing the strong light source, the glory 9 with the best appearance is the best lens quality (after all, the aperture is small and easy to control). Xiaomi 6, Z17 and One Plus 5 all have a certain degree of reflection/refraction in the lens, and there are problems such as light spots/halos/ghosts, but the overall level is acceptable.

summary
The final result is expected to break many people's expectations:
One plus five: Although the lack of optical anti shake makes it inferior to the previous generation, it limits the upper limit of weak light/extremely weak light scenes and affects the film rate. but The advantages of Yijia's algorithm are still there, A skinny camel is bigger than a horse, plus This year, the photography of the domestic flagship has gone backwards (double photography: blame me), which is the best among the four machines. The speed of focusing, imaging and multi frame synthesis is very fast, and the photography experience is excellent. The white balance and photometry are the most accurate of the four sets, Tolerance, contrast and saturation are well controlled. High pixels do not have much advantage in the daytime. On the contrary, after the light becomes worse, HQ mode is domineering, and the extremely weak light scene can even surpass the IMX362 without optical anti shake;
Xiaomi 6 and Glory 9 will win each other: Xiaomi 6 has the best hardware, but the algorithm still performs poorly. The camera UI design has been backwards, even the photo taking experience is not as good as the previous generation, but the optical anti shake has brought a good film rate. The light measurement is accurate, and the white balance of most scenes is not too biased, but the horizontal contrast, as well as the obvious blue-green trend, shows saturation and contrast above Glory 9; The discriminant force changes in a "U" shape with the change of light, and the maximum discriminant force in the daytime is Glory 9, but the light scene lags behind due to heavy noise reduction and smearing, and the weak light scene can surpass Glory 9 without optical anti shake;
The photo taking experience and white balance of Glory 9 are both good, but the metering is uniformly darker after the light becomes weaker, and the weaker the light is, the darker the metering is. The shooting and actual shooting in extremely weak light are black. But after all, it has no optical anti shake. With an old sensor of the IMX286 level, the aperture is the smallest. It is unexpected that the algorithm can make up for this level;
Nubia Z17: The photography experience is regular, and the white balance is relatively accurate. The light metering is slightly brighter, and the application is quite heavy, resulting in the average performance of details. In order to maintain the film rate, the shutter speed is faster than that of other competitors, and the threshold for multi frame synthesis of night scenes is high. Most scenes are straight out proofs and the opponent's multi frame synthesis PK, which is quite a loss. In addition to the excellent performance of extremely weak light, the potential of IMX362 has not yet been realized. It is a pity that we can only expect the later firmware to be improved.
