The change of one plus five cameras is normal in the eyes of the same generation - adding dual cameras at the expense of optical anti shake, but sticking to the 16 million high pixel scheme when peers "degenerate" to the 12 million pixel scheme is the choice of manufacturers when designing. But compared with the old ISP, the old sensor, the smaller aperture, but the optical anti shake one plus 3T, Can one plus five, which increases the light intake by 34%, offset the impact of the lack of optical anti shake? This is the main question of this comparison:

The framework of this article is derived from the detailed review of one plus five, and the double photographing and blurring parts have been removed. All the samples that could not be added due to space limitations before were released. Detailed comments can be viewed Detailed Evaluation of One Plus Five The S8 and iPhone are used as standard samples here, representing the peak and the top reference line respectively, and the Nubia Z17 without optical anti shake IMX362 will be added later as a reference.

In terms of photography experience, In addition to the fact that the dim light shooting is slightly worse than the previous generation, the shutter response, imaging speed, HDR/HQ and night scene algorithm processing speed of one plus five have improved to a certain extent, and there is no small regret that the shutter needs to wait after consecutive shooting in the previous HQ mode, which is the first echelon of the active photography experience. The contrast, saturation, and definition of the picture when shooting should be better than one plus 3T, which can easily give people the illusion of better photography.

However, one plus five has no optical anti shake, and the yield of weak light and HQ mode has obvious regression. IMX398 has made some progress in the weak light scene compared with the enhanced focusing function of 298. Although there is still a gap between the weak light focusing and the full pixel dual core focusing S8, the iPhone has been taken lightly.

Telephoto

Parameter description: The one plus five telephoto lens, like the iPhone, cannot be triggered when the light is weak. But the special thing is that its long focus sub camera is cut in at 1.6 times zoom; After being blocked, it will also try to switch back to telephoto from time to time; After the sub camera is cut in, the sample output is 20 million pixels no matter how high the zoom factor is.

The size of the two camera sensors of one plus five is 1/2.8 inch. The software shows that the focal lengths are 4.1 and 5.5 mm respectively, equivalent to 24 mm and 32 mm, and the focal length difference is about 1.3 times. The 1.3 times focal length difference of the two cameras, plus 0.8 times pixel difference, is close to 1.6 times. However, the actual wide-angle/view range of one plus 5 is basically the same as the equivalent 28mm one plus 3T. The equivalent focal length of 24mm is estimated to be a system information error.

The one plus five telephoto camera failed to achieve twice the optical focus as the iPhone. The main reason may be to balance the size and thickness of the sensor (the iPhone is only 1/3 inch). Compared with the iPhone optical telephoto, the main disadvantages of one plus five are the magnification and the ability to visualize at the same distance (affecting the portrait mode). The advantages are that the field of vision/wide-angle is larger, the amount of light in the same situation is more, the requirements for anti shake are lower, and the image quality will be better.

In terms of photographing experience, Yijia, like iPhone, has added a 2x zoom button beside the shutter, which can be used for fine "focusing" by sliding left and right. However, there is still room for improvement in the interaction between images and button responses when zooming continuously.

Although the portrait mode that needs algorithm accumulation still has a way to go, the telephoto lens+20 million pixel sensor+sharpening algorithm, one plus five, can easily overwhelm the iPhone's 12 million pixel true 2 times telephoto. Although there is still a small problem with white balance, the daytime scene effect is outstanding.

One plus five also retains the distinctive HQ mode. The official explanation is the "pixel optimization" technology, which can effectively reduce the background noise when used in good light, and improve the discrimination and detail perception. It may be that the firmware has not been fully optimized, and the HQ mode of one plus 5 is more likely to have local blurring than that of one plus 3/3T (sometimes the HDR+of Pixel also has the problem of local composite blurring).

In the weak light scene, compared with the automatic night scene noise reduction, the HQ mode will appear more detail noise, but the ISO is lower, and the discrimination remains intact. Now there is no waiting picture for multiple consecutive shots, which will not affect the photographing experience. It is recommended to open it for a long time. If you find that the photo taken by your mobile phone is not as strong as what the media said, please check whether the HQ mode is enabled (the sample below uses the HQ mode uniformly).

The actual film performance of one plus five is slightly better than expected, the white balance and photometry are slightly more accurate than the previous generation, and the color saturation and contrast are higher, more pleasing to the eye. Even if the weak light scene can achieve the level of small input and 3T, the noise control is commendable, but if the light is slightly worse, it will be thrown away by the S8 and iPhone of the large pixel scheme.

In light and weak light scenes, where the "high pixel+optical anti shake" scheme has the greatest advantages, it is very embarrassing to compare one plus 5 with one plus 3T. The main weakness of one plus 5 and one plus 3T is the extremely weak light strain inherent in the small pixel (especially the unit pixel size) scheme.

After almost all the products of the same generation have "returned" 12 million pixels, one plus five has obvious pixel advantages in the sunlight and lighting environment with good light, but after the light gets worse, the image quality will deteriorate faster than the products of the same generation with large pixels.

Summary

Although virtualization and telephoto are added, the overall photographing level of one plus five is still backward, and the most obvious regression is the light scene most commonly used by users. The actual proof sheet tells you cruelly that, even if one plus five uses a sensor with a small increase, the light input will increase by 34%, but the large aperture scheme is still inferior to the one plus three thirds of the one plus three with an old sensor+optical anti shake, and still loses a lot.

The IMX398 sensor itself of One Plus 5 has significantly improved the problem of the occasional slow focus of One Plus 3/3T and the slow focus of dot weak light scenes. The new ISP of Snapdragon 835 also brings faster multi frame synthesis speed, so that the HQ mode of the signboard no longer affects the use experience. However, if we give up optical anti shake to add some immature functions such as virtualization and telephoto, it is really not worth the loss. As an aside, the Maoists can only feel helpless for the collective photography in the transition period of double photography.
