Last year's hammer T2 only carried the "IMX214+optical anti shake" scheme of the previous year, but this year's hammer M1L, in addition to Snapdragon 821, also carried the latest flagship standard configuration - "IMX318+optical anti shake" scheme. This sensor with 23 million pixels and 1 micron unit pixel size has also appeared on the Zenfone3 Zunjue and Aoshi versions of ASUS. Now let's see how it will behave under the guidance of Hammer Technology.
Investigation items and scales
The core of mobile phone photographing is the photographing experience and imaging effect. The main factors that affect the experience are:
Viewfinder Smoothness and film consistency: whether the frame of view has problems such as delay/shadow dragging/frame dropping/full screen noise;
speed And also includes focusing speed, shutter response and imaging speed;
Film rate , the probability of destroying the film by shaking hands;
Degree of automation , whether it can identify the scene with large light difference and weak light, and automatically trigger HDR and night view mode;
The imaging effects mainly include:
White balance and photometry In many scenes such as sunlight/light/weak light and extremely weak light, whether the white balance (picture color and wind direction) and brightness can be close to the naked eye;
Discriminative power Roughness can be understood as clarity, and the sharpness, detail and naturalness of the picture must be taken into account at the same time;
Tolerance , that is, the ability to show details in the light and dark at the same time. For mobile phones, this is basically equivalent to whether the HDR effect is natural and harmonious, whether there are ghosts, white balance deviation, and poor discrimination after synthesis;
The remaining assessment contents include noise control, color saturation (the closer to the naked eye, the better, but Samsung and Huawei will be able to raise it recently to please users), lens quality (including edge degradation control, anti glare, fog control, wide-angle and pillow deformation control, etc.), and many other contents.
Although everyone's requirements for photographic experience are almost the same, for different users, the proportion of different imaging projects is completely different: for example, the number of Maoists who like to enlarge photos and scan will definitely put discrimination first, and the proportion is very high; The party in the circle of friends attaches great importance to tolerance, white balance, saturation and other items, but the requirement of discrimination is not high. Therefore, the comparison will be divided according to different items, and it will be better for everyone to focus on understanding what they care about.
Photo experience
Note5 Photo taking interface
One plus three photographing interface
Hammer M1L photo interface
The photographing experience of Hammer M1L is still 1-2 years ago, and there is a clear gap between its intelligence and speed and the mainstream flagship of OnePlus 3 and Note5.
Camera interface, viewfinder and Intelligence ： One plus three is the minimalist style of native Android, and Note5 has many quick adjustment functions. In contrast, the photo app of Hammer M1L looks very old. During weak light shooting, the hammer M1L will have obvious jamming and frame dropping, which is not a problem with the other two machines, and it also It is the only one of the three machines without automatic night view and HDR functions;
Shutter HDR and night scene processing speed: The daytime response speed of the Hammer M1L camera is fairly good. In the night view mode, there will be no shooting jam, but the shutter will have to wait about 2 seconds to continue to respond, but HDR is very, very slow. After clicking the shutter, the shooting and shutter will be stuck for about 3 or 4 seconds, It must be the slowest flagship in HDR mode in recent years. Even hammer T2 has no such problem, which is likely to be a problem with the current version of the system.
Focus success rate vs Film rate: The focusing performance of hammer M1L is satisfactory, close to the level of one plus three, but the film rate is low, and it is easy to damage the film due to focusing and shaking hands;
Wide angle&lens quality
Compared with the sample size, the sample size of hammer M1L with 23 million pixels is a whole circle larger than that of hammer T2. On the contrary, there is no obvious difference between the 13 megapixel T2 sample and the 16 megapixel Note5/One Plus 3 sample.
The equivalent focal length of hammer M1L is maintained at 28mm, and the wide angle is consistent with Note5, which is smaller than one plus three. After equal magnification, the same object is much larger on the hammer M1L, and the size of the object in the 16:9 frame of Note 5 is slightly larger than that of one plus three. If other conditions remain unchanged, the advantage of the hammer M1L in discriminant force will be very obvious.
The lens module on the hammer M1L is well matched. Glare control Several machines perform well. Note 5 and hammer T2 are relatively weak, and one plus three is similar to hammer M1L (M1L has smaller light spot due to serious insufficient exposure).
Edge degradation, Compared with the picture in the lower left corner, the edge degradation control of hammer M1L is amazing, even more than Note5, which is not less than one plus three.
White balance/metering/contrast/tolerance contrast
This part of the sample is used to compare the white balance, photometry and color saturation, and the discriminant force sample is concentrated in the last part
The focus of all samples is at the center. Note 5 is in full automatic mode, one plus three full HQ mode. Hammer M1L and Hammer T2 select samples with better performance as representatives in night view and automatic mode.

Hammer M1L Poor HDR effect , only slightly better than the reciprocal Xiaomi and Meizu of domestic HDR. Its HDR mode has little impact on white balance, but it will significantly improve the metering, and the dark details are dyed very clearly, which can be directly distinguished even without looking at the file name and size (the size of the sample will be slightly smaller in HDR mode).
Hammer M1L under strong light Underexposure Tendency of The light scene is close to the naked eye, and it is easy to underexpose when the light is weak, and the weaker the light is, the more serious the underexposure will be (the brightness of the extremely weak light scene is not as bright as T2, and it is basically black, 1 μ The m unit pixel size seems to be laborious).
In terms of white balance, the hammer M1L is relatively stable, and there will not be too much drift. In contrast, like Huawei P9, there is a slight increase in contrast, which makes people feel more transparent, but tolerance is also affected. It may also be related to the ultra small unit pixel size, which is not available in other machines when the light becomes weak Saturation decrease Problems.
Overall, slightly Enhanced contrast +Ultra small unit pixel size Decreased saturation and sensitivity+ The HDR algorithm with low availability has no advantage over the previous generation in the look and feel of the Hammer M1L sample, and is under greater pressure compared with the flagship ranking high.

The sample of hammer M1L is obvious Crisp Enhancement , but because the pixels are higher, the white edge caused by sharpening is slightly smaller than one plus three. M1L The advantages of limit discrimination are obvious Even though the HDR mode will reduce and sharpen the effect, the contours and details of various objects are more abundant, but the noise control at fine points is general.
Unfortunately, the 1-micron unit pixel size of the IMX318 makes the ISO growth rate and image quality decline after the machine's light gets worse, which is much faster than other 1.12-micron+optical anti shake schemes: It is slightly weaker than 1+3 and Note5 under normal light, and even T2 cannot win under weak light And there is a serious problem of insufficient weak light exposure. The only thing to be commended is that the noise control of hammer M1L is good, and even if the ISO exceeds 1000, it also has a good picture purity.
Summary
Hammer M1L is a conventional optical anti shake IMX318 performance. The latter has high pixels but low unit pixel size, which means that weak light performance and tolerance are weaker. It can be summarized as "light intensity is strong, light intensity is weak". although There is still some distance from the first echelon of photographers, Weak light and extremely weak light performance is not as good as hammer T2, but the discrimination in most environments is significantly improved 。 The main problems of the M1L camera are Photo experience (focusing, film rate, HDR, night view mode speed, etc.) and Weak light performance 。
