Supporting personalized module equipment is one of the biggest selling points of Moto Z. As the most favored module product by Lenovo, the Hasu module was said by Lenovo at the beginning of the release of Moto Z. "Mobile phones are used to take photos, and Hasu is used to take photos." It can be seen that this Hasu module is indeed highly expected by Lenovo, which also lets us Love to play computer games (Official account: Ainongji) I was very curious about its actual photo performance. Besides zoom, is this 2299 yuan Hasu photo module really better than the current smart phone photo taking?
Parameters and specifications of three cameras

In the daytime outdoor scene, we found that without optical zoom, The white balance performance of Hasselblad module is not ideal , there is a certain gap between iPhone 7 Plus and Moto Z native cameras. Moreover, this white balance problem is easy to reproduce, and it is not an individual case. When the sun shines on the ground, Hasu shows cool colors instead of warm colors.
Without zoom, It can be seen that the samples of the Hasselblad module have not been processed too much algorithm, and there are many original noise points The daytime resolution is basically the same as that of iPhone 7 Plus and Moto Z.
The effect of 10x optical zoom in outdoor daytime is very adverse. Basically, within tens of meters, everything you want to see can be seen through 10x zoom. The resolution of 250mm at the long focus end is OK. Although it is not as clear as the short focus 25mm close shot, it is completely acceptable in the daytime. But when you use 10x optical zoom, you must keep your hands steady, even in the daytime, because the jitter effect after 10x optical zoom is too great, even if your shutter is 1/100s.

In this set of scenes, the contrast focusing of Hasselblad module is weak, and the focusing time is about 3-5 seconds.

In the scene of this group of construction sites, after zooming in, we can see that both iPhone 7 Plus and Moto Z have applied the algorithm to the cement site in the distance, which is very obvious. The imaging of the Hasselblad module is still relatively original, and the algorithm processing effect is not obvious. In fact, this is a disadvantage.

In terms of weak light, the imaging effect of the iPhone 7 Plus is better than Moto Z, which is far better than the Hasselblad module. Moto Z's weak light resolution is actually not bad, but the exposure of the picture is too low, and the painting is not effective enough, which makes it appear noisy. The problem of the Hasselblad module has always been serious. Its imaging is not like taking pictures by a smart phone at all, but an old card machine. The algorithm is relatively backward, and is limited by the F3.5 ultra small aperture limit at its short focus end (25mm). Its imaging effect in weak light is poor. First, too small aperture is a congenital defect, and then the algorithm processing is not effective.
However, the effect of 10X light change is still good. Although the aperture of the long focus end (250mm) has been reduced to F6.5, the problem of using 10X light change in weak light is that your hand can't shake. In terms of experience, even the hand of God is not likely to be true at a shutter. It takes several shots to ensure that one is available.
Optical zoom of Hasselblad module

In the case of the same zoom, the iPhone 7 Plus can achieve the effect of 2x light change through the long focus (56mm). However, due to the quantitative adjustment of the light change of the Hasselblad module, it cannot be set to 2x light change. We can only choose the nearest 1.9 times light change for comparison.
Because the 2x zoom of the iPhone 7 Plus will automatically choose whether to use a 28mm digital zoom or a 56mm telephoto based on the sufficient light in the environment, and the telephoto will not be activated in the weak light at night, we use the daytime scene for comparison. From the results of the sample, it is obvious that the 1.9 times light variable energy of Hasu is stronger than the iPhone 7 Plus in analytical power. However, due to the algorithm and white balance problems, the iPhone 7 Plus also has its own advantages.
But in fact, the iPhone 7 Plus has lost since the moment it was compared with the Hasselblad module, because the telephoto of the iPhone 7 Plus is basically unavailable at night. Because of insufficient light, the iPhone will automatically select a 28mm zoom for 2x digital zoom, while the Hasselblad module is not limited at all.

The picture shows the contrast between the imaging effect of 10 times light variation through the Hasselblad module and the close-up shooting without zooming of the three modules.
Moto Z
This camera of Moto Z has no secrets. It is just an IMX214 with optical anti shake and large aperture. Its strength is limited and not too bad. It is reasonable that the weak light performance is not as good as that of the iPhone 7 Plus, but it is also acceptable. The problem with Moto Z is that the IMX214 does not have the phase focusing function. In some scenes, it will pull the bellows back and forth, and the overall focusing speed is slow.
Problems in Hasu module
In fact, as a photography module, people are most concerned about portability and effect. In fact, although the thickness of Moto Z+Hasu module has reached 20mm, there is no pressure to put it in the pocket. Here is a data for reference: the black card RX100 generation is the thinnest machine in the black card family, with a thickness of 35mm.
The problem of Hasu module is:
1. There is a gap between the image algorithm and mainstream smart phones. Taking pictures without focus is not as good as Moto Z's original rear camera, let alone compared with the iPhone 7 Plus.
2. The aperture is too small, and the weak light imaging is poor.
3. Common fault of optical zoom: imaging is easy to shake.
4. The focus is too slow in the distant weak light, and sometimes there will be false focus.
There are only two reasons to purchase Hasu module: light change and logo
If you want to get started with this Hasselblad module, your reasons must be zoom and logo, because apart from the super hyperopia effect brought by optical zoom, others are really not good. Don't expect it to be empty, because the aperture is too small, and don't expect weak light. There is no special color adjustment, which is different from Huawei's Leica color adjustment. If you take pictures with the Hasselblad module and compare them with other mobile phones, perhaps You will think the color is very bright, but this has nothing to do with Hasselblad. The reason why you think the sample is very bright is because of the AMOLED screen with Moto Z 2K resolution.
Under the halo of Hasu, you can take it out for photos in all kinds of occasions, or put it on the table at random when eating as a conversation topic between friends, which is also its social attribute.
