In fact, the telephoto change of the green factory super large cup this time is very simple, that is, there is an extra 135mm periscope. Of course, through actual measurements, it can be seen that the telephoto super-resolution algorithm of the green factory has made rapid progress this time, so the fusion telephoto strength of the two periscopes cannot be underestimated.

The IMX858 sensor equipped with the new Periscope, although it has been seen on the Xiaomi 13 Ultra, its 135mm focal length is slightly better than the 120mm of the Xiaomi PeriscopeAt the same time, the "1G+3P" lens group structure can also bring better lens optical quality.

When the new machine was not released before, Liu Zuohu showed Hasselblad's XC135 lens - this is a portrait weapon known as the "king of bokeh"!Therefore, the glass lens added this time is the corresponding essence of hardware, and let's talk about its use.

First of all, the biggest advantage of glass lenses is that they are not sensitive to temperature, so they can use multi-layer optical coatings - although I don't know if the green factory has coated this lens this time, but its anti-thermal expansion and contraction characteristics are also a natural advantage.

Then there is the "ultra-low dispersion" characteristic emphasized by the green factory, which is very important for telephoto lenses, so the "curative effect" obtained is that the image color is more vivid, and the picture is sharper.

In other words, a small glass lens can bring more vivid and sharp imaging results, combined with the background blur effect brought by the algorithm, which is not in line with the Hasselblad XCD135's "sharp image quality and soft bokeh" characteristics

As for the IMX858 sensor, it has a 12-bit ADC that can reduce dark noise in high-dynamic scenes, as well as LN2 low-noise mode that further enhances noise control, and "multi-camera collaboration" is also a highlight - more consistent colors and smoother switching.

On the whole, in the field of 6x fixed coke, the performance of the Hasselblad custom periscope of the green factory can be said to be in line with expectationsCombined with the most proficient portrait algorithm of the green factory, it is basically the existence of Dugu in terms of telephoto portraits.

Of course, the IMX858's "2 2 OCL" design is certainly a disadvantage for extreme digital zoom. However, with the blessing of the green factory's fusion of telephoto algorithm and super-resolution algorithm, even if it is magnified to 60 times, it will not lose X100 Pro, which is far beyond expectations.

So, how did the green factory overcome the problem of resolution this time?On the dark periscope side, by cropping **12 million pixels in high-pixel mode, an equivalent 6x optical focal length can be achieved.

The Hasselblad Periscope can also achieve an optical focal length equivalent of 12 times in the same way. Combined with the equivalent 2x optical focal length of the main camera, three equivalent optical focal lengths and three optical focal lengths can be obtainedThrough the imaging cooperation of these six optical quality focal segments, the digital zoom result can be synthesized with the fusion telephoto algorithm, and then the super-resolution algorithm can be used to optimize the details, and finally a clear ultra-telephoto image can be obtained.

In this way, in the end, it comes back to the ultimate question, which is better, the dual periscope of the Find X7 Ultra and the Zeiss APO periscope of the X100 Pro. First of all, in terms of extreme night scenes, there is no doubt that the IMX890 periscope of the green factory wins.

Then there is the telephoto portrait aspect, although the portrait algorithm of the blue-green factory is very good-the advantages of the offline manufacturers for many years, but the green factory wins in the native focal length has one more choice, and at the same time, the 135mm periscope performance here is extremely good. As for the long-term ability, the green factory has also entered the first echelon this time.

On the whole, the only thing lacking in the green factory is the telephoto macro function that the X100 Pro has. This feature has been widely praised since the launch of the Huawei Mate50 RS, but the green factory chose to ignore it, which is a small pity.
