The ZEISS brand is actually very good, whether it is a small eyeglass lens in daily life, or an optical lens in an ASML lithography machine, you can see its figure - it is simply a god-like existence in the field of optics.
As for the ZEISS T* coating used in the blue factory, it is actually a combination of the red letter T (single coating) and the red mark* (multi-layer stacking), as can be seen from the figure above The significant advantages of T* multilayer coating in terms of transparency.
In addition, because the lens is made up of multiple elements, the anti-reflective ZEISS T* coating eliminates light that is reflected multiple times inside the lens – i.e. anti-glare and ghosting reduction.
The reason why we want to talk about the ZEISS T* coating equipped with the flagship main camera of the blue factory is because it has never been explained in detail before, and on the other hand, it is to lead to the more bullish ZEISS APO certification. So, what exactly is APO?
Since white light is composed of seven colors of light, it will be separated by the different refractive indices of each color when passing through the lens, resulting in the final focus on different points and resulting in chromatic aberration - the "purple edge" is the most intuitive chromatic aberration phenomenon in daily photography. In addition, because chromatic aberration is amplified as the focal length increases,Therefore, when designing professional equipment such as telescopes, camera telephoto lenses, and microscopes, APO (Apochromatic, or the abbreviation of Apochromatic) technology is particularly important.
Therefore, on the basis of advanced optics and materials design, ZEISS uses the multi-color offset curve equation to compound the apochromatic of F and C rays (located at both ends of the sensitive spectral region of the human eye) under a specific aperture band, so as to design the super APO lens.
The earliest ZEISS APO work on the camera side was the Zeiss APO-TESSAR lens from 1923, and now it happens to be a hundred years old – the ZEISS heritage in APO camera lenses can be seen!
The Blue Factory claims that the Zeiss Vario-Apo-Sonnar macro telephoto lens used in the X100 Pro will be based on the strict standards of ZEISS traditional camera APO lenses, and will be panned to mobile devices, bringing excellent chromatic aberration control and color correction to mobile phones.
It can be seen that the blue factory has a bit of a "glance" flavor in the optical quality of the dead lens - there is a Zeiss T* coating in the front and Zeiss APO certification in the back. It is worth mentioning that the T* coating of this generation of main camera has also been upgraded!
Compared with the previous generation of V2 chips, the V3 image chip process developed by Blue Factory has been upgraded to 6nm process, with multi-concurrent AI-aware ISP architecture and second-generation FIT interconnection system, and the energy efficiency ratio has been greatly improved by 30%.
Among them, multi-concurrent AI perception means that multiple lenses can be driven to participate in AI computing at the same time, so as to realize the "image fusion" of multiple lenses with different focal lengths in ** shooting - corresponding to the official announcement of "cinematic bokeh bokeh, fully automatic subject focus detection and switching".
As for the abundant computing power brought by the second-generation FIT interconnection system, it can achieve the official claim of "cinematic skin texture optimization and cinematic color processing", thus forming a complete set of 4K movie portrait mode super experience.
Officially, the blue factory is the first mobile phone manufacturer on Android that can realize 4K movie portraits**, as well as Android's first 4k-level post-shooting editing function. In fact, at the X100 series press conference, the blue factory showed some real-life micro films, and the overall performance was really good.
In addition, the blue factory has also built a set of composite algorithm matrix, in which the VOIE (blue factory original image engine) includes three sub-modules: ultra-clear image quality, color restoration, and computing power acceleration, which are upgraded for image quality, color tone, and computing power.
Finally, combined with the two core user scenarios of portrait and night scene, two sets of algorithm systems were created: the super-sensitive portrait system and the sky night scene system. In other words, the blue factory that is already very good at portrait algorithms, now it is directly at the level of "seeking defeat alone"!
Of course, such a great hardware and algorithm configuration is definitely not enough to be used on the main camera. Therefore, the blue factory combined the original image engine and the Zeiss APO telephoto, and directly created the "telephoto hanging sun" gameplay - the lens optical quality is good, you can do whatever you want!
Blue Factory has always liked to brag, so as long as it is the characteristics that it focuses on, there must be something unique - just like the X100 Pro's main camera (precision jump optical tuning plus upgraded T* coating) and periscope performance are just as amazing!
In addition, the Periscope also uses a "D-cut-free" design, which means that there is no compromise on the size of the module to cut the effective part of the lens, which solves the problem of aberrations and improves the resolution of the lens (which is also available in the standard version).
Coupled with the ZEISS APO macro telephoto lens, which significantly improves the "purple fringing" phenomenon and color degradation at the edges, as well as the convex lens (concentrating) and large aperture design configured above the prism, the optical buff is stacked!
As for the V3 chip, it is actually an "ISP+NPU" complex with its own cache system, which can perfectly cooperate with the SOC to cope with the ultra-large throughput required by the flagship-level imaging system, thus bringing the "telephoto hanging sun" gameplay.
