What's the core of a camera? It's a sensor. In the era of film camera, film is sensor; In the digital age, sensors are also changing from CCD to CMOS. The function of the sensor is to convert the external light signal into the electronic signal and become our photos. It's not that our country can't build sensors because of the complexity of this technology. Think about our 5g technology, our rockets and space stations, our high-speed rail and aircraft, which is not more difficult than sensors. It's not that they don't build it, but that no one is willing to spend money on it. The proction of CMOS sensor, then we need to use the lithography machine. The photoresist can make both chip and sensor. At present, our country has developed a photoresist that can proce 22nm chips, but the mainstream photoresist technology is still in the hands of ASML (Netherlands) and Nikon (Japan) and other brands

many of the technologies we have mastered are still inherited from the era of film cameras in the last century. The application of these technologies to digital cameras has been very backward. However, new technologies have not been developed and are now in a state of abandonment. Therefore, it is even more difficult for us to realize the localization of SLR camera or micro single camera without technological breakthrough in every link
