Mirrorless

Sony uses "mirrorless" cameras in its compact, interchangeable lens digital cameras. Sony positions the "mirrorless" camera as a cross-border product between a digital SLR camera and a card camera. Its most important structural feature is that it does not have a reflector or prism. "Micro-Single" is a trademark of Sony Corporation.

A new word, mirrorless has been given two meanings: micro, micro and compact; SLR, the picture quality of an SLR camera. In other words, this word means that this kind of camera has a compact size and SLR-like image quality.

In June 2010, Sony launched its first “mirrorless” cameras—NEX-5 and NEX-3. "Micro-single" cameras have the characteristics of combining portability, professionalism and fashion. The customer groups targeted by "mirror-single" cameras are mainly those who want to obtain very good picture performance on the one hand, and want to obtain a compact camera on the other. The target customer group of digital cameras is their portability.

In addition, due to the 18mm flange distance and the same size as the CMOS sensor of today’s mainstream SLRs, it is very suitable for adapting a large number of manual lenses passed down in the early years. Therefore, NEX mirrorless cameras are very popular among photography enthusiasts There is a huge market in China!

Because mirrorless cameras are lighter and have more styles than SLR cameras, they have a large market among women.

Origin of technology

The history of human development proves that no technology can be brilliant forever. In the film era, film, the medium for storing images, must be strictly protected from light leakage during framing. However, in the digital age, the situation has fundamentally changed - CCD is not afraid of light leakage. It can be used for viewfinding, and can also be used for imaging after clearing. Therefore, the necessity of the existence of a reflector has been greatly reduced. Its working principle determines that the viewfinder of a reflector is not suitable for digital photography. On an electronic digital camera, there is no need to retain a mechanical component - the reflector. Although people can tolerate the bulky and complicated structure of the reflector because it can take into account the ability to view the view through the lens and protect the film from light leakage, the characteristics of image sensors in today's digital era that are not afraid of light leakage make the existence of reflectors no longer necessary. , with the improvement of electronic viewfinder technology, one day, the clarity and brightness of electronic viewfinder will be good enough to replace the reflector. Therefore, in theory, a single-lens camera can have almost all the advantages of a single-lens reflex camera - better image quality, greater depth of field, and interchangeable lenses. Once demand breaks out, such problems will definitely be solved, and the size of a single-lens camera This is an advantage that SLRs can never catch up with.

Before Sony launched a "mirror-less" camera, consumer electronics giants such as Olympus, Panasonic, and Samsung had already launched mirrorless products that used electronic viewfinders and could replace lenses like a SLR. It's called a "single electric camera". Hidehiko Teyogi, director of Sony's Personal Audio and Video Division, said that "Micro-Single" is a trademark specifically targeted at the Chinese market, and its products have been given two meanings: micro and SLR: the camera is micro, compact, portable, and can be replaced like a SLR camera. lens and provides the same image quality as an SLR camera.
