What is the principle of a mirrorless camera? What's the difference between a mirrorless camera and a SLR camera?

Abstract: What does a mirrorless camera mean? A mirrorless camera is a kind of camera without a mirror, also known as a half-lens camera. Is the mirrorless camera a micro-single? Microcells are mirrorless cameras, but mirrorless cameras include microcells and single cells. What is the principle of a mirrorless camera? What's the difference between a mirrorless camera and a SLR camera?

What does a mirrorless camera mean? Principle of mirrorless camera. The difference between mirrorless camera and SLR camera.

The term "mirrorless camera" is relative to SLR cameras, such as micro-single cameras and single-camera cameras (except Sony semi-lens A series) used by manufacturers in advertisements. There is no unified name for this camera at present.

Essentially, the biggest difference between a mirrorless camera and a SLR camera lies in the way of framing. When a SLR camera takes a view, the light enters the camera from the lens, and then the light reflects upward through the mirror (negative) in front of the sensor and enters the pentaprism, and then the user can see the picture that can be shot by the lens through a series of refraction of the mirror. However, in a mirrorless camera, the mirror structure is cancelled, and the light enters the direct sensor of the camera through the lens, so the framing method in a mirrorless camera is electronic framing.

Behind the lens of SLR camera is a reflector.

Behind the lens of a mirrorless camera is an image sensor.

Generally speaking, we still remember the used card camera, which is the predecessor of the mirrorless camera. Its principle is the same as the current mirrorless camera, the only difference is that the lens cannot be changed. Today's mirrorless camera can be considered as an advanced form of card camera.

It has been six years since Panasonic released the first mirrorless cameras in 2008, and mirrorless cameras has also developed rapidly in recent years, with various forms coexisting. Whether it's a paraxial camera like Olympus PEN series or a SLR-like camera with a built-in viewfinder like Fuji X-T 1, its essence is a mirrorless camera, so you don't have to worry about it.

So let's get back to the real problem. How do I choose a mirrorless camera or a SLR camera? What is the difference between the two in use?

After nearly a century of development, SLR cameras have become very mature in modeling, the number of lens groups and imaging technology. However, it is an indisputable fact that they are bulky and have poor portability. Moreover, for home users, the performance of SLR cameras is excessive, and low-end SLR cameras may not have a good experience due to serious configuration. Looking back at the era of film machines, have you ever seen SLR cameras all over the street? At that time, most of the household cameras were relatively small paraxial cameras (fool cameras).

They took all my childhood photos.

The mirrorless camera cancels the reflector and pentaprism structure, so the body volume is greatly reduced. The portability is greatly improved, and compared with the perennial black SLR camera, the mirrorless camera is relatively fashionable in form. But the weak lens group and endurance have become its biggest shortcomings. But there is enough home.

Simply put:

The difference between a mirrorless camera and a SLR camera lies in the framing method, not the imaging quality.

SLR camera is superior to focusing performance and rich resources, and it is a tool camera for photography and photography creation. Mirrorless camera is the best choice for family and travel because of its portability and fashionable appearance.

If you are a friend who wants to study, play and like photography, please choose a SLR camera. Rich lens group and excellent performance will make you feel the fun of photography.

If it is for home use (playing in the park, partying, taking photos, etc.). ), please choose a mirrorless camera. Portable size and fashionable body will make your journey easier, and it is also a symbol of taste and style.
