Is SLR the best camera?

SLR only says that it is more professional in the camera field and has better integrated performance.

But there is no "best".

Because what does "best" mean?

SLR, technically speaking, "single" refers to a single lens, and now they are all single-lens cameras (there were also double lenses before, such as double-reverse); "Reverse" refers to the reflector.

So from a technical point of view, the current cameras can be divided into "SLR" and "no reflex".

According to the principle of SLR, the reflector is mainly used for focusing, light sensor, RGB sensor, framing, etc., which has no direct influence on the image quality; It is only used to improve the overall performance of the camera.

It is called SLR because there was a "double opposition" before. However, this technology has fallen behind and has now withdrawn.
