What is a SLR digital camera and what does SLR mean?

Single-lens reflex camera, that is, a single lens refers to using the same lens to view and shoot, and reflex means that the image is refracted by the reflector and seen by us.

A SLR Digital camera refers to a single-lens reflex digital camera, which is the English abbreviation DSLR for the four English words "digital, Single Single, Lens Lens, reflex reflex". Representative models in the market are common in Nikon, Canon, Pentax, Fuji and so on.

Another common fool camera, the framing and shooting lens are separated, and the framing is generally in the upper right corner, and it can be seen directly through the framing window, and there is no reflective device.

Advantages and disadvantages of the two: SLR framing uses one lens, and the framing picture is the picture in the photo, while the silly framing picture is slightly different from the photo because of the position deviation; SLR is heavier, fool is lighter; SLR is usually suitable for creation, and fools are suitable for snapshots; A SLR can change lenses, but a fool can't.

So a good photographer usually has two kinds of cameras: SLR and fool.
