The SLR camera is called a single-lens reflex camera. The single lens is a
photographic exposure light path and a viewing light path share the same
lens, and there is no independent lens with a double reverse camera. "
Reflection" means that a flat reflector inside the camera separates the two
light paths. When the lens is shot, the reflector falls, reflecting the
light of the lens to the pentaprism, and then to the viewing window.
At the time of shooting, the reflector lifts rapidly, and the light can
shine on the film or the photosensitive element.
The structure of the SLR camera is: lens set, 45-degree reflector can be
lifted, fast curtain, film or photosensitive coupling element, focal screen,
focusing lens, pentaprism, observation window.

When the shutter is pressed, the reflector of the SLR camera rotates upwards
, the fast curtain in front of the photosensitive formation is opened, and
the light is projected through the lens onto the photosensitive element, and
a photo is generated. The reflector plate is a very special configuration,
because her body can not develop in a miniaturized direction, so the SLR can
not be as light and convenient as other paraxial cameras.
The biggest advantage of a SLR camera is that the photographer can directly
observe the image through the lens from the viewfinder. The term is called
single-axis reflex viewing.
Warmth tip: all cameras that can change lenses are not all SLR cameras. For
example, paraxial cameras, double reverse cameras, and non-reverse cameras
can also change lenses.
The SLR is just a structure. It has nothing to do with the quality of the
picture. It is not professional. It wants to take good photos. The emphasis
is on taking more pictures.
