Before somebody gets into the rigmarole of engaging a camera to go shopping, understanding the mirrorless-camera and traditional DSLR differentiation is fundamental. The two types are pretty different and cater to distinct needs.
Basically, DSLR cameras have a mirror mechanism to channel the light entering through the camera lens into the optical viewfinder, a rather old-school way of shooting. They are often large and heavy but are appreciated for longer battery life and gigantic lens selections.
In the mirrorless-camera system, the image sensor gets light directly, along with the electronic viewfinder or screen through removing the concept of nature of the mirror. This has made the system compact and light while providing fast autofocus and continuous shooting speeds.
Once upon a time, the DSLR cameras were more famous; now, with their stark modern features and small sizes, the mirrorless camera is outshining them. Having some knowledge on the difference between mirrorless and DSLR camera technology helps a photographer select a system that fits his needs as a professional or casual shooter.
