DSLR: What it is & How it works

The Canon EOS 5D MKIV is a digital single-lens reflex (DSLR) camera. With DSLRs, the light enters the camera lens of a digital SLR camera, the photographer operating the camera can see their subject in the optical viewfinder via a reflection of that light from a mirror inside the camera body. As the photographer takes the photo, the mirror swings out of the way, and the light goes through the digital image sensor to capture the photo on an SD card. This is different from mirrorless cameras, where the light goes directly to the image sensor, and the photographer sees what they're shooting via a rear LCD screen or an electronic viewfinder.
