Digital photography is now more accessible than ever before, thanks to cameras that can autofocus and store hundreds of photographs on their internal memory cards, making it suited for both professionals and amateur photographers.

However, knowing your camera options before making a major investment is essential.

A digital single-lens reflex (DSLR full form) camera (notable for permitting interchangeable lenses on the same camera body) is one form of digital camera. (DSLR Definition)

When light reaches the camera lens of a digital SLR camera, it is reflected by a mirror inside the camera body, allowing the photographer to see their subject via the optical viewfinder.

When the shot is taken, the mirror swings out of the way, enabling light to flow through to the digital image sensor, which saves the image to an SD card.
Unlike mirrorless cameras, where light is sent directly to the image sensor and the photographer sees what they're shooting through a back LCD screen or an electronic viewfinder, the photographer sees what they're shooting through a rear LCD screen or an electronic viewfinder with this camera.
