A single-lens reflex camera, or DSLR, is the modern-day equivalent of a film camera. These use digital storage, often in the form of secure digital (SD) cards, which are a cheaper and sturdier alternative to rolls of film. In addition, the time required to gain access to digital photos is far shorter, as no development is necessary. However, DSLR cameras are generally more expensive than standard film cameras, due to their more complex electrical components. Despite this difference in cost, the resolution of DLSR cameras is not significantly different than that of film cameras, with the two having tens of megapixels.

According to PetaPixel, a new generation of mirrorless camera technology is gradually overtaking DSLR cameras. These innovations are lighter weight and utilize smaller, faster lenses for burst shots. Additionally, the proliferation of smartphones offers the convenience of simply reaching into one’s pocket to snap a decent photo, which is gradually edging out the niche that digital cameras formerly occupied. However, certain components of a DSLR, such as the viewfinder and image sensor, can be found in mirrorless cameras. But what’s inside a DSLR camera?
