This is one actuation and adds one to the shutter count. Each time you take a photograph the shutter mechanism moves back and forth across the sensor at a precise rate according to the shutter speed you selected. The photo below shows the basic designs for both DSLR and the mirrorless camera.ĭSLR cameras have a mechanical shutter mechanism to cover and expose the digital sensor. They’re interchangeable-lens cameras you can swap out the lens and attach another type of lens. While DSLRs and mirrorless cameras have many characteristics that differentiate each other, they do share one important feature that separates them from all other types of cameras. A camera’s lifespan also depends on many other factors, such as care, servicing, and environmental conditions. It is the same situation as when you are evaluating the conditions of a used car you always check the vehicle’s mileage.
Knowing that moving mechanical parts will be worn faster because of friction and wear, the main factor to establish a life span of a camera is figuring out its shutter count, which is the number of times the shutter has fired.
The most important parts are the shutter mechanism and the motor that flips up the mirror in a DSLR. Modern cameras have complicated electronics, but only a few moving mechanical parts.
