It should be noted that shutter actuation is a statistical value, and there always be flukes in statistics. For instance, Nikon publishes shutter actuation of their DSLR line-ups using the words "tested to over 100,000 cycles", meaning that the shutter is expected to last some time past the 100,000 cycles mark. Usually these figures are pessimistic and the actual model may last more than the rated lifetime. Entry level DSLR cameras usually have low shutter count, but nothing below the 100,000 mark while professional-grade camera are robust enough to last 300,000 shutter actuations and beyond. Replacing a shutter can cost anywhere between $100 to $300, depending on your camera model, which is cheaper than purchasing a brand new camera.Ī typical DSLR camera shutter will last between 100,000 to 300,000 shutter actuations. When the shutter fails, you may either need to have the shutter replaced or purchase a new camera. The part that usually gives up first is the shutter. Sooner or later, these components will wear out and eventually stop functioning.
Aside from the shutter, a DSLR camera has additional mechanical parts – the mirror system, the very heart of an SLR camera, that moves up and down with each shutter release, and sometimes focusing motors. The shutter count is the number of times the shutter is activated – that is, the shutter button is pressed causing the shutter blades to open and close. The life of an SLR or Digital SLR camera is based on a number of factors, one of which is shutter actuation or shutter count. A camera is a mechanical device, and just like any piece of mechanical equipment, it will eventually fail.
