There’s no tool that works seamlessly for all EOS models, let alone on both Windows and Mac platforms. Interestingly, there’s no official Canon based application to find the shutter count for an EOS DSLR, however, there are a few free online tools that may help you to do this. There you can find out the average life expectancy for your EOS model(s). In fact, the Camera Shutter Life Expectancy Database is a really neat user-based site for DSLR models of several brands, including Canon. Typically this count is between 100,000 and 300,000 shutter actuations, with the latter limit associated with the EOS-1D models. Usually, you’ll have to take a couple hundred thousand photos before this happens though, and Canon has allegedly released a particular shutter actuation threshold to indicate the number of shots expected for each EOS model before the shutter fails. At this point, you may either need to have the shutter replaced or purchase a new camera.

Sooner or later, your DSLR’s shutter will wear, slow down and eventually stop functioning. Just as with any piece of mechanical equipment, a camera has a lifetime that is based on the number of shutter actuations otherwise known as shutter clicks or the shutter count. Shutter Count Number is important – A DSLR’s shutter will eventually fail
