camerausually performs admirably until it is completely ruined. Even yet, a camera can live for more than five years, and if you are a hobbyist photographer, it can last even longer. Instead of looking up the camera lifespan, you should take care of your camera and update if it is much older, as the shutter count cannot be reset.
A medium-level camera has a shutter count of 150,000, which means a user can take about 90,000 photos in 5 years. Of course, knowing your camera's shutter count is preferable, but it doesn't imply you should be concerned or count every single click.
