The Canon EOS 5D Mark IV has an expected shutter count of up to 200,000 actuations, although this life expectancy can be extended if the camera is well-maintained and regularly updated with its latest firmware.
In fact, some users have reported reaching 300,000 actuations or more if they mainly use their camera for night shots or static photography.
To ensure that your camera will last as long as possible, you should keep it in good condition and make sure that it always has the most current firmware updates. Doing so will help prevent any unexpected issues that may affect its performance.
