Understanding Release Counts

Shutter / Mirror / Total Counts

Cameras have three important counts:

1. Shutter Count: This is the total number of times the shutter has been released.
2. Mirror Count: This is the total number of times the mirror has been released.
3. Total Count also known as the Release Count: It is the sum of the Shutter Count and Mirror Count, including all past shutter and mirror replacements.
