Understanding Shutter, Mirror and Total Release Counts

 

Cameras have 3 Counts:

1. Shutter Count.  The Total Release Cycles of the ‘Current’ Shutter.
2. Mirror Count.  The Total Release Cycles of the ‘Current’ Shutter.
3. Total Count.  The Total Release Cycles of all ‘Current and Past’ Shutter and Mirror releases.

 

Release Cycles / Total Count

Of the three, Total Count is the often misunderstood for two reasons:

• Many models display ‘Release Cycles’ in their menu.  Owners might believe this to be the shutter count and expect the number to change after a shutter replacement.
• Many 3rd party Shutter Count software report ‘Release Cycles’ as the ‘Shutter Count’.  Again leading to misunderstandings after a shutter replacement. 

 

 

Release Cycles - In the Camera Menu

(The Total Release Cycles of all “Current and Past’ Shutter and Mirror releases!)

 

 

SPT Software displays the current Shutter, Mirror and Total Counts

(Read directly from the Camera's EEPROM)

* The Total Count are rounded

 

After replacing the Shutter (or Mirror Box) the Shutter count is changed to ‘0’

 

Resetting the Shutter (or Mirror) Count 

Does NOT and SHOULD NOT change the Total Release Count

The Total Release Count is the camera’s odometer … it is the cameras milage meter.

 

SPT Canon Software automatically records the Shutter (or Mirror) changes

Including Dates and Release Counts
