There is no resolution or workaround unless Canon changes this behavior. Note that the built-in shutter counter on the EOS-1D X is also affected by this phenomenon. Or the easiest way to reproduce this phenomenon is to power the camera with a DC adapter and just pull the plug. But when the battery runs too low during shooting, it might not provide enough power for a proper shutdown. So it's hard to cause an abrupt power cut this way. The time it takes to fully open the door is usually enough for the shutdown. When you remove the battery the first thing the camera does after detecting that the battery door is open is to shut itself down properly. If power gets cut abruptly, then the camera fails to do a proper shutdown and will not add the session count to the non-volatile count - resulting in "missing" shots. It is incremented during the session and added to the non-volatile count when the camera is turned off. The session count is zeroed when the camera is powered on. What ShutterCount displays is the non-volatile count. There are two numbers: a non-volatile count and a session (volatile) count (a session is the time interval between power-offs). The cause of this shutter count discrepancy is how Canon's firmware counts actuations.

But ShutterCount displays a lower value, 8950. Q2 - Shutter count value is lower than expectedįor example you bought a camera new, the EXIF file number was not reset, and the current EXIF number shows that you have 9400 shots. In case of the 5D Mark III the fist version known to work correctly is 1.2.1.

You should update to the latest available firmware. As the camera chops off the lower 32 bits, only the upper 32 bits are returned giving the value 7. Using the above example, the full 64-bit serial number in hexadecimal representation is 00000007 EB64059A. There is a bug in older Canon camera firmware revisions that chop off the lower 32 bits of the serial number, thus returning an incorrect short string. For example, instead of 034012005786 on an 5D Mark III you get just 7. Instead of the correct serial number ShutterCount displays a small number. Q1 - Serial number not displayed correctly
