Hey Ken
IDK if you’ve found a solution, but I was curious about your issue. I love
timelapse but the process can be hard on digital camera bodies depending on how
the machine is built to execute the task. This kind of programming decision was
added to DSLRs later - a tertiary feature - as users asked for more
functionality from the camera, pushing them to be more multifunction devices. .
. As such it is a ‘weaker muscle’ for the device.
Timelapse on Canon 5D cameras are hard on the shutter and mirror mechanisms of
the cameras - the mirror moves for every shot. This is true no matter how
you’ve set the focus, unless you chose to turn on the mirror lock feature in
your camera’s settings menu prior to starting your shoot.
When the mirror sticks and the camera refuses to work with a full battery and
card etc. it may be a mechanical issue between the mirror & shutter related to
wear & tear; it could also be related to the circuit board. Apparently 7,000
images is a threshold mark for physical wear and tear to begin to show up on
the 5D camera bodies and impact the mirror movement / shutter movement
mechanisms.
A tinkerer’s approach - fiddling with taking the lens off and reassembling the
camera, seeing if it will turn on, several times - may encourage the mirror to
drop back into position. Also if you can get the camera to turn on you can
check your menu settings for the ‘mirror lock/unlock’ function & toggle that,
to see if it makes something happen.
If you have warranty support its definitely something to talk to Canon about.
They may recommend a technician local to you or let you know you need to ship
your camera body to them for repair.
