Here's how: 1  Stand with your feet shoulder-width apart and knees bent slightly. 2  Lean forward, placing your hands just above your knees. 3  Round your back so that your chest is closed and your shoulders are curved forward.  Then arch your back so that your chest opens and your shoulders roll 1  back. Repeat several times.
Typically this count is between 100,000 and 300,000 shutter actuations, with the latter limit associated with the EOS-1D models. In fact, the Camera Shutter Life Expectancy Database is a really neat user-based site for DSLR models of several brands, including Canon.
1D Mark IV Shutter Count. I ordered an open box camera and I am curious about the number of shutter actuations to get some idea how much the camera may have been used.oes anyone know of a way to determine this on a 1D Mark IV? I did a search and it appears that the most recent reply to a similar question is 18 months old and it applied to compact cameras not the 1D series.
