After spending ½ a day researching and trying to find the shutter actuations for my Canon 7d and Canon 5d Mark iii DSLRs, I decided to write a blog post about what I learned. I searched dozens of message boards, read blogs, downloaded software, uploaded photos to websites, and played in the Mac terminal program.
- Unlike Nikon, Canon does not expose the number of shutter actuations in the camera EXIF data. So, using Show Inspector (Control I) in Mac preview does no good. The File Info selection in the File Menu in Photoshop has a lot of good information, but not the shutter actuations. Uploading an image file to websites such as MyShutterCount.com also doesn’t work. The data just isn’t there.
- In order to get the shutter count on Canon DSLRs, the camera needs to be connected to your computer through the computer's USB port. Your Canon DSLR should have come with USB to mini USB cable to connect to your computer. I started my search for software and websites that could read the shutter actuations off of the camera.
- I downloaded a Mac program called 40DShutterCount. That didn’t work for my Canon 5d Mark iii or 7d.
- There is a more recent version of this program called EOSInfo from astrojargon.net that is available for Windows only. This also didn’t work for my Canon 7d or Canon 5d Mark iii. I got a “No Camera Found” error.
- EOScount.com installs an ActiveX control on your computer. It only works with Internet Explorer on a Windows Machine. Well, this service is no longer free. They now want a $1.59 to read your camera and tell you the number of shutter actuations. I’m not sure if it will work either. It displayed the serial number for my Canon 5d Mark iii as 5. I know I bought it early, but not that early.
