During the last several weeks, I have received several requests from our readers about finding the total number of shutter actuations on their DSLRs. I decided to write a short article on how you can find the total shutter actuations on both Nikon and Canon DSLRs, in case you are interested in seeing how much you have been using your camera or how close your shutter speed is to the manufacturers’ rated shutter life of 150,000 (on most entry and mid-level cameras) or 300,000 (professional cameras).
1) EXIF Data
The information on the total shutter actuations on your camera is preserved in file headers, known as “metadata” or “EXIF”. If you do not know what EXIF is and what it is used for, check out my “What is EXIF” article that I wrote a while ago. Basically, your camera writes all exposure-related information such as date, time, shutter speed, aperture, ISO and a bunch of other important information into the header of each file. Some camera manufacturers like Nikon and Canon also add unique shutter actuations data fields that are used for seeing the total number of exposures or “shutter actuations” cameras have.
2) Switch to JPEG format
If you are shooting RAW, it is best to switch to JPEG format just for getting the required information from your camera. While the camera native RAW format preserves all of the EXIF information that is coming out of the camera, third party conversion software like Adobe Photoshop Lightroom can strip out some of the proprietary EXIF data, including the number of shutter actuations. Therefore, switching to JPEG will allow you to view EXIF data straight, without having to import the image into Lightroom or Photoshop first. It doesn’t matter what size of JPEG files you choose – even JPEG BASIC works fine. Once selected, take a picture of anything you want.
3) Download EXIF viewer
In order to view the proprietary EXIF information from files, you need to use an image EXIF viewer that does not strip out anything from the file. Unfortunately, almost all current image viewers only display generic EXIF data that most people use and ignore the rest. Instead of properly reading EXIF data from files and then parsing the results, they typically just look for generic EXIF tags within the file and display them when they are available. If something is not available, it stays blank. To reduce the number of blank items to the minimum, they only provide generic information that is more or less standardized across most camera manufacturers.
