EOS Inspector

Get shutter actuations count of your Canon EOS camera

EOS Inspector displays a shutter actuations count of your Canon EOS camera, so you can easily check whether a newly purchased camera is really brand new, or how heavily used a secondhand item is. You can avoid a visit to a service center by doing the diagnostic yourself.

Shutter Actuations Info

EOS Inspector displays a shutter actuations count along with a shutter’s rated lifespan (that varies from camera to camera) so you can easily see the percent of its wear. For modern EOS cameras Live View related actuations are also displayed.

For newer cameras you’ll get even more! Most EOS cameras released since 2015 (such as the 1D X Mark II, 5D Mark IV and 5DS) provide more details on shutter’s usage. You’ll get separate values for photos taken through the viewfinder, photos taken via the Live View and a number of Live View sessions. All these values are presented visually on the detalization bar.

Customisation of User Fields

Depending on a concrete model, Canon EOS cameras support up to three user-customizable fields that are used to populate metadata of your photos. EOS Inspector gives you a convenient way to change owner, author and copyright settings of your camera.

Customer Reviews


Does Exactly As It Says With a Beautifully Minimal Design

“Any time you want to buy or sell a camera online, knowing how many times the shutter has fired is a mandatory piece of information. This app does that fast and presents the information in nicely designed screen. I appreciate the care the developer took to show the camera data in a clean concise way. It worked perfectly on my Canon 60D.”

Customer review from the Mac App Store


“Downloaded the app, plugged in my camera, launched the app and checked shutter actuations for my Canon 5D Mark III in less than a minute. Nothing else in life is so easy. Thanks, Konstantin!”

No-Nonsense App that Does What it Says

“This app does one thing and does it very well: tell you how many shutter actuations that a given Canon DSLR has. It’s a great way to measure the “mileage” of a camera. And it’s a nice tool if you want to prove the shutter count when selling a camera. It’s very silly that Canon doesn’t give users a way to see how many clicks are on a camera, and this app solves that silly problem. Well done!”
