Hi, everyone! Konstantin, the developer of ShutterCheck here! Nowadays a lot of people are engaged in digital photography. Some are satisfied with the capabilities of theirs iPhone camera, but those who want to go further buy themselves a full-featured DSLR cameras like Canon EOS series. The modern DSLR camera is a complex and expensive device that costs a couple of thousands dollars, take the EOS 5D Mark IV for example. Some people who can’t afford to purchase a new item choose to buy a previously owned camera. If you are familiar with digital photography you may know that today’s DSLR cameras still feature a mechanical shutter in front of a sensor. Every time you take a photo shutter blades are actuated to control the exposure of your image. Modern cameras have shutter mechanisms that are rated for something about 100,000-400,000 actuations (the actual value depends on camera class: entry-level or professional). That’s called a shutter rated lifespan and it stands for a number of guaranteed ‘clicks’ that you can make with your camera until the shutter wears out and replacement would be needed. If you buy a secondhand camera you should probably want to know its shutter count because it’s like a mileage of a used car! But it turns out, there is no way to check shutter count of a Canon EOS camera except maybe taking it to a service center for a diagnostic. I’ve spent five months reverse-engineering Canon EOS cameras and made ShutterCheck app that is now capable of reading shutter actuations count from 65 Canon EOS models, including the recent additions to the lineup, such as EOS 1D X Mark II, 5D Mark IV, 5DS and 6D Mark II. For newer devices an extended shutter information is also available: besides plain shutter count you’ll get separate values for photos taken through the viewfinder, photos taken via the Live View and a number of Live View sessions. ShutterCheck displays shutter count along with a shutter’s rated lifespan so you can easily see the percent of its wear. I believe ShutterCheck would be a great helper when making deals on preowned cameras because it allows you to easily estimate/verify value of a previously used item in order to make quick and hassle-free business. During the launch the app is available for a reduced price of $2.99. Let me know what you think about my product. Thanks!
