What's new in Shutter Counter
This application can't support new Canon Cameras, such as Canon 5DS, 5DSR, 5D Mark IV... etc. The main reason is - Canon always return "1" as Shutter Counter value. I don't know why. I hope, canon will fix it soon. Right now, you can use application only for old cameras. For new cameras, you can check Serial Number of device with Body number. And, if it set, owner name.
