There a a number of software options if they work, people have reported mixed results. There were a few questions just like this on our forms recently if you search around. http://www.freeshuttercount.com/ is one, shuttercheck is a app you can buy https://www.camerashuttercount.com/ allows you to upload an image Please research any options and see how that solution has worked for others with your camera and that software and your operating system before buying anything that is not a free option. Also I am skeptical as to accuracy so you may want to cross reference more than one solution. Canon was never concerned with providing this spec, 3rd parties have devised ways to extract this.
