(Update 2013-11-23 – this first bit is a bit old — notice the update about ShutterCount below) – You cannot find the true actuation count without sending the body to Canon, however AstroJargon’s 40D shutter count does a very good job of getting close – you just don’t get a count of any actuations made in LiveView.

Note that if you have a Canon camera and are willing to install it, Magic Lantern version 2.3 has a shutter count function in it! See our review of Magic Lantern.

Update 2013-11-09: There’s now a new utility for the mac called ShutterCount that will give you accurate shutter counts (actuations)… see this new planet5D blog post

Mac App Store - ShutterCount   App Store

Other cameras?

I don’t have a clue at this point about other cameras… do you guys know if Nikon or Panasonic etc. have a shutter count?

Mitch "planetMitch" Aunger is the creator and mastermind behind planet5D.com — which covers every aspect of HDSLR cameras (and a whole lot of other cameras as well). A lover of photography since his early days, he graduated to selling stock photos to make a little bit of spare cash. It wasn’t much, but it allowed him to upgrade to better cameras as well as computers, and it wasn’t taking money away from feeding his family.
He loves the stories that the still image can tell. In the summer of 2008, he read a story written by Arnold Kim called “I Quit My Job” — Arn is the owner of macrumors.com. He started macrumors in 2000 as a hobby, and by 2008 he was making more money with the site than he was on his day job, so he quit. The surprise to the story is that he was a doctor making more than six figures! Right then and there, planetMitch dreamed about doing the same thing.
September 2008 rolled around, and Canon announced this new version of the incredible 5D — the Canon EOS 5D Mark II. It was the first Canon DSLR to shoot full HD video and the earth moved! (It really was a huge deal in the photography world.) planetMitch knew if there was ever a chance to ride a wave of something he was really passionate about, this was it — and the blog at planet5D.com was born. It is now one of the most popular HDSLR blogs on the planet, and he is making a full-time living from blogging. He couldn’t be happier!
