ShutterCount Supports New Canons and More

Shutter count for new Canons

When you spend years on reverse engineering Canon cameras, you are bound to see things… Know things that only a few knows. Things that most people wouldn’t believe. As my better half used to joke: I know more about Canons than what would be healthy… On the other hand this knowledge paves the way for neat things.

Almost exactly two years ago, when I added support to our apps for the 5DS R, I had to realize that Canon did something to the camera’s shutter counter. That something rendered the way ShutterCount used to query the counter useless. We immediately started a research side project to determine what’s going on and to find a way around.

Since I wasn’t comfortable navigating uncharted waters with my 5DS R (and later 1D X II), we bought three 1200Ds for the purpose. So let me introduce the Suicide Squad – these cameras contributed a great deal in bringing you ShutterCount 3.

Cameras in the Suicide Squad (a.k.a. “The Kamikaze”) were ready to sacrifice their lives for the project. All three cameras survived with no damage at all.

It took two years, but I can proudly tell you that all those sleepless nights and hard work weren’t for nothing: not only we can read the shutter counter on all new Canon EOS DSLRs, but ShutterCount 3.0 does something never seen and done before.

Let me show you the camera summary screen in its full glory first. I mean including all the information the app is capable of displaying (total number of shutter actuations including live view related ones, plus the percentage where the camera’s shutter stands relative to its rated number of actuations).

My 5DS R’s info shown in ShutterCount 3.0. Both the Live View Pack (to show live view related actuations) and the Plus Pack (for the shutter rating percentage) are active.

That’s fine, but the app goes further than this. The new Distribution Chart shows a detailed breakdown of shutter actuation sources (you can also hover the cursor over the shutter count value on the summary screen for a textual breakdown).

The Distribution Chart showing the three different shutter actuation sources.

Cameras with electronic first curtain shutter (basically all Canons released after 2014, with the exception of the 1300D) are capable of providing separate numbers for photos taken through the viewfinder, for photos taken while in live view and for live view sessions. A live view session starts when you engage live view and stops when live view is turned off. Movies are part of the session number (no matter how many clips you record during a session it will count as one since the shutter only opens and closes once).

This detailed breakdown is a world’s first.

Older cameras behave a little differently. They only provide two counters: one for photos, and another one for all live view actuations.

The Distribution Chart for non-EFCS cameras (my 7D Mark II in particular).

Live view on non-EFCS cameras has a great impact on the shutter. When you take a shot in live view, the following happens:

  • The shutter opens when you start live view.
  • The shutter closes immediately before you take the picture, since the mechanical first curtain must be used.
  • The shutter opens and closes for the shot itself.
  • The shutter opens again after the shot has been taken to re-enter live view.
  • The shutter closes when you stop live view.

That is, a single shot in live view generates two shutter actuations for the shot, plus one for the session. One of these is counted in the “photos” number, the extra two in the “live view actuations” number. Took two shots in a session? The shutter was actuated 2 + 2 + 1 = 5 times. 2 of these is counted in “photos”, 3 in “live view actuations”. And so on. Movie recording is simpler – the shutter only opens at the beginning of the session and closes at the end, so “live view actuations” increases by one for each session.

Which means that it is really important to know the number of live view related actuations, since it can contribute a lot the shutter’s wear. It may make a huge difference to the camera’s selling price. But at least you can get a more precise picture.

Speaking of precision. I’ve seen things… And my opinion is that the cameras’ internal counters are precise at the scale of hundreds  (that is, 4200 or 4300 or 4400 shots is a difference, but 4210 and 4212 may not be). Unfortunately I can’t publicly discuss the exact details on why, so you need to take my word on it. And don’t stress about less than 100 differences. In one point I was even considering to show the counters only in increments of 100 – Canon does this in increments of 1000 in the 1D X II for this reason. In practice it doesn’t really matter if your camera has 51890 or 51906 shutter actuations, but it does matter whether it’s 51800 or 68900.

File Mode for Nikon and Pentax (and some old 1D models)

ShutterCount 3.0 for the Mac also introduces the File Mode. As the name implies, it uses image files taken with the camera to determine the shutter count – for cameras that actually record the number in the files. It was requested by lots of Nikon and older 1D(s) II/III users, so we added it.

File Mode is a largish topic in itself, so I’ll dedicate a separate post for it during the next days.

Pricing and availability

ShutterCount 3.0 is available on macOS and iOS, and supports all new Canon cameras (released after 2014) in the base app price. The Mac version also supports File Mode. The Windows version planned to be updated later this year with new Canon camera support. Version 3.0 is a free update for existing users. New users can purchase it in the respective App Store for $2.99 / €3.49. For the complete list of certified cameras please refer to the Tech Specs page.

I must repeat, since some people doesn’t care to pay attention: NO WINDOWS VERSION YET FOR THE NEW CAMERAS. Regardless of how hard some wish. Did I mention to read the Tech Specs? macOS only means that the camera is NOT supported yet on Windows.

We tested and certified the app with all the cameras on the Tech Specs page. In other words, we are completely sure that it works. But please, pretty please, check the supported camera list before purchasing.

Live view counters and the Distribution Chart are available when the optional Live View Pack add-on is purchased. For the list of supported cameras please refer to the app’s Tech Specs page. The Live View Pack is available on macOS and iOS for $2.99 / €3.49. On a Mac, click the ShutterCount > Store menu item, on an iPhone or iPad tap More on the tab bar and tap Store in the menu.
