Canon EOS 5D Mark II shutter count actuation utility

by planetmitch11 Comments

Update: Well there's not really much to update – but this is a older post that continues to have lots of hits, so I thought I'd at least re-post it in case there are those of you who haven't seen it since it was posted in 2009. I have written to the utility's author to see if there's anything new. Would love to find out he's done a mac version since then, but you'd think he'd update the website if he had.

original post (Aug 4, 2009):

There's always been a desire to know the count of exposures/shutter actuations for the Canon EOS 5D Mark II (as well as the original Canon 5D) and now, there is a utility from AstroJargon called EOSInfo that will give you the number of shutter actuations. AstroJargon has updated their earlier tool for the 40D and it now includes all cameras with the DIGIC III/IV processor (“The shutter count information is available *only* on Canon DIGIC III/IV DSLRs *except* the 1D* series.” read the whole page) as well as adding some features. This will be especially good for checking out the number of exposures someone else has had on a camera if they're trying to sell it to you.

From the AstroJargon site:

“EOSInfo is the successor to the 40DShutterCount utility. I called it EOSInfo since it provides more information than just the shutter counter, and works on a wider variety of cameras than just the 40D*.

EOSInfo is for Windows only. At this time, I don't have any plans for creating a Mac version, largely due to time constraints.

EOSInfo improves on the 40DShutterCount utility in a few ways:

  • It is packaged with an installer, so installation/removal is straightforward
  • It is installed with its own copies of the support .dlls from the Canon SDK, so future updates of the EOSUtility from Canon won't hose EOSInfo – additionally, you don't have to install the EOSUtility in order to use this.
  • It provides more information about the camera that might be handy, including firmware version, date/time, and owner/artist/copyright strings.
  • It doesn't matter if your camera is on or connected when you fire up the utility – if you turn it on after you start EOSInfo, the utility will recognize the camera.
  • It will update the shutter count in real time if you shoot tethered (except for the 5DMkII – it still seems to require a power cycle to update the shutter counter value).”

Since I don't do windows, I guess I'll have to ask for someone out there to download it and check it out. Update 2011: I tried downloading the old tool and I get a failure notice – I don't know if you can even download the old mac tool any more. I have written the author.

Read all about it on the astrojargon site!

Thanks as well to @LipsiArt on twitter for the tip!

  1. “The shutter counter will not be displayed (or will be displayed as “0”) on the 1D*, 5D, 10D, 20D, 30D, 300D, 350D, and 400D.”

  2. It doesn’t work on my Canon 7D….Any suggestions???

    Thank you very much

  3. Thanks, having problems with my 5D MK II – focusing and canon sent me a refurbished one with (now i know) 1,021 actuations. Thanks great utility. Now if I could just get the 5D MK II to focus consistently, I would be in camera heaven!

  4. It don´t work with my 550d. I have no clue. EOS info told me :No camera connected. what´s the reason?

  5. To read the Canon 5DMkII shutter count. You have to power-cycle the 5DMkII before the shutter count value updates itself.

  6. I seriously doubt the results are accurate.
    I know for sure I reseted the counter on my 5d2 several times, probably more than 10 times which means I took over 100,000 photos in 3 years. In fact I’m looking right now at 7 different photos with the same file name (i.e at least 7 cycles)
    Without any card inside, the utility reports less than 29,000 actuations.

  7. It didn’t work on my 5Dii, it showed a count of less than 3,000, whilst I am up to image 7, 540 on continuous numbering of my images.
