Original post (Aug 4, 2009): There's always been a desire to know the count of exposures/shutter actuations for the (as well as the original Canon 5D) and now, there is a that will give you the number of shutter actuations. Has updated their earlier tool for the 40D and it now includes all cameras with the DIGIC III/IV processor (“The information is available *only* on Canon DIGIC III/IV DSLRs *except* the 1D* series.” ) 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 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*. Canon Printer 3000 Repair Manual here.

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 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. 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.!
