Finding Your Camera’s Current Shutter Actuations or Shutter Counts..

http://www.olegkikin.com/shutterlife/sitemap.php - features the shutter life expectancy for numerous models from all the different brands.

Canon Cameras

It’s necessary to note that Canon doesn’t store the shutter actuation details in the EXIF data. So for Canon, things are a little different; the best program to check your shutter count is EOS Info.

EOS Info is a neat little program by AstroJargon. It’s freeware, although they do ask for donations if you can spare it. It will provide the shutter count, the serial number, the camera model, the firmware version as well as the owner and date the results as well. EOSInfo works with almost any DSLR, excepting the 500D (may/may not work; their website says not, but it’s worth giving it a shot anyway). How does it work? Simply connect the camera to your computer using a cable, run the program and – voila! Your details are there for your examinations. Prepare to be surprised, though, as sometimes it’s more than you think! It’s not available for Macs, though, only for PC’s; however, EOSInfo is the updated version of the 40D Shutter Count a previous edition, which – despite the name – works on almost any DIGIC III/IV DSLRs, excepting the 1D series. It runs on Macs, using a cable as like EOS Info.
Nikon and Pentax Cameras

Nikon and Pentax store the shutter count details in the EXIF data. For Nikon and Pentax, you can either use My Shutter Count - simply upload a JPG or RAW and get your results – or download Opanda IExif . Note: IExif should work with Pentax; this has not been tested/. However, if it doesn’t, you can still use My Shutter Count to get your shutter count.
Olympus Cameras

Olympus doesn’t store the shutter acutation details in the EXIF, but conveniently, there’s a nice trick one can use for Olympus bodies. Simply follow these instructions:

1. Turn your camera on
2. Open your memory card door
3. Press “PLAY” +”OK” at the same time
4. Press on the dial, in order: up, down, left and then right
5. Depress the shutter release button fully
6. Press up on the dial
