EXIF Viewer/Shutter Life Expectancy
I stopped posting EXIF data a while back because I got annoyed that the built-in info viewer for my Mac didn’t show ISO. I ran across one that does and downloaded it, so I may start posting the information again. The program is free for download (for Mac) at http://homepage.mac.com/aozer/EV/ if you’re interested.
It also shows the number of shots you have taken with your camera (actuations) which is useful if you want to know how much life your shutter has left in it. I think most DSLRS are good for about 100,000 shots. I’m up to 16,000+ on my D90 and 17,000+ on my D50. You can look up the life expectancy for your specific camera here: http://www.olegkikin.com/shutterlife/. Update: Digital Photography School just did an article with info on how to find actuations for different brands of cameras.
