I am trying to decide what lens to buy for my Canon EOS 350D. The first descision to make is what focal length I need. To do this, I found a nice tool which can display statistical info about your photographs. It shows you how many foto’s you’ve made at certain focal lengths, with which aperture, ISO, metering, and other EXIF fields. It’s a windows only tool, and it’s called Smart Photo Statistics. It’s absolutely 100% free software and works as expected. It can even copy the graphs to the clipboard for you to use elsewhere.
I’m gathering statistics right now on all photo’s of all digital camera’s I’ve owned, to see what focal lentgths I need. Great tool!
