sensor cleaning on D5000
Those with IPhone's can download an app that checks your hearing. Very interesting. I used to hear some ranges that only kids/dogs could hear but as of the last couple years that has gone. A co-worker will occasionally test me without my knowledge. Very annoying sound so if you hear it, you know it.
How do you work this crazy thing?
