I'm looking at purchasing a D300. I currently use a D50. I was told that my D50 lenses would not work on a D300 because of how the camera and the lense work together. I was told that the D50 lense focuses using a motor inside the lense and the D300 uses a motor inside the camera body.
Something here doesn't sound right.
What is the real story and where would I find the information?
