For the people who are familiar with both cameras. Which is the better camera in your opinion? I am looking for a used camera and I came across a D50, but dont know much about them, and didnt even know they existed. If I am not mistaken, the D50 is the pricier camera, right? I loved the D40 I used to have, so I am a little uneasy about getting a different model. But with what I've read about the D50, I think I'm gonna go for it.
