I owned a D40 just in a while well it's because it wasn't mine. To tell you, A D40 isn't that bad. It's really for built for people beginners. One thing that is good about the D40 is, it's easy to bring. It's small and lightweight and has a better battery duration taking up to 470 shots. One thing I can't share to you is that i never had a bad experience with this camera since I only had the chance to borrow it for 1 week.
I first had a Fuji Finpix but purchased the D40 at the beginning of the summer. For me being an amature it is perfect. The close up shots are amazing. I will graduate to another model latter.
i have nothing but great things to say about this. I am also ready to upgrade.but I mean awesome photos..I upgraded to a close up lens and the shots i take with this d40 is amazing. love it
