The 35mm was too narrow for DX, but perfect for FX for me. That's why I was thinking the 24mm would be good. It is small and light. I used to hand my D7000 to my daughter with the 35mm on it and tell her to take photos of her brother. The results were very good. I've let her play with cameras since she was about 3 years old though. A kid with a pocket camera can be quite amusing. Lots of laughs when you go later and look what is on the card.
There was a second-hand 14-24 in the camera store the other week. VERY tempting. It is such a mad lens. I enjoy how it makes everything you stick it right up to look more interesting by overblowing the depth and size of objects, but with tons of detail.
I can assure you that this stone creature was not at all interesting at a distance.
I have a ton of pictures of my kids and friends' kids taken with it shoved in their face more or less. Way more fun than the usual flat, generic shots of them doing stuff. The downside is: Portrait shots do not work. It is landscape or nothing. It gets tiring after a while though, as everything is crazy, all the time. That's another reason for the 16-35 choice: I can have normal or crazy without having to change lenses.
