I got a AF-S DX NIKKOR 35mm f/1.8G, which is a single focal length lens. With D90, it will be a lightweight camera system. For Nikon DX format, the 35mm focal length means normal length lens, because effective focal length will be 52.5mm (35mm x 1.5 times).

Below is a photo sample near Kawasaki station. This building is “Muza Kawasaki“, a symphony hall. With a wide diameter as f/1.8, I could take a picture at night scene.
