The lens that comes with the Nikon D5000 when you buy it with the "kit" is an 18-55mm lens, otherwise known as the 18-55mm f/3.5-5.6G VR AF-S DX Nikkor Lens. When I bought my first DSLR, I had know idea about lenses, I didn't even know what 18-55mm meant. However, over the next year I used and loved this lens. I didn't purchase a second lens until a year later once I had the basics of DSLR photography figured out. Really, it was a great lens to learn photography with. I took lots of great photos with it and really enjoyed using it. Also, it is really small compared to the lenses I use now which is a huge advantage. I don't use it very much anymore because I have a Nikon 18-200mm lens which as the number imply, does what the 18-55mm does plus more. That being said, even though I don't use it much any more, I have no complaints about this lens and definilty got my moneys worth out of it.
