What's you advice guys?

I'm gonna buy my first dslr camera, i don't know much about photography and i'm 18.so i've decided to buy the nikon d5100 should i get the kit lens or anything else? What are 18-55 lens for? I just want the dslr for family and friends moments.

Just get the 18-55 for now. Be sure to buy a genuine Nikon spare battery, a couple 8GB Class 10SD cards, an SD card reader ($8) and a little camera bag. A basic photography book wouldn't be a bad investment.

Buy the D5100 with the standard 18-55mm zoom. Manufacturers have determined that the 18-55mm focal length range is sufficient for about 95% of the photography you'll be doing. They're hoping, of course, that the 5% you can't easily do with the 18-55mm zoom will lead you to buying additional lenses - which is where they really make their money.
I suggest adding a good quality UV filter to protect the front element of your lens. Choose a "thin" or "slim" mount filter from Tiffen, Hoya, B+W or Heliopan. Always remember this: "A cheap filter isn't good and a good filter isn't cheap." I recommend a "thin" or "slim" mount filter to avoid any possibility of vignetting (dark corners on your pictures) at 18mm.
You might also want to consider adding a good tripod to your kit. It will allow you to get in the picture yourself should you want to. Take a look at the Benro Travel Angel series of tripods.

A good place to buy your D5100 and your filters and tripod is B&H.

Read this:
http://www.luminous-landscape.com/columns/aesthetics-1.shtml This deals with the rather esoteric concept called "seeing photographically". Many people may look at a scene but a photographer will see the picture that is contained within the scene. There really is a difference between "looking" and "seeing" so you need to understand this concept.

It's probably only sold with the kit lens and not body only. The 18-55mm is a good one to start with. Then you may want to add on the 55-200mm.

Get the kit lens and then later on you can get more lenses. You can shoot most anything with the kit lens. Like someone else said, get a spare battery, card and card reader. A camera bag is a must as well. I would look at the 50mm f1.4 as your next lens. Enjoy

Just go with the kit lens initially if you grow out of this lens than can buy another.

There's some thourough information, but your answer hasn't been answered yet. Simply put, the 18-55mm kit lens is quite good and you would use it for landscapes, portraits, a little bokeh photography. You should start with this if you can afford one lens. The 55-200mm option is also a good lens you might want after you get a wider angle like the 18-55mm. It's a normal-telephoto lens good for sports, concerts, wildlife.
