Nikon Lens Review: The most important part of the camera.

Most likely your camera came with a lens. If you bought the body only, chances are you already have a lens, or you know what you are doing.

Cameras most often come with a kit lens. The kit lenses are surprisingly good. If it was made by Nikon or Canon, it is not junk.
Typically, a kit lens is sort of a Jack of all trades, but master of none. At the time of this article, one of the most common lenses going with a kit is the 18-55mm. You're in luck, this is a great lens. It does wide angle well, and also zooms to give you a moderately "normal" view.
This is where everyone thinks, yea but I want to ZOOM. What you actually probably mean is I want a telephoto. Zoom just means the lens changes magnification, telephoto means that it magnifies to a fairly large degree. Typically telephoto begins in the 100mm+ range.

Nikon has a great answer to this, with a very good zoom lens for a bargain price. The 55-200mm VR lens. VR stands for vibration reduction, and it is a great feature to have.
Now with this lens you can cover 18-55, and 55-200. In essence with one lens change you are set up for 18-200mm. This is all you will really ever need for most applications. If you want to take photos of things that are hard to get close to, or even hazardous, you might need some more equipment. What do you mean this is all I need?
It is. You can take stunning photos of a whole lot of things, impressing not only your family and friends, but everyone else as well.
If that is the case, why do I see all kinds of other more expensive lenses about?
Well, they do things slightly better, make it slightly easier, or are more specialized. Once you start taking more and more photos, you are going to most likely find a niche, or settle on something you like to take photos of. Be it birds or bugs, buildings or the moon you will be able to find lenses that will help you do that.
