In short, it depends on the lens. For example, Canon typically includes an 18-55mm lens with their DSLR cameras, but it's not always the best quality lens, and there a LOT of factors to consider when you're looking to upgrade. The price of the lens has a lot to do with the quality of the glass (which effects how much light travels through it), what sort of features the lens has (image stabilization, auto focus, etc.), and of course, if it zooms and how much it zooms to.
While an 18-135mm lens might seem like a logical choice, these lenses usually have a high amount of distortion at the longer focal distances. If the lens is rated with a high F-stop you will need to keep the camera steady and keep the shutter open for a long time just to have the images come out less blurry (your chances of zero blur are pretty slim), and if you're trying to capture moving subjects like people or animals, well... forget about it. With a low quality lens at 135mm, your images will most likely come out blurry, with lots of "noise" (artifacts in the image due to the camera increasing the capture speed to compensate for less light), and (in my experience) a weird purple sheen.
That's not to say that there aren't professional 135mm lenses out there that will do the job, but I am assuming that you're not considering shelling out $5000-$10,000 for a lens quite yet (if you are, more power to you). If you don't want to shell out that kind of cash, I recommend buying the 18-55mm to start, and later supplementing it with an affordable fixed (not a "zoom") long-focus lens with a low F-stop rating.
