even advanced photographers use only small potential of any modern camera or lens
an excellent examples of that are many posts by Brian (blw) about non common used of lenses to fulfill your needs.
Take a look at the gallery of coolmom42 (she posted several time in this thread). I remember couple of years ago she had only D3100 and 18-55 and 55-200 combo. It never stopped her from creating some stunning images).
another example was my posting above where I took a challenge and used only 35mm prime - i had to put on my thinking cap and do some leg work but it was a good chellenge.
18-55mm lens is as good as it gets among any kit lenses. Most people just want to cover greater range with one lens and buying 18-105 or 18-200/300 lenses.
My point here is if money is an issue and you do not mind to do some leg work to get closer to your subject – then 18-55 is a great first lens to learn photography and most important to become more creative and less “couch-potato” photographer. Settle on something and start taking pictures. In 3 months you either get a second job to support your NAS or your dSLR camera will be collecting dust someplace.....
