Best lens deals?
For a skilled photographer, even the 18-55mm IS can do a amazing job. It is not a tough lens construction wise, but stop it down a couple of stops, and expect excellent results. For $100 more than just the body, its a great deal.
In fact, almost any lens will do a excellent job in the hands of someone who knows how to get the best out of it.
Buy for the focal length and aperture you need as first priority, don't buy a focal length you do not use just because its a good lens.
