This saturday I am going to buy a Nikon D40 (at last!!), and I am curious about which lenses to buy. I am a total beginner, and even tho I already inscribed in some classes to learn the basics, I know that here in MacRumors there are very good people rspecting to photography and I guess I could use the help. What I like the most is to take photos of Nature and City Landscapes. I know the included lens with the D40 is a good one, but I'll like to get another one in the near future. - I was thinking along the lines of a good zoom lens, or something good to take close-ups. My budget is around $500, but something cheaper would be better. - Also, which good tutorial would you recommend to learn more about lenses? Thanks for the help, I know I have been asking so much lately, but I guess it is the excitement of at last buying a dSLR.
