what Camera/lens should I buy

One of the first questions asked by beginners is, what lens should I buy?

The answer naturally depends on your needs. Here are some things to consider:
What is your budget?
Do you have a specific need?

Did you buy your camera with a certain purpose in mind? There’s no point in buying a long telephoto if you’re mainly interested in photographing stamps, for example.
What focal length range do you use the most? One of the great things about digital cameras is that they record shooting data for each picture. You can then use an image cataloging program to sort photos by focal length, aperture, and so on. If you find yourself using a certain range a lot, maybe it’s worth investing in a high-quality lens that covers that range.
Conversely, what do you find yourself missing? When you take shots, do you always end up at the wide end of the lens, wishing you could go wider? Or do you find yourself at the long end, longing to be able to reach further? Think about what’s wanting in your best shots.
