Right now I have a Nikon Prime lens but I miss a ton of great shots because I have zero zoom. I really don't know what I want besides having a zoom and really don't know too much about pros and cons to lens. I have no idea why some lens are 1000 bucks while others are under 200.00. From my understanding the more zoom you have, the more glass is in the lens and the less crisp the pictures will be? If you guys could just point me in the right direction.
