The zoom on my camera

I have been wondering what the differnce in my is with my lens. The smaller one has a zoom from 18 to 55. While I was at the park taking pictures I picked out a tree and took a picture at the lowest and highest setting of each lens. It's kind of small in this first picture, so I drew a red circle around it (look in the center).

The with the same lens zoomed into 55.
Then I switched lens. This lens starts at 55 (that's why the pictures look the same.)
This last picture was at 200.

I am so happy with my new camera!
