There are two ways to zoom.

1) Move the camera closer.
2) Use the zoom tools.

Moving the camera changes the front clipping plane, much the same as in real life if you walk closer to a subject to take the picture.

The zoom tools just make everything bigger, much the same as blowing up and cropping a picture but also increases the resolution. The front clipping plane won't change in this case.
