Under Camera Settings, which can be accessed by double-clicking on the camera layer, there is a dropdown box under Preset. These presets are focal lengths.

The focal length for this camera view is 15mm.
Here is the opposite extreme of 200mm.
Here we can adjust the amount of the image seen by the camera. In the Camera Settings, set Zoom to 140.
Change the Angle of View to 100. Try different settings to change the angle.
If you check Enable Depth of Field, you can then apply different types of blur to the piece. Anything outside the distance range becomes blurred.
The Focal Length is the distance from the film plane to the camera lens. If you change the Focal Length, the Zoom properties also change and vice versa. If I change the Focal Length to 200, notice how close the image is to the camera lens.
If you change the Focus Distance, this represents the amount of distance from the camera's actual location to the plane which is in perfect focus.
To adjust lens opening size and F-stop setting, check Enable Depth of Field and unselect Lock to Zoom. The larger the opening setting is set to, then the higher the depth of the blur field will be.
Finally, the Units in pixels represents a film size in comparison to the comp size in pixels. If you set the film size to i.e. 35mm, then that would represent 102.05 pixels horizontally, or 76.535 vertically, or 127.56 diagonally respectively. Reducing the film to a smaller size makes the view zoom larger. Units can be in pixels, inches, or millimeters.
