The focal length is the distance between your camera’s sensor and the optical center of the camera lens.
If you have a longer focal length, the overall perspective will be reduced, the subject will be closer, and areas won’t be as clear. The opposite is true for a shorter focal length. It will give a wider perspective and overall be more focused.
