Focal Length - 

Definitions: 

• Focal Length: The distance between the centre of a lens and its subject. 
• Field of View (FOV): What can be seen. (Determined by angle of view from the lens to the scene (Horizontally and or vertically). 
• Wide Angle: A lens with a short focal length than standard and this provides a wide field of view.  
• Standard Lens: A lens with a focal length of 50mm is considered normal; they work without reducing or magnifying the images; reflect the way we see with the naked eye (Angle of 46 degrees). 
• Prime Lens: Fixed focal length which does not change (Higher quality).
• Zoom Lens: Allows the user to alter the focal length (More versatile).
• Telephoto Lens: A lens with a larger focal length than a standard; provides a narrow field of view with a magnified image.
