Wide-angle is a term used either to describe a type of lens ‘wide-angle lens’ with a focal length of generally shorter than 30mm which gives a wide field of view due to its optical properties, or alternatively is a term used more generally to describe a shot that encompasses a large field of view ‘wide-angle shot’

a lens of short focal length that affects the scene's perspective by distorting straight lines near the edges of the frame and by exaggerating the distance between foreground and background planes. In 35mm filming, a wide-angle lens is 30mm or less. Produces the opposite effect of telephoto lens.
