What are the focal lengths, types of lenses, and characteristics of each?

Focal length reflects the change in the angle of view.

Generally , they are divided into...

  • Fisheye: 180-degree viewing angle
  • A super-wide angle, lower than 24mm, but in recent years many people have set this scale to 16mm, thinking that 16mm is not considered super wide. Currently, the shortest non-fisheye wide ones are generally 11 or 12mm.
  • Wide angle, 24-35mm, there is also a range of 16-35mm.
  • Standard lens, approx. 50mm
  • A medium focus, 70-135, is generally considered medium focus, and some people consider 85 and above as telephoto.
  • 135-300 It is generally considered to be a telephoto lens.

Super telephoto, no more than 300. Nowadays, everyone is greedy and thinks 400 or more is considered a super telephoto. Super telephoto lenses for civilian use are typically 600mm or 800mm, which are essentially fixed focal lengths, and zooms are particularly heavy. Typically, 1200mm is the limit, and if it is longer, it is rarely used by civilians.
The key difference between different focal lengths is the angle of view. This difference in viewing angle will result in changes in the sense of spatial compression.        

At Yuntai Optics, panoramic lenses are widely developed and produced for use in the automotive and security industries. Today, we will primarily focus on practical cases used in vehicles.
