  • Item

    Dioptric

    They use a lens that refracts light and focuses it at the back end.
  • Lens Diameter 108 mm

  • Focal Length

    It is the distance that light rays need to travel to reach the focal point, that is, the sensor of the lens.

    The shorter the focal length, the wider the angle of view for the photograph, and therefore, the more of what is in front of us the lens can capture.
