fisheye lens
A fisheye lens is a type of ultra-wide-angle lens that captures a wide field of view, typically around 180 degrees or more. This lens creates a distinctive, spherical distortion, making straight lines appear curved, especially near the edges of the image. Fisheye lenses are commonly used in photography and videography to create dramatic effects or to capture expansive scenes in a compact format.
These lenses are popular in various fields, including landscape photography, architecture, and sports photography. They can also be used creatively in artistic photography to produce unique visual perspectives. Fisheye lenses come in both circular and full-frame formats, each offering different aesthetic results.
