Fisheye lens

Definition

A fisheye lens is a specialized ultra-wide-angle lens that creates a distinct visual distortion by capturing a 180-degree field of view or more. This type of lens is characterized by its ability to exaggerate perspective and provide a unique, circular image effect, making it popular for creative and artistic photography as well as wide panoramic shots. Fisheye lenses allow for unconventional framing and composition, which can enhance storytelling in visual media.
