🔵 WHAT IS A FISHEYE LENS?
A fisheye lens is an ultra wide-angle lens that captures a very wide field of view — up to 180° or more — creating images that appear curved or spherical, like looking through a fishbowl. That’s where it gets its name: “fisheye.”
🧠 QUICK DEFINITION:
A fisheye lens is a special camera lens that distorts straight lines and gives a rounded, bubble-like image, allowing it to capture an extremely wide view.
🎥 KEY FEATURES:
| Feature | Details |
|---|---|
| Field of View | Up to 180° or more |
| Image Shape | Curved, circular, or bulging |
| Distortion | High (lines curve outward near the edges) |
| Lens Type | Usually short focal length (8mm to 16mm) |
| Effect | Makes spaces look round, surreal, or fun |
📸 TYPES OF FISHEYE LENSES:
-
Circular Fisheye
-
Produces a circle-shaped image inside a black frame
-
Covers a full 180° in all directions
-
-
Full-frame Fisheye
-
Covers the whole image sensor — no black borders
-
Slightly less than 180° coverage but still ultra-wide
-
🔍 WHAT DOES A FISHEYE PHOTO LOOK LIKE?
-
Buildings curve outward
-
Horizons bend
-
Looks like a bubble-shaped window into the scene
-
Fun, artistic, or immersive feel
🎯 WHAT IS IT USED FOR?
| Field | Use Example |
|---|---|
| 🎞️ Photography | Creative shots, landscapes, architecture |
| 🎮 VR / 360° | Used in 360-degree and VR camera systems |
| 🚗 Car Cameras | Backup or surround-view cameras in vehicles |
| 🧪 Science | Astronomy, meteor tracking, microscopy |
| 🏠 Security | Wide coverage in a single camera |
🔁 DIFFERENCE FROM NORMAL WIDE-ANGLE LENS:
| Feature | Wide-Angle Lens | Fisheye Lens |
|---|---|---|
| Field of View | 60°–100° | 120°–180°+ |
| Distortion | Minimal or corrected | Deliberate & dramatic |
| Lines | Mostly straight | Curved & bent |
🧠 FINAL THOUGHT:
A fisheye lens is like a magic eye that sees the world all at once —
not flat, but in a wild, curved panorama of reality.
Fun, useful, and essential for 360° capture and creative imaging.
