Typical characteristics of fisheye lenses
- Extreme angle of view (at least 180° diagonally);
- Circular types (the image circle of the lens is inscribed in the image frame) or diagonal types (cover the entire image frame);
- Usually of equidistant projection type, with the distance from the picture center to any given point always proportional to the angle from the optical axis to that point;
- Huge barrel distortion;
- Short closest focusing distance (0.20 - 0.30m with 35mm full-frame prime lenses);
- Very large depth of field, eliminating the need for autofocus or precise manual focusing;
- Due to the extreme angle of view and convex front element, front filters cannot be used;
- Often equipped with a filter turret with swivel-mounted filters;
- Often come with a small, built-in petal-shaped lens hood.
