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 (*).

(*) Some APS-C models have a detachable lens hood, which allows such lenses to be used on 35mm full-frame cameras as circular fisheyes.

From the editor

A very compact and lightweight fisheye lens with a fixed speed of F/5.6, which allows for a simple optical formula. The ascetic barrel has only one control element: the manual focusing ring. As with the Pergear 7.5/2.8 Fisheye HD MC, the focusing distance scale is marked in such a way that most of it is taken up by distances from the closest to 1m, which automatically implies that the lens is optimized for close-up shooting. The short closest focusing distance of 0.15m allows you to take close-ups with an unusual distorted perspective.

The lens is also sold under the names "Cheecar Fish-eye F5.6 10mm" and "RISESPRAY Fish-eye 10mm/5.6" (with the closest focusing distance of 0.1m).
