Manufacturer description #1

This is a equidistant projection type of fish-eye lens which expands the use of the FD series of lenses and the Canon F-1 system. A 180° angle-of-view is taken in a 23mm diameter circle in the 24mm x 35mm picture frame. An 11-element, 8-component construction, it has six built-in filters.

Its reduced size is the same as that of standard lenses.

Because it is equipped with an equidistant projection mechanism, it is ideal for photographing astronomical and azimuth phenomena. When used in ordinary photography, it is particularly suitable in achieving special effects.

It can be used to see the field-of-view through the viewfinder without fixing the mirror upward.

Manufacturer description #2

This is an equidistant-projection fish-eye lens that covers an angle of 180°. The resulting image is a 23mm-diameter circle. This lens was originally developed for academic purposes, but now it is frequently used for artistic and other purposes because of its characteristic circular image.

Since fish-eye lenses have a short focal length, close to the film plane, the mirror usually has to be raised before photographing. However, with this Canon fish-eye lens, this inconvenience is eliminated. This lens has a built-in filter mechanism with SKY, Y3, O, R, CCA4 and CCB4 filters. Exposure is manually set and focus does not have to be adjusted because of its deep depth of field.

Manufacturer description #3

This is a real fish-eye lens of the equidistant projection type, with a picture plane diameter of 23mm and covers a picture angle of 180°. Of the retrofocus type, with 11 elements in 8 groups, it has six built-in filters. Field of view can be seen through the viewfinder without having to lock the mirror up.

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.

From the editor

The lens features fixed focus design: there is no focusing ring and everything is in focus from the closest focusing distance of 30 cm to infinity.
