Manufacturer description #1

A large aperture full-frame fisheye lens with 180° diagonal angle of view. This lens had the world largest aperture of f/2.8 in its class at the time. This lens is called "full-frame fisheye lens" to distinguish from circular fisheye lenses, which produce circular images that do not fill the entire frame.

This is a fish-eye lens for general photography developed to follow the 7.5mm one. It is the smallest fish-eye lens in the world. It was developed as one of the FD lenses and consequently it has an extremely high quality of performance.

Because of its retrofocus design, the mirror does not have to be set upward. From the point of view of light metering, as well as photography in general, it operates as well as a standard lens.

Its f/2.8 brightness ranks well above the best, and it has full compensation of every aberration in the total 180° area. Special effort was done to enable it to avoid the aberration of magnification, and it has a sharp delineation up to the corner areas. Furthermore, in order to solve the problem of ghost and flare which tend to occur with this type of lens, the procedure of multiple coating was employed.

It will actually focus closer than the minimum focusing distance of 0.3m on the lens scale, enabling closest shooting distance of 0.2m at smaller aperture. As filters cannot be attached to the lens front, four filters, SKY, Y3, O and R are built-in.

Manufacturer description #2

A fish-eye lens for ordinary photography, it covers diagonally an angle of 180°. Its F2.8 speed ranks well above the fastest, and can also be used without lifting the mirror. It compensates every aberration perfectly throughout the 180°, and the multi-layer coating gives a sharp picture image. It has built-in filters easily set.

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.
