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.

Notes

• This non-AI lens was designed for Nikon F, F2, Nikkormat FS, FT, FT2, FTN, EL, ELW 35mm film SLR cameras.
• Non-AI lenses cannot be used on Nikon digital SLR cameras (except for the Df) or late (AI) film SLR cameras. However, non-AI lenses can be fitted to Nikon FM, FE, EL2, F3, F4 and Nikkormat FT3 cameras which used the AI metering system but allowed the metering coupling lever to be disengaged. The F5 could have this mechanism fitted as an optional extra. Non-AI lenses can be also fitted to the Nikon F2A and F2AS cameras because the AI mechanism was fitted to the removable metering prism.
