The Rokinon 8mm F3.5 Fisheye is an ultra-wide diagonal fisheye lens with an angle of view of approximately 180° and an exaggerated perspective. On an APS-C camera it fills the frame. On a full-frame digital or 35mm film camera it produces a circular, vignetted image that floats in the frame and does not cover the whole sensor or film area.
The optical design has 10 glass elements in 7 groups, including hybrid aspherical elements. An ultra multi-coating reduces flare and ghost images. A built-in petal-shaped lens hood is part of the lens.
Focusing is manual. The lens has no electronic connections for autofocus or metering. It focuses as close as 11.8" (0.3 m).
