The Rokinon 8mm T/ 3.8 Fish Eye HD Cine Lens is a Fisheye lens with a 180° field of view that features a use on cameras and camcorders with a Sony E Mount. This lens provides the signature fisheye distortion on full frame and APS-C sized sensors, without having to add additional optics or post production image processing that can severely degrade image quality. Designed for shooting HD video, it features a silent iris ring for smooth iris pulls and both the focus and iris rings have built-in gears to accommodate follow focus and iris motors.

The lens features an internal focus design which keeps the front of the lens from turning as focus is changed.

The optical design consists of 10 elements in 7 groups with 1 aspherical element to deliver a crisp image with minimal chromatic aberrations across the imaging field. The lens has an aperture range of T 3.8 to 22, and you can close focus down to 12 inches from the image plane. It features a removable Tulip shaped lens hood.
