Rokinon DS12M 12mm T3.1 Rokinon 12mm T3.1 Full Frame Cine DS Fisheye Lens

The Rokinon 12mm T3.1 ED AS IF NCS UMC Cine DS Fisheye Lens is optimized for digital cinematography, and as such comes equipped with a de-clicked manual aperture for smooth, silent adjustment along with unified focus and aperture gears for use with follow focus accessories. Additionally, focus, aperture, and depth of field markings are located on the side of the lens, in order to aid focus pullers who typically work on the side of the camera. Aperture is measured in absolute T-stops, providing accurate and consistent exposure across lenses, along with color rendition that is matched with other Rokinon cine lenses for consistency.

This fisheye lens offers a 180º diagonal view angle on full-frame cameras for an ultra-wide angle, distorted perspective that is useful for architectural interiors, landscapes, and creative experimentation in any application. The T3.1 maximum aperture is effective in low light situations, enabling some measure of control over shallow depth of field.

The lens' optical design, consisting of 12 lens elements arranged in 8 groups, includes three (3) elements made of low dispersion ED glass and two (2) aspherical lens elements to minimize coma and chromatic aberrations. Highly effective nano crystal anti-reflection (NCS) coating applied in conjunction with UMC coatings improve light transmission and reduce ghosting. The lens' internal focus system does not extend the front elements during focus, minimizing the effects of lens "breathing".

Rokinon 12mm T3.1 ED AS IF NCS UMC Cine DS Fisheye Lens Features:

• This Canon EF Mount manual focus lens optimized for digital cinema provides a de-clicked manual aperture for smooth and silent adjustment and unified focus and aperture gears for use with a traditional follow focus. Also, focus, aperture, and depth of field markings are on the side of the lens to aid focus pullers who typically operate on the side of the camera. Aperture is measured in absolute T-stops to provide accurate and consistent exposure across lenses and color rendition is matched with other Rokinon cine lenses for consistency.
• An ultra wide-angle fisheye lens with a 12mm focal length on full-frame cameras and an 19.2mm equivalency when used on APS-C and Super 35mm format cameras. Its distorted perspective is useful for interiors, landscapes, group shots and many creative wide-angle applications.
• Extra low dispersion and aspherical lens elements reduce aberrations for sharp, color-accurate imaging.
• Nano crystal coating and ultra multi-coating on the lens elements improves light transmission and reduces ghosting and flare.
• Sturdy metal barrel with removable petal-shaped lens hood.
