The Rokinon 12mm T3.1 VDSLR ED AS NCS is a lens optimized for digital cinematography and as such provides a de-clicked manual aperture for smooth and silent adjustment and unified focus and aperture gears for use with follow focus accessories. 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 VDSLRs for consistency.

This fisheye lens provides a 180º diagonal angle of view 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 and enables some measure of shallow depth of field control.

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

  • 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.

Optical Construction

De-clicked aperture and calibrated in T-stops

Apertures are de-clicked for precise, smooth and silent operation. Calibrated in T-stops to provide accurate and consistent exposure.

Industry-standard gearing for focus and aperture rings

Each lens in the Rokinon DS series shares common focus and iris gear ring positions, which speeds up lens changes as accessories such as follow focus units or iris motors don't have to be re-positioned.

Dual sided lens markings

To aid focus pullers who have to work both sides of the lens, the aperture and focus scales are marked on both sides of the lens.
