The Rokinon 12mm T3.1 ED AS IF NCS UMC Cine DS Fisheye Lens, designed for Sony E-Mount, is specifically tailored for digital cinematography. It features a de-clicked manual aperture, allowing for smooth and silent adjustments, and incorporates unified focus and aperture gears compatible with follow focus systems. Additionally, the lens is equipped with focus, aperture, and depth of field markings positioned on the side, facilitating the work of focus pullers who typically operate adjacent to the camera. The aperture is indicated in absolute T-stops, ensuring precise and consistent exposure across various lenses, while the color rendition is harmonized with other Rokinon cine lenses to maintain uniformity.
This fisheye lens offers a 180º diagonal angle of view on full-frame cameras, delivering an ultra-wide perspective that is particularly advantageous for architectural interiors, landscapes, and creative experimentation across diverse applications. The T3.1 maximum aperture performs well in low-light conditions and provides some control over shallow depth of field.
The optical construction of the lens comprises 12 elements organized into 8 groups, including three low dispersion ED glass elements and two aspherical elements, which work together to reduce coma and chromatic aberrations. The application of advanced nano crystal anti-reflection (NCS) coating, in conjunction with UMC coatings, enhances light transmission and minimizes ghosting. Furthermore, the internal focus mechanism prevents the front elements from extending during focusing, thereby reducing the impact of lens breathing.
- This manual focus lens, designed for Sony E-Mount and optimized for digital cinema, features a de-clicked manual aperture that allows for smooth and silent adjustments. It includes unified focus and aperture gears, facilitating compatibility with traditional follow focus systems. Additionally, the lens is equipped with focus, aperture, and depth of field markings positioned on the side, assisting focus pullers who generally work alongside the camera. The aperture is indicated in precise T-stops, ensuring accurate and consistent exposure across various lenses, while the color rendition is harmonized with other Rokinon cine lenses for uniformity.
- A fisheye lens featuring an ultra wide-angle design with a focal length of 12mm for full-frame cameras, which translates to an 18mm equivalent when utilized on APS-C and Super 35mm format cameras. The lens's distinctive distortion is advantageous for capturing interiors, landscapes, group photographs, and various innovative wide-angle uses.
- 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.
