The Rokinon 14mm T3.1 Cine ED AS IF UMC Lens was developed primarily for film and video applications. The cine version of Rokinon's 14mm lens features industry-standard gearing for the focus and aperture ring, and the aperture ring has been de-clicked for smooth iris pulls. The aperture and focus scales have also been relocated to the side of the lens, where it is easier for focus pullers to read them.

This lens is compatible with full-frame sensors and can also be used on APS-C-sized sensors, where the 35mm-equivalent focal length will be 22.4mm. The optical construction incorporates three high refractive index elements, two extra-low dispersion elements, one hybrid aspherical elements, and one aspherical element to reduce chromatic aberration and distortion to produce sharper imagery. Additionally, a UMC coating has been applied to lens elements to minimize lens flare and ghosting for more contrast-rich images.

  • Fast T3.1 maximum aperture benefits working in low-light conditions.
  • Three high refractive index elements, two extra-low dispersion elements, one hybrid aspherical element, and one aspherical element reduce chromatic aberrations in order to produce greater sharpness and clarity.
  • UMC coating improves light transmission and suppresses lens flare and ghosting for more contrast-rich, color-neutral images.
  • Geared aperture and focus rings are compatible with standard follow focuses for greater control over adjustment.
  • De-clicked aperture ring facilitates smooth, quiet exposure adjustments during recording.

1. Rokinon MTF charts use theoretical equations to plot performance and do not rely on subjective 
opinion, subject matter, camera features, software or other factors. They plot the contrast and resolution of a lens from the center to its edges, against a "perfect" lens that would transmit 100% of the light that passes through it. The contrast of a lens is important because it directly relates to resolution.

3. Rokinon tests are carried out with the lens at its maximum (widest) aperture (Ex. 24mm F1.4 lens is measured at F1.4 for MTF).

4. Zero on the chart’s X-axis (horizontal axis) 
represents the center of the lens. As a line moves right, it indicates the change of contrast and sharpness from the center to the edge of the image. 

5. The Y-axis (vertical axis) plots the transmission of light through the lens. It has a maximum value of "1.0" to indicate 100% transmittance of the light, which is not possible to achieve. 

6. The blue graph lines (10 lines/mm) represent contrast measurement. The red graph lines (30 lines/mm) represent resolution.

7. Sagittal lines (thick lines) represent the contrast 
measurements of line pairs that are parallel to an imaginary diagonal line that runs from the bottom left hand corner to the top right hand corner of a image frame. Meridonial lines (thin lines) represent line pairs that are perpendicular to the imaginary diagonal line.

8. The higher and straighter the blue lines, the better the contrast. The higher and straighter the red lines, the better the resolution.
