The Rokinon 10mm f/2.8 ED AS NCS CS Lens is a prime, manual focus wide-angle lens designed specifically for use with APS-C sized image sensors. Providing a 35mm-equivalent focal length of 16mm and a broad 105.9° angle of view, this lens is ideally suited for interior, architectural, and landscape photography applications. One extra-low dispersion element and two aspherical elements have been incorporated into the optical design to minimize chromatic aberrations and distortion in order to produce sharper images. Additionally, a Nano Coating System (NCS) has been applied to the lens elements in order to reduce surface reflections and prevent lens flare and ghosting for improved light transmission and more contrast-rich imagery.

  • Prime wide-angle lens provides a 35mm-equivalent focal length of 16mm, making it ideally suited for indoor, architectural, and landscape subjects.
  • Fast f/2.8 maximum aperture benefits working in low-light conditions.
  • Manual focus design permits selective control over focus placement.
  • One extra-low dispersion element and two aspherical elements reduce chromatic aberrations and distortions in order to produce sharper images.
  • Nano Coating System improves light transmission and suppresses lens flare and ghosting for more contrast-rich, color-neutral images.

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.
