The Rokinon 8mm f/2.8 UMC Fish-Eye II Lens is a prime fisheye lens specifically designed for APS-C sized image sensors. Providing a 35mm-equivalent focal length of 12mm and full 180° angle of view, this lens is well-suited for creative applications as well as interior and architectural subjects. Its fast f/2.8 maximum aperture is further beneficial to working in low-light conditions.

Three extra-low dispersion elements and two aspherical elements have been incorporated into the optical design to minimize chromatic aberrations and distortion in order to produce sharper images. Additionally, the lens' design features a built-in lens hood and a UMC coating has been applied to the lens elements to reduce surface reflections and prevent lens flare and ghosting for improved light transmission and more contrast-rich imagery.

  • 180° fisheye lens provides a 35mm-equivalent focal length of 12mm, making it ideally suited for interior and architectural subjects.
  • Fast f/2.8 maximum aperture benefits working in low-light conditions.
  • Three extra-low dispersion elements and two aspherical elements reduce chromatic aberrations and distortions in order to produce sharper images.
  • UMC coating improves light transmission and suppresses lens flare and ghosting for more contrast-rich, color-neutral images.
  • Built-in lens hood also helps to reduce lens flare and surface reflections.

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.
