​The 12mm f/2.8 ED AS IF NCS UMC Fisheye Lens from Rokinon 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 photographic application. The f/2.8 maximum aperture is effective in low light situations and enables some measure of shallow depth of field control. 

The lens' sophisticated 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 nanocrystal anti-reflection (NCS) coating applied together with UMC coatings improve light transmission and reduce ghosting. Its internal focus system enables its compact design and keeps the front element from extending during focus.

As a manual focus, manual aperture lens, it offers a wide, easy to grip focus ring and bright aperture, distance and depth of field markings. A removable petal-shaped lens hood is included. 

  • An ultra wide-angle fisheye lens with a 12mm focal length on full-frame cameras and a 19.2mm equivalency when used on APS-C 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.
  • Manual focus lens with an internal focus system and wide, rubberized focus ring.
  • Manual aperture control with bright markings for aperture, distance and depth of field.
  • Sturdy metal barrel with removable petal-shaped lens hood.

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.
