The Rokinon 24mm f/1.4 ED AS UMC Lens gives you a substantial wide angle of view of 84° with full-frame Canon cameras. It can also be used with Canon APS-C cameras to provide a 57.6° angle of view basically equivalent to a 35mm lens on a full frame camera. It works well for landscapes, interiors, street photography and astrophotography.

Its 13 elements in 12 group design utilizes 4 Extra Low-Dispersion (ED) glass elements and 2 Aspherical elements to produce sharply defined images even in low lighting conditions. Focus can be as close as 9.84" for outstanding wide-angle close-up views.

Anti-reflection UMC coating (Ultra Multi Coating) enhances light transmission, increases contrast and reduces flare. The non-rotating 77mm filter mount provides allowseasy use of polarizers and other rotating filter types while the silky-smooth and perfectly-damped long throw action of the focusing ring provides precise focus control.

  • Ideal for landscapes, interiors, street photography, low-light photography, and astrophotography
  • Constructed with 2 Aspherical and 4 ED elements for outstanding, sharply defined images
  • UMC coating reduces flare and ghosting while increasing contrast
  • The non-rotating 77mm filter mount allows for easy use of polarizers and other rotating filter types

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.
