Home in on close-up subjects with the 100mm f/2.8 Macro Lens from Rokinon, which affords life-size 1:1 magnification along with a minimum focusing distance of 1'. This manual focus portrait-length lens also incorporates one high refractive index element and one extra-low dispersion element into its design to reduce chromatic aberrations and distortions throughout the focusing range. An Ultra Multi-Coating has also been applied to minimize flare and ghosting for increase contrast and color neutrality. A long focal length lens with close focusing abilities and a high magnification ratio, this macro lens is ideal for making close-up, detailed images of nearby subjects.

  • This 100mm f/2.8 lens features a Sony E mount, and is compatible with full-frame sensors or APS-C sensors, where it will provide a 150mm equivalent focal length.
  • A bright f/2.8 maximum aperture is useful for working in a variety of lighting conditions and the minimum f/32 aperture helps to attain a long depth of field when working with close-up subjects.
  • One high refractive index element and one extra-low dispersion element help to control chromatic aberrations and minimize distortions throughout the focusing and aperture ranges.
  • An Ultra Multi-Coating has been applied to lens elements to reduce lens flare and ghosting for increased clarity, contrast, and color fidelity.
  • Featuring a macro design, this lens affords a 1:1 maximum magnification ratio along with a minimum focusing distance of 1'.
  • Benefitting working with especially close subjects, this manual focus lens features an internal focus design to maintain the overall lens length during use. Additionally, the front filter mount does not rotate when focusing to better enable the use of polarizers, graduated ND, and other filter types that require precise positioning.
  • A rounded nine-blade diaphragm contributes to a pleasing out-of-focus quality when using selective focus or shallow depth of field techniques.

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.
