​The 135mm f/2.0 ED UMC Lens from Rokinon is a manual focus telephoto prime lens useful for portraiture and most telephoto applications. Its fast f/2.0 maximum aperture is effective in low light and enables shallow depth of field control. With a rounded 9-blade diaphragm, shallow depth of field imaging will be rendered with pleasing out-of-focus highlights. Compatible with both full frame and APS-C format mirrorless E mount cameras, this lens provides a 35mm focal length equivalence of 202.5mm when used on APS-C cameras. Its minimum focus distance is 2.6'.

The optical design includes one extra-low dispersion lens element to control chromatic aberration, contributing to sharp, color-accurate imaging, and each of its lens elements features Ultra Multi-Coating to improve light transmission and reduce ghosting and flare. An internal focus system prevents the front end from rotating which allows more effective use of variable filters.

A durable metal barrel with a wide focus ring and manual aperture control ring offer tactile control over focus and exposure. An included, removable lens hood deters stray light from entering the lens, while protecting it from accidental impact and precipitation.

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.
