Unmatched Optical Performance
The Rokinon 20mm f/1.8 ED AS UMC Lens is built to impress even the most discerning photographers. Its 20mm focal length offers a broad 94.8° angle of view on full-frame sensors, allowing you to capture expansive vistas, interiors, and dramatic scenes without distortion.
The optical design consists of 13 elements in 12 groups, including two aspherical elements and three extra-low dispersion (ED) elements, which work together to minimize chromatic aberrations, distortion, and flare. This ensures superior image clarity and edge-to-edge sharpness, even at the lens’s maximum aperture.
Rokinon’s Ultra Multi-Coating (UMC) further enhances contrast and color fidelity by reducing ghosting and reflections. Whether shooting under bright sunlight or challenging lighting conditions, this lens ensures rich, accurate color reproduction and excellent image contrast.
Bright f/1.8 Aperture for Low-Light Brilliance

The fast aperture also allows for beautiful background separation and shallow depth of field, ideal for creating cinematic, dreamy bokeh in your images. Whether capturing stars in the night sky or focusing on a subject against a blurred background, this lens performs brilliantly in any environment.
Manual Focus Precision
Staying true to Rokinon’s tradition of precision control, the Rokinon 20mm f/1.8 ED AS UMC features a smooth manual focus ring, allowing photographers to fine-tune their shots with absolute accuracy. The manual focusing system provides tactile feedback and complete control, which is especially beneficial for video creators and astrophotographers who require pinpoint focus.
This feature allows for creative flexibility when shooting long exposures, focus stacking, or cinematic video sequences.
