Rokinon 20mm T1.9 Cine DS Lens for Micro Four Thirds
Ultra-Wide, Bright Cine Prime for Versatile Filmmaking
The Rokinon 20mm T1.9 Cine DS lens for Micro Four Thirds is a specialized cinema lens engineered to deliver stunning ultra-wide coverage, professional manual controls, and vibrant image fidelity. Designed specifically for Micro Four Thirds sensor cameras, this cine prime suits narrative storytelling, documentaries, virtual production, and any project requiring immersive wide perspectives combined with creative depth of field management.
Ultra-Wide Optical Design
The 20mm focal length on Micro Four Thirds sensors provides a wide 56.1° diagonal angle of view, ideal for capturing vast landscapes, dynamic interiors, architecture, and crowded scenes with a sense of depth and scale. This wider frame facilitates creative environmental shots while maintaining edge-to-edge clarity thanks to the lens’s sophisticated optical design.
Fast T1.9 Aperture for Low-Light Shooting and Depth Control
The T1.9 aperture is substantial for an ultra-wide lens, letting filmmakers capture sharp footage in lower lighting conditions without resorting to high ISO settings. This aperture also enables selective focusing by producing a shallow depth of field when framing close to subjects—outstanding for creative effects and narrative emphasis despite the wide lens format.
The lens utilizes an 11-blade rounded iris to create smooth, aesthetically pleasing bokeh, enhancing out-of-focus backgrounds with a cinematic softness full of character.
Advanced Optical Elements and Anti-Reflective Coatings
With 13 elements grouped in 12 specialized groups, including hybrid aspherical lenses optimized for reducing chromatic aberration and distortion, the lens produces sharp images with accurate colors and impressive contrast. The multi-layer Ultra Multi Coating (UMC) applied on elements significantly reduces lens flare and ghosting, providing excellent image fidelity even in challenging lighting scenarios including backlit and high-contrast environments.
Professional Cinema Controls for Precision
The Rokinon 20mm Cine DS lens features industry-standard 0.8 MOD gear rings on both focus and aperture barrels, ensuring smooth and repeatable control compatible with follow focus systems widely used on professional film sets. This uniformity allows cinematographers and camera assistants to work across lenses with standardized gear positions for rapid adjustments and minimal rig changes during shoots.
The de-clicked aperture ring offers silent iris control, enabling seamless exposure transitions without audio interference. The focus ring features approximately 200º rotation for precise pulling, essential for cinematic techniques requiring fluid shifts of focus.
To support versatile shooting configurations, the lens has dual markings for T-stop and focus distances printed on both sides of the lens barrel and coated with luminescent paint to maintain visibility in complete darkness or controlled lighting conditions.
Durability and Practical Features
Constructed with a robust metal body, this lens measures approximately 117.6 mm in maximum diameter and 120.1 mm in length for the MFT mount, weighing around 541 grams. Its built-in petal-shaped lens hood aids in controlling unwanted lens flare, useful when shooting in direct sunlight or artificial studio lights.
A 77 mm threaded front allows creative use of neutral density filters, polarizers, or diffusers to adjust exposure and contrast dynamically.
Minimum Focusing Distance
A minimum focusing distance of 0.2 meters (about 7.8 inches) provides versatile shooting options even at close range, enabling expressive wide-angle close-ups where the subject can be isolated creatively using the lens’s bright aperture and selective focus capabilities.
