Rokinon Xeen 14mm T3.1 Lens for Canon EF Mount – Ultra-Wide Professional Cine Prime
The Rokinon Xeen 14mm T3.1 Lens for Canon EF Mount is a high-performance ultra-wide-angle cinema prime lens designed specifically for filmmakers demanding excellent optical precision, full-frame coverage, and robust, professional handling. This lens is part of Rokinon's acclaimed Xeen Cine line, built to seamlessly fit into high-end cinematography workflows with its optimized optics, advanced coatings, and cine-standard manual controls.
Ultra-Wide Perspective with Full-Frame Coverage
With a 14mm focal length, the Rokinon Xeen offers an expansive 84.1° diagonal angle of view on full-frame cameras, delivering sweeping panoramic imagery ideal for establishing shots, architectural interiors, dynamic landscapes, and wide narrative scenes. The broad field of view allows cinematographers to immerse their audience fully in the environment while maintaining clarity and accurate rendering of fine details.
The lens also maintains usability on Super 35 and smaller sensors, shrinking the effective angle of view to approximately 61.2°, balancing composition versatility across a range of camera bodies.
Bright T3.1 Aperture for Low-Light and Depth Control
Boasting a maximum aperture of T3.1, this cine lens excels in a wide range of lighting conditions, enabling natural and controlled depth of field effects for visually compelling storytelling. While ultra-wide lenses typically offer deep focus, the T3.1 aperture allows for subtle separation of subjects from backgrounds, contributing to artistic cinematography.
A 9-blade rounded aperture diaphragm ensures smooth, natural bokeh, complementing the expansive imagery with refined visual aesthetics in out-of-focus regions.
Advanced Optics with X-Coating Technology
Rokinon engineered the Xeen 14mm with 14 optical elements arranged in 10 groups, including several high refractive index and extra-low dispersion (ED) elements, along with hybrid and spherical aspherical components. This complex glass arrangement minimizes chromatic aberration, distortion, and flare, producing sharp, high-contrast images that maintain color accuracy essential for 4K and higher-resolution video production.
Further enhancing image fidelity, the lens features proprietary XEEN X-Coating Technology designed to reduce ghosting and flare while maximizing light transmission.
Cinema-Grade Manual Controls for Precise Operation
This lens is equipped with industry-standard 0.8 MOD gearing on its focus and aperture rings, making it compatible with follow focus systems, iris motors, and other professional accessories. This standardization facilitates quick lens swaps on rigs without recalibrating focus accessories.
The focus ring provides approximately 200° of smooth rotation for precise, repeatable focus pulls essential in narrative and creative video productions. The aperture ring is de-clicked, allowing continuous, silent iris adjustments during recording, preserving audio clarity and smooth lighting transitions.
Dual focus and T-stop scales are meticulously printed on both sides of the lens barrel with glow-in-the-dark paint to ensure legibility in dim or blackout environments, improving workflow efficiency in demanding setups.
Compact, Durable Design Built for Professional Use
Constructed with a rugged all-metal body, the lens measures about 100mm in length and 117.6mm in diameter, weighing roughly 1,170g. The robust build delivers reliability during rigorous production schedules while remaining manageable on handheld, stabilizer, and studio rigs.
The lens is designed with a non-rotating front element and a standardized 114mm front diameter, allowing quick and easy use with matte boxes and professional cinema filters.
