Rokinon 8mm T3.8 Cine UMC Fisheye CS II Lens for Sony E Mount
Ultra-Wide Cinematic Creativity
The Rokinon 8mm T3.8 Cine UMC Fisheye CS II Lens for Sony E Mount is a specialized ultra-wide fisheye cine lens designed for professional filmmakers and video creators. Offering a dramatic 180-degree diagonal field of view, this lens captures immersive and creative fisheye perspectives perfect for unique visual storytelling, architectural shots, and experimental work on Sony’s mirrorless full-frame and APS-C cameras. Combining advanced optics with cinema-grade manual controls, it is tailored to deliver striking fisheye imagery with smooth focus and exposure control.
Signature 180-Degree Fisheye Visual Impact
With its 8mm fixed focal length specialized for the fisheye effect, the lens delivers a full 180-degree diagonal angle of view on APS-C and full-frame Sony E-Mount cameras. This ultra-wide circular field wraps immense scenes dramatically around the frame with characteristic fisheye distortion, creating dynamic and immersive visuals that make scenes appear larger and more expansive.
The fisheye effect curves straight lines and adds exaggerated perspectives, providing creative options for filmmakers wishing to add a surreal, stylistic edge or showcase vast interiors and tightly packed environments with phenomenal breadth.
Bright and Functional T3.8 Aperture
The lens features a T3.8 maximum aperture, offering sufficient light transmission to shoot effectively in moderate light conditions. Although slower than typical wide cine primes, the T3.8 aperture balances aperture brightness with fisheye design constraints. It also allows some creative depth-of-field control, helping isolate subjects with pleasing background blur within the fisheye frame.
A smooth 7-blade rounded iris produces natural and round out-of-focus highlights that enhance the visual impact of shots.
Advanced Optical Design for Crisp Imagery
The optical formula involves 10 elements arranged in 7 groups, including one hybrid aspherical element. This design minimizes common fisheye aberrations such as chromatic aberration and haziness, delivering crisp edge-to-edge sharpness and high contrast.
The lens incorporates Samyang’s Ultra Multi Coating (UMC) to reduce flare and ghosting, helping maintain high color fidelity and contrast, even in scenes with bright light sources or backlighting.
Cinema-Grade Manual Control
Manual focus and aperture control ring gears are industry-standard 0.8 MOD, compatible with follow focus units and iris motors used in professional video production. The focus ring is damped with an approximate 200° rotation, allowing smooth, precise focus pulls crucial for cinematic video.
The aperture ring is de-clicked, enabling silent, continuous iris transitions during shooting without audible clicks or abrupt exposure changes, critical for maintaining consistent audio and video quality on set.
Dual aperture and focus distance markings on both sides of the lens barrel are coated with glow-in-the-dark paint, increasing legibility under low-light or blackout shooting conditions.
Practical Build and Ergonomics
Measuring roughly 101.1mm in length and weighing about 465 grams, the lens balances robust metal construction with portable form. A removable tulip-shaped lens hood protects against stray light and physical damage to the bulbous front element. The design precludes the use of screw-in filters, but the lens is compatible with matte boxes for external filtration and diffusion.
