Rokinon 8mm T3.8 Cine UMC Fisheye CS II Lens for Micro Four Thirds Mount
Creative Ultra-Wide Cinema Lens
The Rokinon 8mm T3.8 Cine UMC Fisheye CS II Lens for Micro Four Thirds (MFT) mount is a specially crafted ultra-wide fisheye cine lens that provides filmmakers, videographers, and content creators with immersive, dramatic 180° diagonal fisheye perspectives. This lens is designed for Micro Four Thirds cameras, combining a compact form with professional optical performance, cinema-grade manual controls, and advanced coatings that deliver unique creative possibilities and the trusted reliability of Rokinon’s Cine DS series.
Exceptional Ultra-Wide Fisheye Perspective
The 8mm focal length captures a striking 180-degree diagonal angle of view on Micro Four Thirds sensors, filling the frame with exaggerated fisheye distortion that curves straight lines and creates visually engaging expansive scenes. This lens is perfect for architectural interiors, landscapes, special effects, action cinematography, and experimental filmmaking where a wide, hyper-real aesthetic is desired.
Though traditionally used for artistic effects, the fisheye perspective provides a special tool for immersive storytelling, allowing creators to visually play with space, movement, and spatial relationships in ways conventional lenses cannot replicate.
Balanced Aperture for Cinematic Applications
Equipped with a bright T3.8 maximum aperture, the lens provides enough light intake for shooting in a variety of lighting conditions, including natural low-light environments. While fisheye lenses typically capture large depths of field, the T3.8 aperture enables fine control over exposure and a subtle but pleasing degree of subject separation and background softness.
The 7 rounded iris blades contribute smooth and appealing bokeh, making the lens capable of producing cinematic imagery with visual flair despite its ultra-wide and distorted nature.
Advanced Optics with Hybrid Aspherical Elements and UMC Coating
This lens is optically composed of 10 elements arranged in 7 groups, including a hybrid aspherical element specifically designed to reduce common fisheye lens aberrations such as chromatic fringing, spherical distortion, and haziness. These elements deliver crisp, contrast-rich images sharp from center to edges, essential for high-definition video production.
To address common issues like flare and ghosting, the lens benefits from Samyang’s Ultra Multi Coating (UMC), which enhances color fidelity and contrast by minimizing internal light reflections—critical for maintaining image clarity even in bright or backlit shooting scenarios.
Professional Cinema-Grade Manual Controls
The cine-specific design integrates industry-standard 0.8 MOD gear teeth on both the focus and aperture rings, making it fully compatible with external cine accessories such as follow focus units and motorized iris controls. This gearing ensures smooth, repeatable adjustments essential for fast-paced and complex film shoots.
The focus ring features a generous throw of approximately 200 degrees to allow precise cinematic focus pulling. The aperture ring is de-clicked, providing frictionless, silent iris transitions to smoothly adjust exposure without disrupting audio recording or visual flow.
Dual-sided markings for T-stops and focus distances are printed on the lens barrel using glow-in-the-dark paint, making them visible and easily readable in dark or blackout studio environments—a thoughtful feature for demanding production workflows.
Compact, Durable Build Tailored for MFT
The Rokinon 8mm T3.8 Cine UMC Fisheye CS II lens is compact and lightweight, weighing approximately 465 grams with a length of about 72.6mm, making it an excellent choice for handheld, gimbal-stabilized, and studio rig configurations on Micro Four Thirds cameras. Its robust metal construction contributes to long-term durability without compromising portability.
A tulip-style removable lens hood helps minimize flare and protects the prominent bulbous front element. Due to the curvature and size of the front glass, this lens does not support standard screw-in filters but can be used with matte boxes for professional filter changes.
