Rokinon 12mm T3.1 ED AS IF NCS UMC Cine DS Fisheye Lens for Nikon F Mount
Ultimate Ultra-Wide Angle Cinematic Tool
The Rokinon 12mm T3.1 ED AS IF NCS UMC Cine DS Fisheye Lens for Nikon F mount is a powerful wide-angle cinematic lens designed for filmmakers and videographers. It offers a 180-degree diagonal fisheye perspective, enabling filmmakers to capture ultra-wide immersive videos and photos with breathtaking distorted views. Optimized for full-frame Nikon DSLRs, this fisheye lens combines advanced optical features, a bright T3.1 aperture, and cinema-focused manual control with rugged build quality, making it one of the most versatile and creative tools for cinematic storytelling and experimental videography on Nikon’s full-frame cameras.
Ultra-Wide 180° Fisheye Coverage for Creative Visuals
With a 12mm focal length providing a 180-degree diagonal angle of view, this fisheye lens captures expansive scenes with pronounced barrel distortion, creating a unique artistic look that emphasizes curves, lines, and exaggerated perspectives. This makes it ideal for architectural interiors, environment shots, landscapes, and creative effects where dramatic wide-angle distortion immerses the viewer in the scene.
On APS-C Nikon cameras, the lens renders an approximately 19.2mm equivalent perspective, still offering an impressively wide and dramatic field of view suitable for a range of cinematic and creative applications.
Bright T3.1 Aperture for Low Light and Selective Focus
The fast T3.1 aperture grants excellent light transmission, enhancing low-light shooting capability without the need for excessive ISO boost or artificial lighting. While fisheye lenses typically emphasize wide angles over depth of field, this aperture allows some selective focus and shallow depth of field effects, lending subtle cinematic separation even with the extremely wide field.
The lens features a durable 7-blade rounded iris that produces smooth and natural bokeh, rounding out the visual storytelling potential beyond just wide capture.
Advanced Optics with ED, Aspherical, and Nano Coating Technology
The optical design consists of 12 elements in 8 groups, including three Extra-Low Dispersion (ED) glass elements and two aspherical lenses. These specialized components minimize typical fisheye issues such as chromatic aberrations, color fringing, and distortions beyond the creative fisheye effect, resulting in sharp, high-contrast imagery throughout the frame.
Multi-layer Nano Crystal Coating (NCS) and Ultra Multi Coating (UMC) work together to reduce lens flare and ghosting, ensuring clear images even in conditions with strong light sources or backlighting challenges. These coatings improve light transmission and color fidelity, making the lens suited for the demands of modern high-resolution 4K and beyond video productions.
Cinema-Grade Manual Operating Features
The lens is built with manual focus and aperture rings featuring 0.8 MOD gear pitch, compatible with follow focus systems and iris motors to integrate seamlessly with professional cinema rigs. The focus ring offers about 200 degrees of smooth rotation, allowing fluid and precise focus pulls essential for controlled cinematic shots.
The aperture ring is fully de-clicked, enabling uninterrupted and silent exposure adjustments during takes, a crucial feature for maintaining sound integrity on set. Markings for aperture, focus distance, and depth of field are printed on both sides of the lens and coated with glow-in-the-dark paint, ensuring usability in blacked-out or dimly lit environments.
Robust Build with Practical Accessories
Manufactured with a sturdy metal barrel, the lens balances professional durability with manageable weight and size (approximately 525 grams and 72.7mm length). Its removable petal-shaped lens hood offers effective protection and reduces flare when shooting without matte boxes.
Though this fisheye lens does not accept standard screw-in filters due to its bulbous front element shape, it compensates with robust build quality and versatile mounting options suitable for a wide range of shooting styles.
