Product Overview +

High-Performance Wide-Angle Cinema Optic

The 18 mm T2.1 wide-angle prime lens is built to meet the rigorous demands of feature film, commercial, and high-end television production. Engineered for exceptional optical clarity and color matching, it provides sharp, high-contrast images with virtually zero distortion—perfect for capturing expansive landscapes, tight interiors, and dynamic master shots in 4K, 6K, and 8K resolutions.

Extreme Close-Focus Versatility

Boasting an ultra-short close focus distance of just 0.2 m (8 inches) from the image plane, this lens offers extraordinary compositional flexibility. Cinematographers can position the camera extremely close to talent or key props, creating compelling wide-angle perspectives while maintaining sharp focus and natural background fall-off.

Streamlined On-Set Ergonomics

Weighing only 1.4 kg (3.1 lb) with an overall length of 117 mm (4.6 inches), this lens offers a lightweight and balanced footprint on cinema rigs, gimbals, and jib arms. Its industry-standard 95 mm front diameter ensures seamless compatibility with standard cinema matte boxes, follow focus units, and motor drives for fast lens changes on set.
