Sigma 20mm T2.5 Cine Lens FF Classic F/AP2 ( Metric ) PL Mount / i-Technology
The Sigma 20mm T2.5 Cine FF Classic Prime Lens features a PL mount and metric markings, designed to deliver a classic film look alongside modern high-resolution performance. This compact lens combines lower contrast, enhanced flare and ghosting, and a nine-bladed iris to produce beautifully soft, buttery bokeh.
Key Features
- Classic Cinema Aesthetic: Utilises non-coated elements to provide lower contrast with enhanced flare and ghosting effects for a vintage film look.
- Full-Frame Sensor Coverage: Engineered for ultra-high resolution capture, offering complete coverage for full-frame sensors.
- Cooke /i Technology: Features built-in electronic communication to provide essential lens metadata for visual effects and post-production workflows.
- Standardised 95mm Front Diameter: Fits seamlessly with professional matte boxes and lens shades across the entire FF cine range.
- Metric Focus Markings: Linear focus and iris scales are clearly marked in metres for precise manual adjustments.
- ARRI PL Mount: Offers robust and reliable compatibility with a wide selection of professional cinema cameras.
With standardised colour reproduction across the entire classic lens line, colour correction in post-production is greatly simplified. This durable lens also features a protective coating on the front and rear glass elements to safeguard the optics against damage on set.
