About Sigma T1.5 FF Cine

FEATURED REVIEWS

Bright, solid, and sharp.

By Justin M.

Beautiful, bright lenses that have a great build quality.

Become captivated by the unparalleled performance of the 50mm T1.5 FF Fully Luminous High-Speed Prime Cine Lens, a professional-grade tool designed for the discerning cinematographer and videographer. This high-quality lens is engineered to deliver stunning image quality, boasting full-frame compatibility in a remarkably compact form factor.

Crafted for excellence, the lens is optimized for 6K-8K resolution filming, enabling you to capture a variety of shots without the need to adjust lighting conditions, thus elevating your cinematography to new heights. The meticulous design, precision manufacturing, and rigorous inspection process ensure that every lens meets the highest standards. Sigma's proprietary A1 MTF measuring system, utilizing 46-megapixel Foveon direct image sensors, guarantees that even the most subtle high-frequency details are captured with exceptional clarity.

The advanced optical design minimizes flare and ghosting, enhancing contrast even in challenging backlit scenarios. Each prototype undergoes thorough testing to identify and eliminate any potential causes of ghosting. The result is a lens that combines razor-sharp resolution with a beautiful bokeh effect, satisfying the most demanding image quality requirements for both still and motion picture capture.

Consistency across the Sigma lineup is key, with standardized color balance across all lenses simplifying color correction and ensuring a cohesive look in your projects. The optical system, capable of resolving 50-megapixel or higher in still photography, is ready to tackle higher resolution shooting and is perfectly suited for chroma keying applications.

In terms of build quality, this lens is a testament to Sigma's commitment to lightweight and compact design without compromising on durability. The dust-proof and splash-proof construction, akin to that of the Sigma 150-600mm F5-6.3 DG OS HSM/Sports lens, ensures reliability in even the most challenging environments. The 100% metal body is built for the rigors of professional use, while the luminous paint on the lens markings enhances visibility in low-light conditions.

The lens features a standardized 82mm front filter size for convenience and a 95mm front diameter compatible with a wide range of matte boxes. Gear positions on the rings are standardized for seamless integration with follow focus systems and accessories, and the 0.8M gear pitch is in line with industry standards. Silent ring stoppers with special resin dampers allow for quiet operation, crucial for sound-sensitive environments.

The focus ring's 180-degree rotational angle offers precise control, and the optimized cam design facilitates easy long-distance focusing. The iris ring provides full manual control with a smooth, click-less operation, and the T-stop display ensures accurate exposure settings. The linear iris ring allows for intuitive and direct control over the aperture.

The mount includes electronic contacts for communication with the camera body, relaying essential information such as focal length and aperture. A dedicated lens support foot is included to reduce strain on the camera body and enhance mount stability, with multiple screw holes for added versatility. Finally, the lens comes with a cine-style front lens cap, maintaining the professional standards expected by industry professionals.

In summary, the 50mm T1.5 FF Fully Luminous High-Speed Prime Cine Lens for PL Mount is a reliable, durable, and versatile choice for filmmakers and videographers seeking a high-performance lens that excels in both image quality and construction. Whether shooting portraits, street scenes, or fast-moving subjects, this lens is poised to become an indispensable part of your cinematic toolkit.
