The Blackmagic Design R9842060 TLD Zoom 1.6-2.0:1 Lens is a high-quality, manual parfocal zoom lens specifically designed for use with Blackmagic Studio Cameras and other compatible cameras featuring a B4 lens mount interface. This lens is engineered for broadcast and studio environments where smooth, repeatable zoom and focus operations are critical, such as news studios, live sports broadcasting, and corporate production. The "TLD" designation indicates it utilizes Blackmagic's Tally Lens Data protocol, allowing the camera to read and display crucial lens metadata like focal length, zoom position, and focus distance directly in the viewfinder and for recording into file metadata.

Optically, the lens offers a versatile 1.6x to 2.0x zoom ratio, typically covering a focal length range suitable for medium to tight shots in a studio setting (e.g., approximately 8.5mm to 17mm on a 2/3-inch sensor, equivalent to a much longer range in full-frame terms). It is designed as a parfocal lens, meaning it maintains focus on a subject throughout the entire zoom range—an essential feature for professional live operation. The lens features smooth, geared manual control rings for zoom and focus, designed to be operated directly or optionally connected to a follow focus system.

The build is robust, with a metal lens barrel and a standard B4 bayonet mount that securely attaches to compatible cameras. The integrated TLD communication ensures seamless integration with Blackmagic's camera control systems, enabling features like virtual focal length overlays and data logging. By providing reliable optical performance, essential parfocal stability, and full data integration, this zoom lens is a key component for building a professional, manually-operated studio camera rig within the Blackmagic ecosystem.
