Rokinon 50mm T1.5 AS UMC Cine DS Lens for Canon EF Mount

The Rokinon 50mm T1.5 AS UMC Cine DS Lens, designed for Canon EF Mount, is a high-performance manual focus prime lens. It features an impressive maximum aperture of T1.5, which enhances low-light performance and allows for precise control over shallow depth of field, complemented by an 8-blade iris that produces aesthetically pleasing bokeh. Tailored for cinematic and video production, the lens includes focus and aperture control rings equipped with industry-standard gearing, facilitating compatibility with traditional follow focus systems. The aperture control ring is designed to be de-clicked, enabling seamless iris adjustments. Additionally, the lens barrel is marked with bright aperture and distance indicators oriented laterally, promoting ease of use for focus pullers.

This 50mm lens boasts a minimum focusing distance of 1.5 feet. Its internal focusing mechanism minimizes lens breathing, ensuring a stable angle of view during focus adjustments. The optical construction consists of 9 elements arranged in 6 groups, incorporating one aspherical element and one hybrid aspherical element to mitigate optical aberrations. Furthermore, a multi-coating on the lens enhances light transmission while reducing flare and ghosting effects. The filter thread diameter measures 77mm.

With the introduction of this 50mm lens, Rokinon expands its DS series of cinema lenses, establishing a cohesive identity beyond mere nomenclature. Each DS lens is designed with consistent alignment of geared focus and aperture rings, allowing for effortless transitions between lenses without the need for re-adjustment of follow focus and other rig accessories. Moreover, all DS lenses undergo rigorous testing to ensure color matching within the series, delivering uniform color and contrast during video shoots. Finally, focusing scales are marked on both sides of the lens barrel, facilitating adjustments from either side of the camera.

• Standard length manual focus prime lens for EF mount cameras.
  
  
• Functional as still photo lens but optimized for cinema and video shooting with geared aperture and focus rings, de-clicked aperture for smooth exposure transitions and laterally printed aperture and distance markings. The 50mm T1.5 is part of the DS series of cine lenses, sharing characteristics and features that unify the series and make it easier for users to swap out lenses when shooting video. Each DS lens provides aligned focus and aperture rings so that readjustment of the follow focus is not necessary when switching lenses. Also each lens has been tested to match color and contrast for a consistent look and less potential post-processing. Finally, all DS lenses print focus scales on each side of the lens barrel for ease of use from both sides of the camera.
