Rokinon 50mm T1.5 AS UMC Cine DS Lens for Sony E Mount

The Rokinon 50mm T1.5 AS UMC Cine DS Lens for Sony E Mount is a high-speed manual focus prime lens designed for both APS-C and full-frame E-mount cameras. When used with APS-C sensors, it offers a full-frame equivalent focal length of 75mm. This lens 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 focus and aperture control rings are 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 that face laterally, simplifying operation for focus pullers.

The 50mm lens has a minimum focusing distance of 1.5 feet. Its internal focusing mechanism reduces lens breathing, ensuring a stable angle of view during focus adjustments. Constructed with 9 elements arranged in 6 groups, the lens includes one aspherical element and one hybrid aspherical element to minimize optical aberrations. Furthermore, a multi-coating on the lens enhances light transmission while mitigating 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 seamless 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, providing uniform color and contrast across the series during video recording. Finally, focusing scales are marked on both sides of the lens barrel, facilitating adjustments from either side of the camera.

• Compatible with both full frame and APS-C format E-mount cameras, this 50mm manual focus prime lens provides the 35mm focal length equivalent of 75mm on Sony E mount APS-C format 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.
