Rokinon 50mm T1.5 AS UMC Cine DS Lens for Sony E-Mount – Precision Cinematic Prime Lens
The Rokinon 50mm T1.5 AS UMC Cine DS Lens for Sony E-Mount is a professional-grade prime lens designed to meet the high demands of filmmakers, cinematographers, and video content creators. Part of the Cine DS series, this lens combines optical excellence, fast aperture performance, and superior manual control to provide stunning cinematic imagery. Fully compatible with Sony’s E-mount full-frame cameras, the 50mm focal length is one of the most versatile and widely favored for creating natural yet emotionally compelling shots, making this lens a must-have for any filmmaker’s toolkit.
Classic 50mm Focal Length for Natural Cinematic Perspective
The 50mm focal length is often considered the “standard” or “normal” lens for filmmakers because it closely approximates human vision in terms of perspective and compression. With a diagonal field of view around 47 degrees on full-frame sensors, this lens offers a natural look that is neither too wide nor too telephoto, making it ideal for portraits, narrative storytelling, interviews, and medium shots.
This middle-ground focal length enables filmmakers to craft intimate scenes while maintaining spatial context, striking a balance between subject detail and environment. It captures characters and action realistically without distortion, allowing emotional expressions and subtle narrative details to shine.
Bright T1.5 Aperture for Creative Lighting and Depth of Field
A standout feature of the Rokinon 50mm Cine lens is its remarkably fast T1.5 aperture, allowing superb low-light performance and stunning control over depth of field. This bright aperture facilitates shooting in dim lighting without the need for excessive artificial augmentation, making it perfect for on-location shoots, nighttime scenes, or natural light interior settings.
The shallow depth of field at T1.5 lets filmmakers isolate their subjects from the background with creamy, smooth bokeh. This artistic control helps in emphasizing focal points and creating mood by blurring distracting elements in the background, thus enhancing storytelling and visual engagement. The lens achieves beautiful out-of-focus highlights thanks to its 9-blade rounded iris diaphragm, contributing to pleasing and natural bokeh aesthetics.
Advanced Optical Design Featuring Aspherical Elements and UMC
The 50mm Cine DS lens incorporates a high-performance optical formula consisting of 9 lens elements including hybrid aspherical glass elements. These advanced optics correct spherical aberrations and minimize distortion and chromatic aberrations, resulting in sharp, high-contrast images with vibrant color accuracy throughout the entire frame.
The lens is also equipped with Ultra Multi Coating (UMC) technology that effectively reduces ghosting and flare, which can degrade image quality especially when shooting against strong light sources or in backlit conditions. UMC keeps contrast and color fidelity intact even in challenging lighting environments, ensuring footage that meets professional cinematic standards.
Professional Cinema-Grade Manual Controls
Designed specifically for film production, the Rokinon 50mm T1.5 Cine DS features precise manual controls with focus and aperture rings equipped with standardized 0.8 MOD gear teeth. These gears are compatible with common follow focus systems and iris motors, enabling smooth, repeatable movements essential for narrative storytelling and complex visual sequences.
With roughly 200 degrees of focus rotation, the focus ring allows filmmakers to execute subtle, controlled focus pulls that create dynamic visual scenes. The de-clicked aperture ring facilitates quiet, fluid iris adjustments during takes, ensuring no unwanted audio interference or flicker in the recorded image.
The lens barrel features dual-sided engraved focus distance and T-stop scales, coated with glow-in-the-dark material to provide excellent visibility in low-light or dark studio conditions. This practical feature accelerates setup and operation during intense, fast-paced production workflows.
Robust Build Quality for Professional Use
The lens body is constructed entirely from metal, providing durability and reliability for demanding professional environments. Its balanced ergonomic design makes it comfortable to handle during handheld shooting or when mounted on gimbals, tripods, or rigs.
The lens hood is detachable and effectively reduces lens flare and protects the front element from potential damage. Its front filter thread measures 77mm, allowing the attachment of neutral density filters, polarizers, and specialty glass filters to modify exposure creatively or adjust reflections and colors.

The 50mm focal length and cinema-grade features render this lens highly versatile across a wide spectrum of filmmaking applications:
