Rent NowThe Rokinon 85mm T1.5 Cine DS is a manual-focus cine prime lens designed for Sony E-mount mirrorless cameras and camcorders, built specifically for video and cinema production rather than adapted from a still-photography lens design. As part of Rokinon’s Cine DS (Digital SLR/Cinema) lineup, it’s aimed at independent filmmakers, videographers, and content creators who want cine-style handling and a portrait-length focal length at an accessible price point compared to premium cinema optics.
Optically, the lens offers an 85mm focal length with an extremely fast T1.5 aperture, a T-stop rating rather than an f-stop, meaning the value reflects actual measured light transmission rather than a theoretical calculation, a distinction cinematographers rely on for consistent, predictable exposure across a matched set of lenses. This fast aperture allows for strong low-light performance and pronounced background separation, well suited to narrative filmmaking, interviews, and other productions where a shallow depth of field and classic portrait-length compression are desired.
As a manual cine lens, focus and aperture are controlled entirely by hand via geared focus and iris rings, designed to work smoothly with standard follow-focus systems and gear-driven accessories common in professional video production, rather than relying on autofocus or electronic aperture control. The de-clicked, stepless iris ring allows for smooth, silent aperture adjustments during recording, avoiding the audible clicks and visible exposure jumps that a traditional photo-lens aperture ring would introduce mid-shot.
Build quality centers on a robust housing typical of cine-style lenses, with consistent gear positioning and a standardized focus-throw design across Rokinon’s Cine DS lineup, allowing filmmakers to swap between focal lengths in the series without needing to significantly readjust follow-focus or matte box setups. The lens also typically includes clearly marked focus distance scales in both feet and meters on opposite sides of the barrel, a practical feature for focus pullers working from either side of the camera.
As a full-frame-compatible lens, the Rokinon 85mm T1.5 Cine DS delivers its full angle of view on full-frame Sony E-mount bodies while remaining compatible with Sony APS-C E-mount cameras at a narrower, telephoto-equivalent effective field of view.
