Rokinon 85mm T1.5 Cine DS Lens for Micro Four Thirds Mount

The Rokinon 85mm T1.5 Cine DS Lens for Micro Four Thirds Mount is a telephoto cinema prime lens built for Micro Four Thirds mirrorless cameras, delivering a 170mm full-frame-equivalent focal length and a 14.4-degree angle of view on MFT sensors. Its fast T1.5 maximum aperture offers excellent low-light performance and smooth background separation, making it well suited to portraits, interviews, and cinematic shots.

Optically, the lens is built from 9 elements in 7 groups, including an aspherical hybrid element that reduces spherical aberrations and distortion for clear, color-accurate footage. Rokinon’s Ultra Multi-Coating (UMC) minimizes flare and ghosting even in challenging lighting situations, such as backlit scenes or direct light sources, and an 8-blade iris diaphragm, adjustable from T1.5 to T22, contributes to smooth, rounded bokeh for isolating subjects with pleasing background blur.

As a fully manual cine-style lens, both focus and aperture are controlled directly on the barrel, with standard geared focus and iris rings shared across the entire Cine DS lineup, letting photographers swap lenses on the same rig without needing to reposition a follow-focus unit or iris motor. The aperture ring is de-clicked for smooth, stepless iris pulls during recording, and focus and T-stop scales are marked on both sides of the lens to accommodate focus pullers working from either side. The focus ring offers a wide, approximately 200-degree rotation for precise manual focus control, and the lens has a minimum focusing distance of 3.6 ft. (1.1m).

Build quality uses durable, all-metal construction built to withstand professional shooting environments, with a removable lens hood included to help control flare and protect the front element when shooting without a matte box. The lens accepts a 72mm filter thread and measures approximately 3.1 in. (78mm) in maximum diameter.

As part of Rokinon’s broader Cine DS series, the 85mm T1.5 is also available in Canon EF, Nikon F, and Sony E mounts, with color-matched optics and unified gear positions designed to minimize the need to adjust lighting, camera settings, or follow-focus rigging when switching between focal lengths in the same set.
