Rokinon 85mm T1.5 Cine DSX camcorder lens for Micro Four Thirds

Portrait telephoto for Micro Four Thirds

The Rokinon 85mm T1.5 Cine DSX is a fixed focal-length lens built for Micro Four Thirds camera systems. Its 85 mm perspective suits portrait and telephoto work, while the T1.5 aperture gathers ample light for indoor or evening shoots. Manual focus and a declicked aperture ring give the operator full creative control over exposure and depth of field.

Mount and control integration

The lens mounts directly to any Micro Four Thirds body without adapters, freeing the front of the rig for matte boxes or follow-focus gears. A 140-degree focus throw provides the long rotation needed for precise, repeatable pulls during narrative takes. Standardised gear positions on focus and iris rings match common cinema accessories, reducing setup time on set.

Aperture headroom and optical limits

At T1.5 the lens delivers shallow depth of field and usable exposure in low-light scenes, while the nine-element, seven-group design controls aberrations across the frame. Stopping down deepens focus for interview or documentary setups where subject distance varies. The fixed 85 mm field of view cannot widen for establishing shots, so a second lens is required for broader coverage.
