Canon EF Mount. We carry Rokinon Xeen lenses in several different mounts, with this one being the Canon EF-mount version.

Full-Frame Normal Range. The Rokinon Xeen 50mm T1.5 offers full-frame coverage, giving you a budget-friendly normal-range cinema lens. Its fast T1.5 aperture allows the flexibility to shoot in low light, not to mention depth-of-field control. Keep in mind sensor crop-factors do apply when using smaller than full-frame formats.

4K Resolving Power. Keeping with the market trend, the Xeen lenses support 4K+ capture. Optics are largely the same as the Rokinon Cine DS line of lenses. However, additional multi-coatings have been applied to ensure consistent and accurate color when switching lenses to another in the Xeen line.

True Cinema Lens. Yes, it’s true the Xeen lenses share similarities with the Cine DS lenses. But where they differ is in the build and performance you’d except from a true cinema lens. Their aluminum housing with calibrated, 0.8 pitch geared focus and iris rings offer buttery-smooth operation. Dual scale markings, standardized ring position, and uniformity in physical size across the lineup enable consistency for rigging out your setup with follow focuses and matte boxes.

Fully Manual. This lens provides no electronic communication with the camera. All aperture and focus adjustments must be made manually on the lens itself. The aperture selected will not be displayed on the camera, and it won’t show up in the EXIF data.
