Operating the Lens
Focus Control
The Xeen 35mm T1.5 lens features a manual focus ring with a long focus throw (200 degrees) for precise adjustments. Rotate the focus ring to achieve sharp focus on your subject. The focus distance markings are clearly visible on the lens barrel in both feet and meters.
Aperture (T-Stop) Control
