The Solid Camera PL Mount Adapter for Sony E Mount enables the use of a PL mount lens on a Sony E mount camera. The uni-directional lock ring prevents over-tightening and makes it easy to remove the lens. The adapter is compatible with ARRI shims for precise back focus adjustments. The entire mount can be adjusted to match the optical center of the sensor on your individual camera. The modular design allows for an optional migration to Micro Four Thirds or a dedicated screw-on mount.
