Compatibility of Ensō lenses

ARRI Ensō lenses are equipped with the LPL (Large Positive Locking) lens mount. A wider diameter and shorter flange focal depth allow LPL lenses to be small and lightweight, with a fast T-stop and pleasing bokeh—a combination of features that would not be possible with the old PL lens mount. Careful testing is required when using Ensō Vintage Elements with third-party LPL mounts.
