Metabones MBPL-EFR-BT1 Overview Mount ARRI PL-mount lenses on your Canon RF-Mount camera with this Metabones Camera Adapter. Aluminum body construction with chrome-plated mounts creates a precision fit with no gap, play, or wiggling. Felt material flocks the inside and bolsters optical quality by minimizing internal light reflections while a satin finish on the outside gives this adapter an OEM look. This adapter is designed to reach infinity focus while retaining the proper registration distance for maintaining optical quality when you are using CRC lenses or other lenses with floating elements. Because your camera's body cap cannot attach to the lens adapter, a rigid-and-removable locking dust cover is provided that allows you to disconnect your lens, leave the adapter mounted, and keep your camera's sensor protected during transportation. Additionally, a removable Arca-type tripod food is included for use with heavier lenses.
