PROMASTER AF Lens Adapter for Canon EF to RF

The ProMaster 5154 adapter connects Canon-type EF lenses to Canon RF mount cameras. It maintains AF and adds a nifty tripod quick release that is dovetail (arca-type) compatible. 

This lens adapter is built with an all-metal housing and metal lens mounts for long-lasting durability. It contains all of the proper electrical contacts to allow an EF / EF-S type lens to communicate with a Canon mirrorless camera via RF mount. This allows the AF system to work properly as well as metering and image stabilization.

In addition to adapting EF lenses to RF mount, the ProMaster 5154 adapter has a built-in tripod foot which is dovetail (arca-type) compatible. Now you can quickly connect your camera rig to a compatible tripod. Because the adapter itself makes the tripod connection you can remove both the lens and the camera body and quickly exchange them for others while the adapter remains mounted to the tripod. Additionally, a common 1/4"-20 threaded port can be found in the base of the adapter's foot. The tripod foot is also removable using a small tool that is included with the adapter, if you prefer.

A front and a rear dust cap are included to keep the adapter clean. These caps are also particularly helpful if you prefer to keep the adapter mounted to the camera without a lens attached or to the back of a lens sans camera.
