• Lift up your lens.
• Align the little red mark on the lens with the red mark on your camera.

That’s it. The lens is now securely attached.

Tutorial 2/2: How to Use an EF Lens on Your Canon R6 Mark II

In this guide, I'm going to break down how to use an EF lens on your Canon R6 Mark II, which is a mirrorless camera with an RF mount.

Why You Need an Adapter

Here I have a Canon 60D, which is a crop sensor camera and a Canon EF 50mm 1.8 lens. This is a great, affordable fast lens and I love using it on my Canon 60D. Even though it was a crop sensor lens, which made it more like 85mm, it produced great sharp images.

When I got my Canon R6 Mark II, I wanted to continue using this lens on the new camera, but I couldn't because of the mount.

EF lenses do not work out of the box on mirrorless cameras.

What you need to make your EF lenses work on your Canon R6 Mark II is a mount adapter, EF-EOS R. This adapter will allow you to take any EF lens and use it on your mirrorless cameras.

The EF-EOS R Mount Adapter

The adapter that I have is the official Canon EF-EOS R mount adapter. I don't like any off-brands and I like to go directly to Canon.

The adapter has two parts:

• The part that attaches to the camera
• The part where the lens goes (at the top)

You can unscrew the top to attach the EF lens. There is a red mark and a little notch on the adapter.

How to Attach the Lens to the Adapter

• Unscrew the top of the adapter and open it up.
• Remove the cap from your EF lens.
• Align the red mark on the lens with the red mark on the adapter.
• Tighten it until you hear the click.

The lens is now attached to the adapter.

How to Attach the Adapter to the Camera

• Remove the current lens on the camera by pressing the release button on the side and unscrewing it counterclockwise.
• Put a cap on the camera body to protect it.
• On the adapter, unscrew the back cap.
• Align the red mark on the adapter with the red mark on the camera.
• Screw the adapter on until you hear a click.

Done.

You are now ready to use your EF lenses on your Canon R6 Mark II.
