About the Canon Mount Adapter EF-EOS R

Keep using your favorite Canon DSLR lenses with your EOS R mirrorless camera

There's been a lot of buzz surrounding the release of Canon's first full-frame mirrorless camera. Canon has already released a handful of high-quality RF-mount lenses for the EOS R, but if you already shoot with a Canon DSLR, you don't have to wait for more lens options to max out this camera's imaging potential. This low-profile mount adapter lets you keep using your existing EF and EF-S lenses with full functionality. The camera even recognizes when you attach an EF-S lens and will crop your images accordingly.

Product highlights:

  • allows Canon EF and EF-S lenses to be mounted on Canon EOS R mirrorless cameras
  • retains autofocus and image stabilization capabilities
  • dust- and moisture-resistant construction for shooting in adverse weather conditions
  • metal mounts on camera and lens sides for rugged flexibility
  • warranty: 1 year
  • Our 60-day money-back guarantee
  • MFR # 2971C002
