The Canon Mount Adapter EF-EOS R allows you to use your existing EF and EF-S lenses on the modern EOS R system cameras. This adapter maintains full functionality, meaning you can continue relying on autofocus, image stabilization, and other essential lens features just as you would on a DSLR. Built for durability and reliability, it features metal lens mounts on both the front and back to ensure a secure connection. The construction is sealed against dust and moisture, which helps protect your gear when shooting in challenging environments. Weighing only 110 g and measuring 24 mm in length with a 71.2 mm diameter, this black adapter adds minimal bulk to your setup, making it a practical choice for photographers transitioning to mirrorless systems without needing to replace their entire lens collection. Please note that it is not compatible with RF, EF-M, or CN-E cinema lenses.
