Lensbaby's mount adapters let you use your existing collection of SLR lenses on your new mirrorless camera body. Lensbaby’s rock solid, precision SLR to mirrorless mount
adapter allows you to mount Canon EF manual lenses, including all Canon EF Lensbaby lenses ever made, on your Canon R camera body.
Mount the adapter on your R mount body then mount your Canon EF Lensbaby on the front of the adapter and you’re all set. This combination lets your Lensbaby lenses
perform exactly the same on your mirrorless camera as you’ve grown accustomed to on your DSLR camera.
