Canon Mount Adapter EF-EOS R

Three EF-to-RF adapters to fit the EOS R

Canon has announced three new EF-to-RF adapters along with the new RF lens mount, for present owners of Canon DSLR lenses. There's a bare bones adapter, another with a customizable control wheel to emulate the extra (3rd) knurled ring on the new RF lenses, and a third with support for drop-in filters.

Many users of exotic glass (some without any front filter thread at all, like the EF 11-24 F4L) will be thrilled to have an adapter with one-size drop-in circular polarizer or variable ND filters. In addition, you won't have to buy step-up rings or multiple size filters for your lenses with different front filter threads. Any EF lens can take advantage of the drop-in filter, with no size cost compared to the standard adapter.

The Mount Adapter EF-EOS R ($99.99, coming in October) Control Ring Mount Adapter EF-EOS R ($199.99, also coming in October) and Drop-in Filter Mount Adapter EF-EOS R ($299.99 with a CPL, $399.99 with a variable ND, available in March) are compatible with both EF and EF-S lenses.
