B4 To Canon EOS R Lens Mount Adapter – Fit 2/3" Broadcast Lens On Full Frame Mirrorless

Adapt your professional 2/3\ B4 broadcast lens to shoot on a Canon EOS R full frame mirrorless camera with this open box adapter.

It's essentially brand new and has never been used – it just might not have the original retail packaging.

This is a generic adapter, model B4 EOS R, that lets you twist on your B4 mount lens to the RF mount of the EOS R.

It's a simple, solid ring with no glass elements, so it's just a mechanical connection.

Made in China, it opens up a whole new world of lens possibilities for your video or photo work.

If you have high-end Fujinon or Canon B4 glass sitting around, this adapter lets you put it to work on a modern mirrorless body.
