I have an R5 and the adapter on order (don't expect to get it very soon)....I am going with my EF lenses to start as I have all I need from 16 to 600mm. At this moment I do not know if I will purchase any more EF lenses or any RF lenses for that matter. I admit that I am intrigued by the 800mm f/11 so if I try any RF lenses it would probably be that one.

If there is specific lens you need I don't think I would hesitate to get the EF version and use the adapter.
