If there is specific lens you need I don't think I would hesitate to get the EF version and use the adapter.
I will as soon as i get my R6 and RF 800mm go to the field and try have nice sunny day and get handheld and with tripod shots with it and will make post about =) I should get atleast my R6 in couple weeks when the distribution here in finland starts, hopefully lens comes same time.
