they don't have to, they can simply do it digitally, EFS lenses adapted on EOSRP are automatically set to crop mode that you cannot change .
for the lenses side they are giving you a free adapter with the cameras meanwhile
as for 18-45 and R10 a sample image taken at ISO12000 with the lens wide open isn't really bad
