making the migration ADAPTORS EASE THE WAY!
Swapping from a DSLR to a mirrorless camera system used to be a major decision with big financial consequences. Who wants to have to sell their entire system of camera bodies and lenses and start again? Canon and Nikon have both thought of that, so both the Nikon Z series and the Canon EOS R can use existing Nikon and Canon DSLR lenses via inexpensive lens adaptors, and with no restriction on autofocus or exposure. Now if you want to try a mirrorless camera, you can just buy a new body and still use all your existing lenses.
