Canon RF to EF Adapter Tear down. Here we try to open up the adapter.
In this video I am trying to tear down a RF to EF adapter. The reason for this I am trying to figure out can a RF extender be mounter onto a EF lens as its very likely the RF extender is sharper than the EF MK3 extender is. It is possible to use 3rd party adapters to do this but the canon one is another storey.
