unterschied rf und ef Objektive?

EF lenses are for Canon EOS mirror reflex cameras and RF for EOS R Mirrorless cameras. Mirrorless cameras can be much closer to the sensor thanks to the lack of mirror lenses. For this reason, EF lenses can be easily adapted to RF-Mirrorless cameras by compensating for the distance, but otherwise it is not. In addition, RF lenses have more electronic connections and can transmit more information faster.
