Canon EF lenses on Nikon Z: the Viltrox EF-Z2 speed booster

Viltrox's EF-Z2 is a 0.71x speed booster, not a plain adapter: it keeps native autofocus and stabilisation, supports Nikon face/eye-detection AF, widens the field of view by 0.71x and gains about a stop of light. Viltrox names the Z6, Z7 and Z50 as target bodies.
