Just saw a video on mathphorographer where he used this adapter on his Z9 with M lenses weighing less than 500 grams. Amazing quick and accurate focus. Not being a Nikon owner I was wondering if owning a Z7II would suffice with this type of adapter for autofocusing M lenses or is the Z9 the only way to go or are other Z cameras about as capable at quick and accurate AF with Z lenses.
