I just got it in Ill take a few test shots I noticed its manual focus which is fine for shooting at night set at eternity and go..... Ill be back in a few to post some test shotsMy older F mount version didn't work on the Z7 with FTZ unless I taped off the electrical contacts so that it acts like a dumb lens. It was bought several years ago and worked ok on D7100 and D500. Obviously the newer Z mount version has a better chance. Optically the lens was OK on DX, fine for the price. Corners obviously weaker on FX but whether that mattered is up to you.
