The Nikon Z 30 Mirrorless with Z Dx 16-50mm Vr and Nikkor Z Dx 50-250mm Lenses uses a blazingly fast, nearly silent stepping motor for autofocus, and it performs brilliantly with Z series' Eye Af to keep the focus right where you want it. This set contains Lc-62B Snap-On Front Lens Cap, and Lf-N1 Rear Lens Cap.
