Nikon's compact retractable DX kit zoom for Z-mount, the standard bundle lens for Z50 and Zfc.
The Nikon Z DX 16-50mm f/3.5-6.3 VR is the standard kit lens for Nikon's APS-C Z-mount cameras including the Z50 and Zfc. With a retractable design that collapses to just 32mm thick, it makes Z50 and Zfc bodies remarkably compact for a mirrorless system.
Optical quality is decent for a kit lens with good centre sharpness improved by the retractable design which allows for a more complex optical formula. VR provides approximately 4.5 stops. The stepping motor delivers quiet AF for video. Build is lightweight plastic at just 135g.
Nikon Z mount in DX format, 46mm filter thread. One of very few native DX Z-mount lenses. F-mount DX lenses can be adapted via the FTZ adapter but are physically much larger. The Z DX 50-250mm f/4.5-6.3 VR is the natural telephoto companion.
Cheap used. Check the retractable mechanism for smooth operation and the VR stabilisation. The lens is adequate as a starter but most users will want something faster or longer range eventually. The limited DX Z-mount ecosystem means alternatives are scarce.
