The Z9 has a built-in vertical grip, but the other Z System cameras do not. Here are some solutions:
Z6, Z7, Z6II, Z7II, and Z8 Vertical Battery Grip
- Nikon original for Z6/Z7 is MB-N10 (review here)
- Nikon original for Z6II/Z7II is MB-N11 (review here)
- Nikon original for Z5II and Z6III (also works with Z6II/Z7II) is MB-N14 (better fit for the Z6/Z7 size bodies)
- Nikon original for Z8 is MB-N12
- Mcoplus BG-Z6Z7 is an MB-N10 replacement at a lower cost
- Mcoplus BG-Z6II/Z7II is an MB-N11 replacement at a lower cost
Z5II, Z6 II, Z6III, Z7 II, Z8, and Z9 Remote Grip
- MC-N10 Remote Grip (for video use on tripod or gimbal)
The Zf, Zfc, Z30, Z50, and Z50II do not support a vertical grip.
