How to Set Up the Nikon FTZ II Adapter on Z Series Cameras

Quick answer

Mount the Nikon FTZ II Adapter the same way you would a lens: align the white dot on the adapter with the white dot on the camera mount, twist until it clicks, then attach your F-mount lens. Before shooting, update your camera body to the latest firmware, set the lens to autofocus, and confirm the adapter is fully seated. The FTZ II works with Nikon Z mirrorless bodies, including the Z9 and Z6, and gives you access to a wide range of Nikon F-mount lenses.

Why the FTZ II exists and what it changes

Nikon Z cameras use the Z mount, which has a short 16mm flange distance and a large diameter. F-mount lenses were designed for a longer flange distance, so they cannot sit close enough to the sensor without an adapter. The FTZ II adds the correct spacing and passes through electronic communication so the camera can control autofocus and aperture on compatible lenses. It is not a teleconverter and it does not change focal length or aperture; it simply makes F-mount glass usable on Z bodies.

What you need before you start

Have your Nikon Z camera, the FTZ II adapter, a charged battery, and a compatible F-mount lens. A body cap or lens cap is useful if you are swapping in a dusty environment. You will also want a way to check firmware: either the camera's setup menu or Nikon's software. If your lens is a screw-drive AF type that relies on a camera-body motor, autofocus will not work through the FTZ II; those lenses become manual focus only. That is a lens limitation, not an adapter fault.

Mounting order and physical checks

Attach the adapter to the camera first, then the lens. This reduces the chance of twisting the lens mount while the adapter is loose. Line up the white alignment dot on the adapter with the white dot on the camera body, press gently, and rotate until you feel a solid click. Then line up the lens dot with the adapter dot and rotate until it clicks. Give the lens a light tug to confirm it is locked. If you feel resistance, stop and recheck alignment rather than forcing it.

Firmware and autofocus settings that matter

Firmware is the most common reason an FTZ II behaves unexpectedly. Check your camera body firmware and update if a newer version is available; Nikon occasionally improves adapter and lens compatibility through body updates. After updating, set the lens to AF, then choose an autofocus area mode that suits your subject. For still subjects, single-point AF with AF-S gives predictable results. For moving subjects, use continuous AF with a wider area. If autofocus hunts, try a different AF area mode before assuming the adapter is faulty.

Testing and troubleshooting

After mounting, take a few test shots at different apertures and focus distances. Check that the camera reports the correct aperture and that autofocus responds. If the camera shows an F-- aperture error or will not focus, remove the adapter and lens, inspect the contacts for dust or smudges, and remount. If the problem persists, try another F-mount lens to isolate whether the issue is the lens or the adapter. A lens that is not on Nikon's compatibility list may work in manual focus only.

Which Z bodies pair well with the FTZ II

The FTZ II is designed for Nikon Z mirrorless cameras. The Z9 is a flagship full-frame body with a 45.7MP BSI CMOS sensor and EXPEED 7 processor, and it handles F-mount glass well for detail-oriented stills and high-resolution video. The Z6 is an all-around FX-format body with a 24.5MP BSI CMOS sensor and EXPEED 6 processor, and it is a lighter option for everyday use. Both accept the FTZ II, so your choice depends on resolution, speed, and budget rather than adapter compatibility.

FTZ II setup steps

1. Update camera firmware first: Check the camera's firmware version in the setup menu and update if a newer version is available. Nikon sometimes improves lens and adapter compatibility through body firmware. Checkpoint: the camera should show the latest firmware before you mount anything.
2. Attach the adapter to the camera body: Align the white dot on the FTZ II with the white dot on the Z mount, press gently, and rotate until it clicks. Do not attach the lens first. Checkpoint: the adapter should be locked with no play before you add a lens.
3. Mount your F-mount lens: Line up the lens dot with the adapter dot and rotate until it clicks. Give a light tug to confirm it is seated. Checkpoint: if it does not click, stop and recheck alignment rather than forcing it.
4. Set the lens to autofocus and choose an AF mode: Switch the lens to AF, then pick single-point AF for stills or continuous AF with a wider area for moving subjects. If AF hunts, try a different area mode. Checkpoint: confirm the camera reports the correct aperture and focuses on a test subject.
5. Test and troubleshoot: Shoot at several apertures and distances. If you see an F-- error or no focus, remove the adapter and lens, inspect contacts, and remount. Try a second F-mount lens to isolate the issue. Checkpoint: if a screw-drive AF lens will not autofocus, it is a lens limitation, not an adapter fault.

Products used in this guide

• Nikon FTZii Adapter: The Nikon FTZ II Adapter is designed for use with Nikon mirrorless cameras and allows you to expand your lens compatibility while maintaining a seamless connection between compatible lenses and the camera body. This is the core accessory for the steps above; without it, F-mount lenses cannot be mounted on a Z body.
• Nikon Z9 with FTZ II mount adapter Mirrorless Camera: The Nikon Z9 is a flagship full-frame mirrorless camera with a 45.7MP BSI CMOS sensor and EXPEED 7 processor, capable of shooting up to 120 fps and recording up to 8K video. If you pair the FTZ II with a high-resolution body like the Z9, F-mount lenses benefit from the camera's fast processing and detailed sensor.
• Nikon Z6 Body with FTZ Mount Adapter: The Nikon Z6 is an all-around FX-format mirrorless camera with a 24.5MP BSI CMOS sensor and EXPEED 6 processor, and it uses the Z mount with a 16mm flange distance. The Z6 is a lighter, lower-cost Z body that still accepts the FTZ II, making it a practical starting point for using existing F-mount lenses.
