- What was checked
- Stills: manual focus assistance, aperture-ring setup, exposure, stabilization and image area through FTZ II.
- Sources checked
The next source check for this pair is overdue. Next source check due .
Autofocus
UnsupportedFTZ II does not autofocus this AF D lens.
- Use manual focus. This is the AF 50mm f/1.8D, not an AF-S model.
Focus aids
SupportedManual focusing retains electronic rangefinding; magnification and peaking are available.
- Turn the lens focus ring in MF; enable peaking if wanted.
- Verify difficult subjects in magnified view.
Aperture control
SupportedSet and lock the ring at f/22; the camera then selects the shooting aperture, including f/1.8.
- Set f/22 before mounting; use the camera sub-command dial in A or M.
Exposure metering
SupportedExposure metering and P/S/A/M remain available despite manual focusing.
- Keep the aperture ring at f/22; use the CPU contacts through FTZ II.
Stabilization
SupportedThe Z8 can stabilize this adapted CPU lens in three axes.
- Enable camera vibration reduction; no combination-specific stop benefit is asserted.
Sensor coverage & crop
SupportedThe FX lens can use the Z8 full-frame image area.
- Select FX (36x24) for stills.
Not covered by the sources
- No minimum firmware versions or exact-version combination test is specified in the consulted evidence.
- Focus-confirmation accuracy and stabilization effectiveness were not measured for this exact combination.
- The Nikon product page has a contradictory G-type field; classification follows its original D-type lens manual.
