This AF-P DX VR zoom supports D850 autofocus, camera-menu optical VR and focus shift. DX stills preserve its intended coverage; manual focus needs the camera awake.

- What was checked
- Viewfinder stills: AF sensor group, electronic manual focus, aperture, DX output, optical VR and focus-shift eligibility.
- Sources checked
The next source check for this pair is overdue. Next source check due .
Autofocus
SupportedAutofocus works across 70–300 mm; the lens falls in D850’s 45-cross-sensor group.
- Camera AF; no teleconverter.
- The zoom’s maximum-zoom aperture is slower than f/4; Nikon’s lens manual retains AF/rangefinder support beyond f/5.6.
- This is documented function, not a low-light tracking measurement.
Manual focus
LimitedManual focusing uses the electronic focus ring; it does not operate while the camera is off or asleep.
- Select camera M and wake the standby timer with a shutter half-press before turning the ring.
- D850 flashes its viewfinder focus indicator at the AF-P focusing-range limit.
Aperture control
SupportedAperture uses camera controls: f/4.5–22 at 70 mm and f/6.3–32 at 300 mm.
- Direct G-type CPU lens; P/S/A/M still exposure modes.
- Endpoint ranges are from the exact lens manual; intermediate zoom settings have their own maximum aperture.
Sensor coverage & crop
LimitedDX coverage gives a 1.5× field-of-view crop; DX Large stills are 5408 × 3600 pixels.
- Auto DX crop On selects DX automatically; with it Off, choose DX (24×16) for the intended image circle.
- Auto DX crop can be disabled, but wider areas may have dark or obscured edges.
- Large output selected; lower size settings record fewer pixels.
Stabilization
SupportedOptical VR is controlled by D850 Custom Setting d12 and activates with a shutter half-press.
- Exact VR model; enable d12 > Optical VR and wait for the viewfinder image to settle.
- For focus-shift sequences Nikon recommends tripod use with lens VR disabled.
- No D850-specific stop rating is established by this evidence.
Focus aids
SupportedThe lens meets D850’s AF-S/AF-P requirement for automated focus-shift capture; stacking needs external software.
- Camera AF and lens autofocus enabled; memory card inserted and clock set; release mode other than self-timer.
- Use the focus-shift menu; Nikon recommends tripod, A/M, fixed ISO and VR off.
- Excludes live view, movies, time-lapse, bracketing, Bulb/Time, HDR, multiple exposure and interval timer.
Not covered by the sources
- The lens manual predates later body support; its old body-exclusion list is not treated as a D850 prohibition. D850’s own AF-P compatibility table is decisive.
- The lens’s four-stop VR rating was measured on a DX body and is not claimed for the D850.
- Firmware-specific behavior, correction profiles, video and burst limits remain unverified.
- No hardware tests: focus accuracy, burst consistency, optical quality and stabilization effectiveness were not measured.
- Minimum supporting firmware and firmware-specific changes were not established; null versions do not mean universal support.
