Lens detailNikon F mount with autofocus coupling and contacts; body autofocus motor. G/D AF Nikkor, other compatible AF lenses and AI-P supported with restrictions; non-CPU lenses only in M with no exposure meter. Current US page also claims AI metering and A mode, conflicting with its own non-CPU entry and original manual; original manual compatibility controls. E-type lenses incompatibleNIKKOR Z lenses; NIKKOR F lenses require a mount adapter, with model-dependent functional restrictions
AutofocusNikon Multi-CAM900 TTL phase detection; five selectable areas, single-area or dynamic AF with closest-subject priority; single/continuous servo and predictive tracking; -1 to +19 EV at ISO 100, 20°C; AF-assist illuminatorHybrid phase/contrast detection; 273 single-point or 299 auto-area positions in FX stills; 3D tracking, nine subject types and AF-A automatic AF-S/AF-C selection. Nikon's −10 EV sensitivity uses AF-S, ISO 100, an f/1.2 lens and 20°C.
ShutterElectronically controlled vertical-travel focal-plane shutter, 1/4000 to 30 seconds plus Bulb; flash synchronisation up to 1/180 second. Optional mirror anti-shock delay; cleaning mirror lock is distinctMechanical, electronic front-curtain and electronic shutter; 1/8000 to 30 seconds plus Bulb/Time, extendable to 900 seconds in manual mode; flash sync at 1/200 second or slower and Auto FP support
Burst detailApproximately 3 fps under Nikon's manual-focus, manual-exposure, 1/250-second-or-faster test. Manual buffer up to six frames or four RAW images; with noise reduction enabled, three frames or two RAW images; single-frame and self-timer modesOrdinary continuous high approximately 7.8 fps mechanical, 9.4 fps electronic front-curtain or 10 fps silent. Extended high approximately 14 fps, or 15 fps silent, with JPEG-only restrictions at the highest extended rate. C15/C30 high-speed frame capture supports pre-release capture; main 30 fps is electronic-shutter JPEG normal, not RAW.
Stabilisation detailOptical VR depends on the attached lens; no sensor-shift stabilisationFive-axis sensor shift; maker claim up to 7.5 stops at the centre or 6 at the periphery under CIPA 2024 using NIKKOR Z 24–120mm f/4 S at the telephoto end in NORMAL mode. Focus Point VR has compatible-lens and focus-mode restrictions.
