Lens detailAutofocus with AF-S and AF-I motor-equipped lenses; no body autofocus motor. Other compatible AF lenses require manual focusing; non-CPU lenses require manual exposure without metering; IX and F3AF lenses unsupportedNIKKOR Z FX and DX lenses; FX lenses have a DX field-of-view crop. F-mount NIKKOR lenses require an adapter and retain model-dependent restrictions.
AutofocusMulti-CAM 530 phase-detection module; three selectable autofocus areas; -1 to +19 EV at ISO 100 equivalent, 20°C; AF-S/AF-C/AF-A, single-area, dynamic-area and closest-subject-priority dynamic-area modes; AF-assist illuminatorHybrid phase/contrast detection; 209 single-point or 231 auto-area positions, nine subject types, 3D tracking and AF-A. Nikon's −9 EV sensitivity uses AF-S, ISO 100, an f/1.2 lens and 20°C.
ShutterCombined CCD electronic and mechanical shutter; 1/4000 to 30 seconds in one-third stops, Bulb and Time with optional ML-L3 remote; flash sync 1/500 secondMechanical, electronic front-curtain and electronic; 1/4000 to 30 seconds plus Bulb/Time, extendable to 900 seconds in manual mode. Flash sync up to 1/250 second with reduced guide number above 1/200; Auto FP supported.
Burst detailApproximately 2.5 fps; self-timer and optional ML-L3 delayed or immediate infrared remote releaseExtended continuous shooting approximately 11 fps, or 15 fps silent; ordinary high approximately 5.6 fps, rising to 9.7 fps silent without RAW. C15/C30 high-speed capture with pre-release capture reaches 30 fps for JPEGs, not RAW.
Stabilisation detailOptical VR depends on the attached lens; no sensor-shift stabilisation. The pictured original 18–55mm ED II kit lens has no VRNo sensor-shift stabilisation; optical stabilisation depends on a VR lens. Electronic video VR adds a crop.
