Sensor detailFX CMOS with 36.3 million effective pixels USA/global or 36.35 million Japan, 37.09 million total; no optical low-pass filter. Modified IR-cut filter transmits four times more H-alpha light than D810. Nikon warns of red casts under near-infrared-rich lighting or with reflective subjects and does not recommend general photography.

Lens detailF mount with body AF coupling and contacts; G/E/D, other AF and AI-P lenses with restrictions; non-CPU AI lenses usable in A/M/M* with registered lens data, DX lenses use DX crop. Non-AI, IX and F3AF lenses excluded; USA G/H notation conflicts with Japan A/M/M*NIKKOR Z lenses; NIKKOR F lenses require a mount adapter and retain model-dependent restrictions
AutofocusAdvanced Multi-CAM3500FX phase detection with 51 points, 15 cross-type and 11 f/8-compatible points; -2 to +19 EV at ISO 100 equivalent, 20°C. AF-S/AF-C, fine-tuning, single-point, dynamic nine/21/51, 3D tracking, group-area and auto-area. Live view uses contrast AF-S/AF-F and face/wide/normal/tracking areas; current USA detection-range -1 EV entry conflicts with its own -2 EV sensitivity entry and Japan, while AF-A listings conflict with Japan modesHybrid phase/contrast detection, 493 single-point FX still positions, 3D tracking and subject detection including people, animals, birds and vehicles/aircraft. Maker sensitivity −7 EV or −9 EV with Starlight View, measured in AF-S at ISO 100, 20°C and f/1.2.
ShutterElectronically controlled vertical-travel focal-plane shutter, 1/8000 to 30 seconds, Bulb and Time; electronic front curtain in mirror-up mode. M* adds 4/5/8/10/15/20/30/60/120/180/240/300/600/900-second presets. X-sync 1/250 second, up to 1/320 with reduced flash rangeElectronic shutter only, with selectable sound and sensor shield; 1/32000 to 30 seconds, Bulb/Time and manual-mode extension to 900 seconds. Flash sync 1/200 or 1/250 second with reduced guide number at the higher speeds; compatible Auto FP up to 1/8000.
Burst detailApproximately 5 fps full FX or 5:4 and 6 fps DX or 1.2× crop on EN-EL15. DX reaches 7 fps with MB-D12 using batteries other than EN-EL15, or qualifying AC power; 1.2× remains 6 fps. Quiet continuous approximately 3 fps. M* continuous shooting at exposures of 4 seconds or longer removes the 100-shot limit, subject to battery/card capacityContinuous high-speed shooting up to 20 fps for full-resolution RAW. High-speed capture C15/C30 uses large FX or DX JPEGs, C60 requires large DX JPEGs and C120 requires small FX JPEGs (4128 × 2752). High-speed burst length varies by frame rate according to the current manual; these restricted JPEG modes are separate from the main continuous RAW figure. Pre-release capture available. Current manual restrictions take precedence over UK marketing prose and TechRadar's erroneous full-resolution 60 fps claim.
Stabilisation detailVR depends on attached lens; no sensor-shift stabilisationFive-axis sensor shift; lens VR supported, with Synchro VR up to 6 stops using NIKKOR Z 70–200mm f/2.8 VR S at the telephoto end under Nikon's CIPA conditions; electronic movie VR available
FlashBuilt-in i-TTL pop-up flash, guide number approximately 12 m at ISO 100, 20°C; commander mode, hot shoe, PC sync terminal and compatible Auto FP SpeedlightsNo built-in flash; ISO 518 hot shoe with compatible external i-TTL Speedlights
Exposure controlsP/S/A/M and long-exposure M*; 91000-pixel RGB matrix, centre-weighted, spot and highlight-weighted metering; ±5 EV compensation and exposure/flash/white-balance bracketing; HDR, interval timer and virtual horizon. Japan centre-weighted default 12 mm and spot range 2–20 EV differ from USA 8 mm and 0–20 EVP/S/A/M; ±5 EV still-image or ±3 EV movie compensation; matrix, centre-weighted, spot and highlight-weighted metering

Battery life detailEN-EL15, approximately 1200 CIPA shots. Original global announcement separately claims up to 3860 without built-in flash or immediate playback, and up to 10660 using body EN-EL15 plus grip EN-EL18a under those conditions; these are distinct from CIPA. Optional MB-D12 takes EN-EL15, EN-EL18/EN-EL18a with BL-5 or eight AA cellsEN-EL15c; CIPA monitor approximately 370 shots with power saving or 340 without; EVF 340 with power saving or 330 without. Nikon's separate continuous-shooting test gives approximately 2280 shots; movie battery claim approximately 85 minutes. EN-EL15b/15a provide fewer shots; optional MB-N12 takes two batteries.
ChargingExternal MH-25a charger; optional EH-5b AC adapter with EP-5B connectorUSB charging and power delivery with suitable optional cable/adapter; in-camera charging supports EN-EL15c/15b. MH-25a external charger appears in the technical accessory list; current UK included-accessory tiles do not list it, so verify regional package contents.
