Lens detailAutofocus supported with AF-P lenses and type E/G AF-S lenses; no body autofocus motor for screw-drive lenses. Nikon's specification is narrower than Photography Blog's AF-S/AF-I descriptionCompatible F-mount lenses include G/E/D, other supported AF, P and AI non-CPU lenses with restrictions; DX lenses use a cropped image area. Non-AI, IX and F3AF lenses unsupported.
AutofocusMulti-CAM 1000; 11 phase-detection points including one cross-type; -1 to +19 EV at ISO 100, 20°C; AF-S/AF-C/AF-A, single-point, dynamic, auto-area and 11-point 3D tracking. Contrast-detection live view supports face, wide, normal and subject-tracking areasViewfinder Multi-CAM 20K phase detection with 153 points, 99 cross-type and 55 user-selectable; 15 support f/8. Live view uses contrast detection with face, wide, normal, pinpoint and tracking modes. Review references to a Multi-CAM 3500 module are incorrect.
ShutterElectronically controlled focal-plane shutter; 1/4000 to 30 seconds in one-third stops, Bulb and Time; flash sync 1/200 second1/8000 to 30 seconds, Bulb and Time; mechanical focal-plane and electronic front-curtain options; flash sync 1/250 second with compatible Auto FP support; electronic silent live-view modes
Burst detailApproximately 5 fps with manual focus, S/M exposure, 1/250 second or faster and other settings at defaultsMain 9 fps requires optional MB-D18 grip, EN-EL18b battery and BL-5 cover; body with EN-EL15-series battery reaches 7 fps. Full-resolution silent Mode 1 reaches 6 fps. Brief silent Mode 2 reaches 30 fps for at most three seconds with fixed focus/exposure and 3600 × 2400 DX JPEG Normal files; this restricted mode is not the headline continuous rate.
Stabilisation detailOptical VR depends on the lens; no sensor-shift stabilisationNo sensor-shift stabilisation; optical VR depends on the attached lens. Electronic movie vibration reduction available with mode restrictions.
FlashBuilt-in pop-up flash; guide number approximately 7 m at ISO 100, 20°C, or 8 at manual full output; accessory shoeNo built-in flash; ISO 518 hot shoe, ISO 519 sync terminal and compatible external i-TTL Speedlights
Exposure controlsP/S/A/M, Auto, flash-off Auto, scene and special-effects modes; beginner Guide mode; 420-pixel RGB metering with matrix, centre-weighted and spot modes; ±5 EV compensation; Active D-Lighting on/offP/S/A/M; ±5 EV compensation; 180K-pixel RGB metering sensor, unlike Photography Blog's erroneous 91K-pixel narrative
