Lens detailNikon F mount with AF coupling and contacts; body autofocus motor supports compatible AF lenses. Current Japan specification supports compatible G/E/D, AF, AI-P, non-CPU AI and DX lenses with restrictions; non-CPU lenses use A/M exposure; non-AI, IX and F3AF excludedCompatible 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.
AutofocusAdvanced Multi-CAM 3500DX phase-detection module; 51 points including 15 cross-type and one central f/8-compatible point; -2 to +19 EV at ISO 100, 20°C; AF fine-tuning, dynamic nine/21/51 points, 3D tracking and auto-area AF. Live view uses contrast AF with AF-S/AF-F and face/wide/normal/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 vertical-travel focal-plane shutter; 1/8000 to 30 seconds in half or one-third stops, Bulb and Time; tested to 150000 cycles; X-sync 1/250 second, up to 1/320 with reduced guide number1/8000 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 detailFull DX: 6 fps JPEG/12-bit RAW or 5 fps 14-bit RAW. 1.3× crop: 7 fps JPEG/12-bit RAW or 6 fps 14-bit RAW; low-speed settings up to 6 fps; quiet release, mirror-up, self-timer and optional ML-L3 infrared remote modesMain 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 attached 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 i-TTL flash, guide number approximately 12 m at ISO 100, 20°C; commander mode, Auto FP with compatible external Speedlights and accessory shoeNo built-in flash; ISO 518 hot shoe, ISO 519 sync terminal and compatible external i-TTL Speedlights
