Lens detailBody AF motor supports compatible screw-drive lenses. Supported non-CPU AI lenses permit aperture-priority and manual exposure, with colour matrix metering when lens data is entered. 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 3500DX; 51 points including 15 cross-type, dynamic 9/21/51-point modes and 3D tracking; AF fine-tuningHybrid 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.
Shutter1/8000 to 30 seconds and Bulb; standard flash sync 1/250 second, with 1/320 at reduced flash range; Quiet release mode; shutter tested to 150000 cyclesMechanical, electronic front-curtain and electronic; 1/4000 to 30 seconds plus Bulb/Time, extendable to 900 seconds in manual mode.
