Other Accessories

Power sources
  • EN-EL15a Rechargeable Li-ion Battery (0 Battery Info): Additional EN-EL15a batteries are available from local retailers and Nikon service representatives. EN-EL15c/EN-EL15b/EN-EL15 batteries can also be used. Note, however, that you will not be able to take as many pictures on a single charge using EN-EL15 batteries.
  • MH-25a Battery Charger: The MH-25a can be used to recharge EN-EL15a batteries. MH-25 battery chargers can also be used.

  • MB-D18 Multi-Power Battery Pack (0 Optional MB-D18 Battery Packs, f10: Assign MB-D18 Buttons, MB-D18 Battery Type, Battery Order): The MB-D18 is equipped with a shutter-release button, Fn button, AF-ON button, multi selector, and main- and sub-command dials for improved operation when taking photographs in portrait (tall) orientation. When attaching the MB-D18, remove the camera MB-D18 contact cover. A BL-5 battery-chamber cover and an MH-26a or MH-26 battery charger are required when using EN-EL18c batteries. EN-EL18b, EN-EL18a, and EN-EL18 batteries can also be used. The maximum frame advance rate varies with the battery type; the figures below are the average maximum frame rates available with continuous-servo AF, manual or shutter-priority auto exposure, a shutter speed of 1/250 s or faster, and other settings at default values.

    Battery type Release mode
    Ch Cl
    EN-EL15a/AA 7 fps 1– 6 fps
    EN-EL18c 9 fps 1–8 fps

    The number of pictures that can be taken in a single burst also varies with the power source; for more information, see “Buffer Capacity” (0 Buffer Capacity).

  • EP-5B Power Connector, EH-5c and EH-5b AC Adapters: These accessories can be used to power the camera for extended periods. The EP-5B is required to connect the camera to the EH-5c/EH-5b; see “Attaching a Power Connector and AC Adapter” (0 Attaching a Power Connector and AC Adapter) for details. Note that when the camera is used with an MB-D18, the EP-5B must be inserted into the MB-D18, not the camera. Do not attempt to use the camera with power connectors inserted into both the camera and MB-D18.
Filters
  • Filters intended for special-effects photography may interfere with autofocus or the electronic rangefinder.
  • The D850 cannot be used with linear polarizing filters. Use the C-PL or C-PLII circular polarizing filter instead.
  • Neutral Color (NC) filters are recommended for protecting the lens.
  • To prevent ghosting, use of a filter is not recommended when the subject is framed against a bright light, or when a bright light source is in the frame.
  • Center-weighted metering is recommended with filters with exposure factors (filter factors) over 1 × (Y44, Y48, Y52, O56, R60, X0, X1, C-PL, ND2S, ND4, ND4S, ND8, ND8S, ND400, A2, A12, B2, B8, B12). See the filter manual for details.
Wireless transmitters (0 Ethernet and Wireless Networks)
  • WT-7 Wireless Transmitter: Use the WT-7 to upload pictures over a wireless network, to control the camera from a computer running Camera Control Pro 2 (available separately), or to take and browse pictures remotely from a computer or smart device.

  • USB Cable Gaskets and Connector Covers: Use a UF-4 connector cover for USB cables and UF3-RU14 USB cable gasket to help prevent accidental disconnections. Before connecting the cable, attach the UF-4 at the camera end and the UF3-RU14 at the end that connects to the wireless transmitter.

    UF-4 (attaches to connector for camera)

    UF3-RU14 (attaches to connector for WT-7)

Note: A wireless network and some basic network knowledge is required when using a wireless transmitter. Be sure to update the wireless transmitter software to the latest version.

Wireless remote controllers (0 Wireless Remote (WR) Options, Assign Remote (WR) Fn Button)
  • WR-R10 Wireless Remote Controller/WR-T10 Wireless Remote Controller: When a WR-R10 wireless remote controller is attached to ten-pin remote terminal using a WR-A10 adapter, the camera can be controlled wirelessly using a WR-T10 wireless remote controller. The WR-R10 can also be used to control radio-controlled flash units.

  • WR-1 Wireless Remote Controller: WR-1 units are used with WR-R10 or WR-T10 wireless remote controllers or with other WR-1 remote controllers, with the WR-1 units functioning as either transmitters or receivers. For example, a WR-1 can be attached to the ten-pin remote terminal and used as a receiver, allowing the shutter to be released remotely by another WR-1 acting as a transmitter. A WR-A10 WR adapter is required when using the WR-R10.

Note: Be sure the firmware for the WR-R10 and WR-1 has been updated to the latest version. For information on firmware updates, see the Nikon website for your area.

Viewfinder eyepiece accessories
  • DK-19 Rubber Eyecup: The DK-19 makes the image in the viewfinder easier to see, preventing eye fatigue.
  • DK-17C Diopter-Adjustment Viewfinder Lens: To accommodate individual differences in vision, viewfinder lenses are available with diopters of –3, –2, 0, +1, and +2 m–1. Use diopter adjustment lenses only if the desired focus cannot be achieved with the built-in diopter adjustment control (–3 to +1 m–1). Test diopter adjustment lenses before purchase to ensure that the desired focus can be achieved.
  • DK-17M Magnifying Eyepiece: The DK-17M magnifies the view through the viewfinder by approximately 1.2 × for greater precision when framing.
  • DG-2 Eyepiece Magnifier: The DG-2 magnifies the scene at the center of the viewfinder for more accurate focus. DK-18 eyepiece adapter (available separately) required.
  • DK-18 Eyepiece Adapter: The DK-18 is used when attaching the DG-2 magnifier or DR-3 right-angle viewing attachment to the D850.
  • DK-14 Antifog Finder Eyepiece/DK-17A Antifog Finder Eyepiece: These viewfinder eyepieces prevent fogging in humid or cold conditions.
  • DK-17F Fluorine-Coated Finder Eyepiece: The protective glass features an easy-to-clean fluorine coating on both surfaces.
  • DR-5 Right-Angle Viewing Attachment/DR-4 Right-Angle Viewing Attachment: The DR-5 and DR-4 attach to the viewfinder eyepiece at a right angle, allowing the image in the viewfinder to be viewed from above when the camera is in the horizontal shooting position. The DR-5 supports diopter adjustment and can also magnify the view through the viewfinder by 2 × for greater precision when framing (note that the edges of the frame will not be visible when the view is magnified).
HDMI cables (0 Viewing Photographs on TV)
HC-E1 HDMI Cable: An HDMI cable with a type C connector for connection to the camera and a type A connector for connection to HDMI devices.
Software

Camera Control Pro 2: Control the camera remotely from a computer and save photographs directly to the computer hard disk. When Camera Control Pro 2 is used to capture photographs directly to the computer, a PC connection indicator (c) will appear in the control panel.

Note: Use the latest versions of Nikon software; see the Nikon website for your region for the latest information on supported operating systems. At default settings, Nikon Message Center 2 will periodically check for updates to Nikon software and firmware while you are logged in to an account on the computer and the computer is connected to the Internet. A message is automatically displayed when an update is found.

Body caps
BF-1B Body Cap/BF-1A Body Cap: The body cap keeps the mirror, viewfinder screen, and image sensor free of dust when a lens is not in place.
