261Technical Notes
Power sources • 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” (0 271) 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.

• 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.
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.
