Other Accessories
At the time of writing, the following accessories were available for the D7100.
Power
sources
• Rechargeable Li-ion Battery EN-EL15 (0 22, 24): Additional EN-EL15 batteries are
available from local retailers and Nikon-authorized service representatives.
• Battery Charger MH-25 (0 22): Recharge EN-EL15 batteries.
• Multi-Power Battery Pack MB-D15: The MB-D15 is equipped with a shutter-release
button, A AE/AF lock button, multi selector, and main- and sub-command
dials for improved operation when taking photographs in portrait (tall)
orientation.
When attaching the MB-D15, remove the camera MB-D15 contact
cover.
• Power Connector EP-5B, AC Adapter EH-5b: These accessories can be used to power
the camera for extended periods (EH-5a and EH-5 AC adapters can also be
used).
The EP-5B is required to connect the camera to the EH-5b; see page 311
for details. Note that when the camera is used with an MB-D15, the EP-5B must
be inserted into the MB-D15, not the camera. Do not attempt to use the
camera with power connectors inserted into both the camera and MB-D15.
Filters
• Filters intended for special-effects photography may interfere with autofocus
or the electronic rangefinder.
• Use C-PL or C-PL II circular polarizing filters.
Polar-brand linear polarizing filters
can not be used.
• Use NC filters to protect 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/C-PL II, ND2S, ND4,
ND4S, ND8, ND8S, ND400, A2, A12, B2, B8, B12). See the filter manual for
details.
Viewfinder
eyepiece
accessories
• DK-20C Eyepiece Correction Lenses: Lenses are available with diopters of –5, –4, –3,
–2, 0, +0.5, +1, +2, and +3 m
–1
when the camera diopter adjustment control is
in the neutral position (–1 m
–1
).
Use eyepiece correction lenses only if the
desired focus can not be achieved with the built in diopter adjustment control
(–2 to +1 m
–1
).
Test eyepiece correction lenses before purchase to ensure that
the desired focus can be achieved.
The rubber eyecup can not be used with
eyepiece correction lenses.
• Magnifying Eyepiece DK-21M: The DK-21M magnifies the view through the
viewfinder by approximately 1.17× (50 mm f/1.4 lens at infinity; –1.0 m
–1
) for
greater precision when framing.
• Magnifier DG-2: The DG-2 magnifies the scene displayed in the center of the
viewfinder for greater precision during focusing.
Eyepiece adapter required
(available separately).
• Eyepiece Adapter DK-22: The DK-22 is used when attaching the DG-2 magnifier.
• Right-Angle Viewing Attachment DR-6: The DR-6 attaches at a right angle to the
viewfinder eyepiece, allowing the image in the viewfinder to be viewed at
right angles to the lens (for example, from directly above when the camera is
horizontal).
