■Nikon GP-1 global positioning system (GPS) device.This accessory attaches to
the accessory shoe on top of the Nikon D90 and captures latitude, longitude, and
altitude information, which is imprinted in a special data area of your image files.
The “geotagging” data can be plotted on a map in Nikon ViewNX or other soft-
ware programs. I’ll explain more about this feature in Chapter 7.
■AC adapter EH-5a. There are several typical situations where this AC adapter for
your D7000 can come in handy: when you’re cleaning the sensor manually and
want to totally eliminate the possibility that a lack of juice will cause the fragile
shutter and mirror to spring to life during the process; when in the studio shoot-
ing product photos, portraits, class pictures, and so forth for hours on end; when
using your D7000 for remote shooting as well as time-lapse photography; for exten-
sive review of images on your standard-definition or high-definition television; or
for file transfer to your computer. These all use prodigious amounts of power, which
can be provided by this AC adapter. (Beware of power outages and blackouts when
cleaning your sensor, however!)
■Multi-power battery pack MB-D11. Lots of photographers consider this battery
pack/vertical grip to be an essential item (I’m going to cover it in detail later in this
book), but you must buy it as an extra. The price is reasonable at less than $250.
Unfortunately, it is delivered “bare,” with no extra power sources at all. You’ll need
to purchase AA batteries (alkalines or rechargeables) for the supplied AA battery
tray, or have an extra EN-EL15 battery to use this accessory. (I toldyou that you’d
need that extra battery.)
■DR-6 right-angle viewer. Fastens in place of the standard square rubber eyecup
and provides a 90-degree view for framing and composing your image at right angles
to the original viewfinder, useful for low-level (or high-level) shooting. (Or, maybe,
shooting around corners!)
■DK-21M magnifying eyepiece. Provides a 1.17X magnification factor of the entire
viewing area (unlike the 2X DG-2 eyepiece, which enlarges the center of the image),
making it easier to check focus. You might have to move your eye around a little to
see all the indicators outside the image frame, but this magnifier is still suitable for
everyday use.
■SC-28 TTL flash cord. Allows using Nikon speedlights off-camera, while retain-
ing all the automated features.
■SC-29 TTL flash cord.Similar to the SC-28, this unit has its own AF-assist lamp,
which can provide extra illumination for the D7000’s autofocus system in dim light
(which, not coincidentally, is when you’ll probably be using an electronic flash).
