Battery grips attach to the base of the camera and provide
increased battery life by allowing the use of two batteries
at once.
Batteries provide the power for your digital camera.
The batteries for all current EOS models make use
of Lithium Ion technology.
An AC adapter will allow you to power you EOS camera from a
main power supply. If you are involved in studio photography,
using mains power avoids the need to change batteries
during the shoot. This is especially useful when shooting
tethered to a computer.
The Angle Finder C attaches
to the viewfinder of your
EOS camera and allows
you to look down into the
viewfinder.
This is especially useful with
low-level photography where it
may not be possible to put your
eye to the viewfinder.
The addition of a 2.5x magnification
option makes critical manual focusing
easier as you have an enlarged view
of the centre of the frame.
Many EOS models feature
interchangeable focusing
screens. While the standard
screen provided with the
camera is ideal for most
general purpose shooting
there are other screens
available for specialist uses.
When using an EF 85mm f/1.2L II
USM lens for example, you may find
the Precision Matte screens (Ec-S,
Eg-S or Ef-S) provide a better view
and aid in manual focusing.
For architectural photography,
the Precision Matte with Grid screens
(Ec-D, Eg-D and Ef-D) are useful as
they allow you to check verticals.
The EOS–1 Series models feature
a wider range of optional focusing
screens allowing you to tailor the
cameras to your requirements.

An AA battery magazine can also be
fitted to allow powering of the camera
from AA batteries in an emergency.
Battery grips also provide shooting
buttons for taking pictures in portrait
format. This is more comfortable and
stable and when shooting vertically.
Using a battery grip when shooting
with long telephoto lenses will
also make the camera-lens
system balance better.
This provides longer battery life and
does not suffer from a memory effect.
They also hold their charge well when
not used for long periods of time.
Lithium Ion batteries offer one of the
best energy to weight ratios of any
battery technology currently available
meaning the batteries can remain
small and lightweight.
AC adaptors are also recommended
for when you perform a manual
sensor clean, as it will reduce the
risk of the shutter and mirror closing
during cleaning.
For mobile photographers, the
Car Battery Charger allows you to
recharge your battery from a 12 volts
car socket. This removes the need
for mains power and is useful for
photographers working in remote
locations.
