Major Accessories (Optional)
Battery Pack BP-511
This is a powerful lithium ion rechargeable battery pack.
The rated voltage is 7.4V. You can use the Compact Power
Adapter CA-PS400 to charge the BP-511 battery pack,
and when fully charged it has enough power for you to
take approximately 490 images (Normal, with 50% flash
use). Charging takes about 90 minutes.
Battery Grip BG-ED3
This is a battery grip that holds two BP-511 battery packs.
It provides a shutter button, electronic dials, AE lock/FE
lock button, and AF point selection button for use in taking
portrait (vertical) shots. (Can also use the DC coupler)
E-series Dioptric Adjustment Lenses
One of ten E-series dioptric adjustment lenses (-4 to +3
diopters) with eyecup can be attached to the camera’s
eyepiece to further expand the dioptric correction range.
Shoe-mount Speedlites
Flash photography with an EX-series Speedlite is as easy
as normal auto exposure shooting without flash. All EX-
series Speedlites enable E-TTL autoflash, high-speed
sync (FP flash), and FE lock. With the 550EX, an easy-to-
use, wireless E-TTL autoflash system is possible with
multiple Speedlites.
Macro Flash
The EX-series Macro Lites are ideal for macro flash
shooting.
You can fire only one or both flash tubes and control the
flash ratio to easily obtain sophisticated lighting effects
with E-TTL autoflash. Also, high-speed sync (FP flash), FE
lock, and a multi-Speedlite, wireless system (with 550EX
as a slave) are possible to achieve various macro flash
effects.
