Interface The USB 2.0 Hi-Speed is now incorporated, replacing IEEE 1394/Firewire. Thanks to the higher efficiency of the internal interface with DIGIC III, data transfer speed is much faster than with the EOS-1D Mark II N. Since the USB speed also greatly depends on the personal computer hardware environment, the transfer speed might not be about 2.5 times as fast in all user environments. The USB interface cable is about 6.6 ft./2m long with both ends having a ferrite core-equipped A: Mini B connector. It can be used to connect the camera to a personal computer, printer, external media (via WFT-E2A), or GPS. An optional 16.4 ft./5m cable has also been developed. A cable protector for the EOS-1D Mark III has also been developed to prevent deformation or damage of the terminal due to excessive strain on the terminal, to reduce wear, and to prevent the USB cable from being disconnected accidentally. The cable protector is designed to be usable even while the WFT-E2A is attached to the camera. Cable protector A 15-pin extension system terminal is provided for connection to the Wireless File Transmitter WFT-E2A. Because this terminal is located behind the USB and other connections, the other terminals can still be used even while the WFT-E2A is attached. Terminals other than these are the same as with the EOS-1D Mark II N: PC terminal, video out terminal (NTSC/PAL), and remote control terminal (N3 type). Power The EOS-1D Mark III's power source system has been changed from the old EOS-1D power source system. The new, dedicated, high-performance, lithium-ion Battery Pack LP-E4 (3 cells, 11.1V, 2300 mAh) is compact and lightweight, taking full advantage of current lithium-ion technology. Compared to the NP-E3, it is much smaller Battery Info. (40% less volume) and lighter (46% lighter). It can also communicate the following information with the camera: Power source type, remaining capacity 6-level icon, display in 1% increments, shutter count, and recharge performance (3 levels). This information can be viewed with the [Battery info.] menu. The new system also consists of Battery Charger LC-E4 and AC Adapter Kit ACK-E4. VIII. ROCK SOLID RELIABILITY Battery Pack LP-E4 37

Interface
Power
The USB 2.0 Hi-Speed is now incorporated, replacing IEEE 1394/Firewire. Thanks to the
higher efficiency of the internal interface with DIGIC III, data transfer speed is much
faster than with the EOS-1D Mark II
N
. Since the USB speed also greatly depends on the
personal computer hardware environment, the transfer speed might not be about 2.5
times as fast in all user environments. The USB interface cable is about 6.6 ft./2m long
with both ends having a ferrite core-equipped A: Mini B connector. It can be used to
connect the camera to a personal computer, printer, external media (via WFT-E2A), or
GPS. An optional 16.4 ft./5m cable has also been developed.
A cable protector for the EOS-1D Mark III has also
been developed to prevent deformation or damage
of the terminal due to excessive strain on the
terminal, to reduce wear, and to prevent the USB
cable from being disconnected accidentally. The
cable protector is designed to be usable even while
the WFT-E2A is attached to the camera.
A 15-pin extension system terminal is provided for
connection to the Wireless File Transmitter WFT-E2A.
Because this terminal is located behind the USB and
other connections, the other terminals can still be used
even while the WFT-E2A is attached. Terminals other
than these are the same as with the EOS-1D Mark II
N
:
PC terminal, video out terminal (NTSC/PAL), and
remote control terminal (N3 type).
The EOS-1D Mark III's power source system has been
changed from the old EOS-1D power source system. The
new, dedicated, high-performance, lithium-ion Battery
Pack LP-E4 (3 cells, 11.1V, 2300 mAh) is compact and
