Camera Direct Printing

Two useful additions have been made to printing direct Printing Effects
from the camera. First, a preview display shows effects
such as B/W, Vivid, Brightness correction, Hue, and
Adjust levels before printing. The feature is not enabled
for face brightener or red-eye correction.
Then, tilt angle correction adjusts the angle of images
shot with a tilt to print horizontally. With the trimming
Tilt Correction
screen, turn the Quick Control Dial to tilt the image up to
±10 degrees in 0.5° increments.
As with the EOS-1D Mark III, RAW, sRAW and JPEG printing
and Red-Eye 1 are provided. Camera Direct Printing is
now compatible only with PictBridge. Bubble Jet Direct
and CP Direct are not supported.
Print order (DPOF) and direct image transfer are the same as with EOS 30D.

Interface

USB 2.0 Hi-Speed is provided for the inter-
Extension System Terminal
Terminals
face with personal computers and camera
direct printing. Additionally, the camera
bottom has an extension system terminal,
principally for the Wireless File Transmitter
WFT-E3A. The other terminals, including PC
socket for non-dedicated external flash units, as well as video out and N3-type remote
control, are the same as those on the EOS 30D.
Power: Sources and The power source system is the same as the EOS 30D's and
Battery Compartment Cover
Management uses the Battery Pack BP-511A. With a fully-charged battery,
the number of possible shots without flash use is about
1100 at 73°F/23°C. With 50% flash use, it is about 800
shots. As with the EOS 30D, the date/time backup battery is
the lithium battery CR2016 installed in the battery compartment.
Detaching and attaching the battery compartment cover is now
easier. One pulls it out or puts it back at a 45º angle.
With the Battery Grip BG-E2N, 2 battery packs or 6 AA-size batteries can be used.
To minimize the higher power consumption required by 4-channel, high-speed signal
reading, the output amp's power usage has been kept to an absolute minimum. Also, as
in the case of the EOS Digital Rebel XTi, to save energy during long exposures, power to
the output amp is turned off and the standard current driving the circuit is also cut off.
During Live View Function, power distribution for the signal-reading operation is optimized,
as with the EOS-1D Mark III. Such measures enable more precise power-saving control.
