The Picture Style function has the same specifications as
those of the EOS 30D, but the EOS 40D is also compatible
with Canon's new Picture Style Editor software, which allows
even more control over image quality (see page 26 for
details). The EOS 40D has a separate Picture Style selection
button to the left of the power switch to make selection easier.
Next to the Picture Style button is the INFO. button which accesses the parameter setting
screen. The buttons improve the ease of selecting and adjusting the Picture Style.
CF card access speed is now 1.7 times faster, thanks to
DIGIC III Image Processor, and additional measures have
been taken to keep image data intact while it is being written
to the memory card. With the EOS 30D, if one opens the CF
card slot cover while data is being written to the CF card,
image data would be erased. However, with the EOS 40D
(and the EOS-1D Mark III), data writing continues even if the CF card slot cover is
opened. If the slot cover is opened, the beeper will sound and a warning screen will be
displayed until the cover is closed.
Also, if the power switch is turned off while data is being written to the CF card, a warning
screen is displayed during the writing. When the writing ends, the camera turns off.
During image deletion, images to be discarded are marked with checks. A useful new
function permits the deletion of all checked images simultaneously.
As with the EOS-1D Mark III, image recording can be set to
[Standard], [Auto switch media], [Rec. separately], or [Rec. to
multiple]. The optional settings are used when an additional
USB storage device is connected to the EOS 40D via
Wireless File Transmitter WFT-E3A (see page 32).
Images in the CF card can be backed up to external media
via the WFT-E3A as mentioned above. Besides the quick
backup feature also found in the EOS-1D Mark III, the folder
to back up the images can be created or selected. Only
checkmarked images can be backed up.
Auto ISO
A new feature, Auto ISO speed, is enabled in the Creative
Zone modes. When the ISO is set to [Auto], ISO 400 is set initially. Then, depending
upon the lighting conditions, ISO speed is selected automatically (in 1/3-stop or whole-
stop increments) as shown in the accompanying table. The resulting shutter speed is a
function of the brightness level such with an aim towards reducing blur caused by camera
shake, and also to ensure that the subject does not appear too bright or too dark
because of overexposure or underexposure.
