LCD Monitor
Design and Construction
[
Built-in flash func. setting] is a group with [Flash exp. comp], [Shutter sync], and [E-TTL II]
(
Evaluative/Averaged metering). The latter 2 were previously Custom Functions.
[
External flash func. setting] now includes [Wireless set.] from the EOS-1D Mark III's
[
Flash function settings]. This is to enable wireless, multi-Speedlite control. Also, C.Fn
i
tems related to the internal flash, such as flash activation, E-TTL II metering method and
f
lash synch
t
iming, have
been collected
in the flash
setting menu.
The EOS 40D has a 3.0-in. TFT liquid-crystal color LCD monitor with approximately
230,000 pixels and a wide, 140º viewing angle, both horizontally and vertically. Note
that the viewing angle has actually been reduced from 170º on the EOS 30D to improve
ease of viewing outdoors, and that the screen’s brightness level has been increased for
the same reason. Also, the color gamut has
been broadened. Brightness is adjustable to
any of seven levels. The larger monitor size
means a larger font size can be used for
menu display. In all, the LCD monitor is easier
to use and more accurate than before.
Like the EOS 30D, the main exterior covers (top, front, and rear) are made of magnesium
alloy for light-weight and high strength. The grip portion is integrated with the front
cover, enhancing body rigidity further. The body's basic construction is the same as that
of the EOS 30D, employing a stainless steel chassis and a mirror box made of high-
strength engineering plastic. As with the EOS 30D, the exterior has a high-quality, black
satin finish with a non-slip texture. The EOS 40D also
has sealing material lining the CF card slot cover and
battery compartment cover (which is not found in the
30D) to improve dust- and water-resistance. The EOS
40D has sealing material lining the CF card slot cover
and b
attery compartment cover to improve dust- and
water-resistance. The battery compartment covers of
both the Battery Grip BG-E2N and the Wireless File
Transmitter WFT-E3A have sealing material to improve
resistance to dust and water.
The configuration of the major components is basically the same as in the EOS 30D,
with the exception of the following units which have been added or changed:
• Self Cleaning Sensor Unit
• LCD monitor made bigger from 2.5 in. to 3.0 in.
• Two driving motors to attain approximately 6.5 fps continuous shooting speed
• Extension system terminal
