The most obvious external difference between the EOS 20D and the EOS 30D is the new
2.5-inch, 230,00-pixel TFT liquid-crystal monitor with its 170° wide viewing angle and
six LED backlight modules. This is the same monitor used on the EOS-1D Mark II N and
the EOS 5D, both released in the autumn of 2005. Compared with the unit on the
EOS 20D, the new monitor has a viewing
angle 1.94 times larger in all directions, is
much easier to see in daylight, and has a
f
ont size about twice as large and 10%
wider. The monitor has approximately 100%
coverage for JPEG images and 5 levels of
brightness adjustment with a gray chart
displayed along with the image.
Some changes have been made to move the EOS 30D in the direction of the EOS 5D.
The new, large monitor is unmistakable. (It accounts for a 20g increase in camera
weight.) Shapes around the flash head and lens mount have been changed subtly to
suggest Canon’s upper-range models. The mode dial now has a metallic finish. The
grip below the shutter button has been extended for better purchase with the middle
fingers and improved overall handling. A new groove where the middle finger falls
improves comfort and security. The body is 2mm thicker than the EOS 20D’s, also
enhancing comfort and security. Indented surrounds have been added to the row of
four buttons on the back of the camera and the Delete key has been given its own
loc
ation. Lik
e the E
O
S 20D, the 30D is compact, solid, elegant, durable and purposeful.
It is easy to carry and a delight to hold and use. The real design and construction story,
though, is the extent to which numerous internal changes have made the EOS 30D a
meaningf
ul upgrade over the EOS 20D.
Like the EOS 20D, the EOS 30D’s top, front and rear covers are made of a very light
and strong magnesium alloy. Also, the left cover, where the USB port, video port and
other external interface terminals are located, is made of special engineering plastic
which also serves as an electromagnetic shield.
The main body i

high-s

on the mirror box so that the flange focal distance does not change due to static pressure

ed lens. The mirror box is fixed solidly on the chassis to attain a

The external paint is the same high-quality black satin leathery finish found on the EOS
