⑵Drive
Continuous shooting speed at approx. 6.5 fps (maximum) and approx. 3 fps. The drive
mode selection loop now includes 2-sec. self-timer.
The maximum burst during continuous shooting is approx. 75 Large/Fine shots and
approx. 17 RAW shots (both during high-speed continuous shooting). Despite the higher
number of megapixels due to the larger image size, continuous shooting is still fast.
⑶Shutter
(=EOS 30D)
The shutter unit is the same as the EOS 30D's. The shutter speed range is 1/8000 sec.
to 30 sec. with Bulb and X-sync at 1/250 sec.
⑷Exposure control
(=EOS 30D)
The shooting modes, 35-zone metering sensor, and metering modes (evaluative, partial,
spot, and center-weighted average) are all the same as the EOS 30D.
⑸Viewfinder
●Viewfinder optics
To make the viewfinder clearer to see, 0.95x
magnification, 26.4° angle of view, and 22mm
eyepoint are provided. (The EOS 30D's viewfinder
gave 0.9x magnification, 25.1° angle of view, and
20mm eyepoint.)
●Focusing screen
Interchangeable. Besides the standard focusing
screen, there is one to make it easier to see the
point of focus and one with grid lines.
●Viewfinder display
Besides the EOS 30D's viewfinder's display items, the EOS 40D's viewfinder display
now includes the ISO speed (always displayed) and B/W shooting icon. Also, the
maximum burst is now displayed in 2 digits instead of only 1 digit.
⑹Live View shooting mode
Compared to the EOS-1D Mark III's Live View shooting mode, the following
improvements have been incorporated:
● S horter shutter-release time lag and silent
shooting mode
The EOS 40D's CMOS sensor has an electronic
1st-curtain shutter function. It enables shooting
with the mechanical shutter completely open. As
a result, the [Silent shoot.] (Fig. 014) Mode 1 and
Mode 2 make the shutter-release time lag shorter
and reduce the shutter-cocking noise.
With Mode 2, the shutter cocking does not
occur after shutter release. It occurs only when the shutter button is SW-2 OFF. When
the shot is taken, only the shutter curtains make noise so the shooting is quiet.
＊ L ive View shooting with EOS-1D Mark III had the shutter closing after the shutter release before the start of
the exposure. This caused shutter-release time lag and shutter-cocking noise.
