４）Shooting Features
⑴Autofocus
● AF sensor
The EOS D REBEL XTI / EOS 400D D uses the same
9-point AF sensor (Fig. 008) as the EOS 30D. With f/2.8
and larger aperture lenses, the center AF point works as
a high-precision, cross-type sensor. The AF can operate
under ambient lighting ranging from EV -0.5 to EV 18.
This range is one stop wider in low light than the EOS
KISS DIGITAL N's.
＊ The EOS D REBEL XTI / EOS 400D D is Canon's first entry-level
SLR with 9-point AF and cross-type sensor compatible with f/2.8.
●Selectable AF mode
In the Creative Zone modes, the AF mode (One-Shot
AF, AI SERVO AF, or AI Servo AF) is user selectable.
●Selectable AF point
You can select the AF point by pressing the cross
keys (or turning the main dial) while looking at the AF
point selection screen (Fig. 010) or the superimposed
AF points in the viewfinder. You can also toggle
between automatic AF point selection and center AF
point selection by pressing the SET button.
⑵Drive mode
At a continuous shooting speed of approx. 3 fps,
a maximum burst of 27 shots in Large/Fine mode
is possible. The maximum burst in RAW mode is 10
shots (about twice that of the EOS KISS DIGITAL N).
Although the higher number of pixels makes the image
file size larger, continuous shooting still gives ample
performance.
⑶Shutter
The shutter unit has the same basic configuration as the EOS KISS DIGITAL N's. The
shutter speed range is 1/4000 sec. - 30 sec. Bulb and X-sync at 1/200 sec. are also
provided.
⑷Exposure control
The shooting modes, 35-zone metering sensor, and metering modes (evaluative, partial,
center-weighted average metering) are all the same as the EOS KISS DIGITAL N's.
