2-8
maximum burst increases. Normally, "8" is displayed for the maximum burst.
(4) Shots remaining
When the CF card has room for less than 8 shots taken in the current image
quality mode, the shots remaining will be displayed automatically in place of the
maximum burst. The shots remaining decreases from [8] to [0] with each shot
taken. When the CF card becomes full, "FULL CF" is displayed.
1.5 Exposure control mechanism
1) Metering
The metering optics, 35-zone AE sensor, and metering modes (evaluative, partial,
center weighted average) are the same as the EOS D30's. The metering algorithm
is based on the EOS D30's, but since there were a few user complaints about the
exposure shifting when the picture was slightly recomposed, the metering
algorithm's
α
compensation increment has been made finer, from 1/2 to 1/4, to
obtain more stable exposure control.
2) Exposure control
It is the same as with the EOS D30.
1.6 Drive
1) Continuous shooting speed
It is the same as with the EOS D30.
2) Maximum burst during continuous shooting
With the EOS D30, the maximum burst for Large/Fine is about 8 as shown in
Table 11. In the other image quality settings, the
maximum burst varies. However, with the EOS
D60, the maximum burst is always 8 regardless of
the image quality and ISO speed.
* Despite the EOS D60's higher number of pixels
(more data per shot), the maximum continuous
shooting speed of 3 fps is maintained and the
maximum burst during continuous shooting is
also maintained at the same level as the EOS
D30's. To achieve this, the buffer memory was
increased and the image processing that the
EOS D30 executed during continuous shooting
was eliminated (as shown by Fig. 2-10's red
arrows, the image is processed in accordance
with the stipulated image quality and
parameters from the 1st to 2nd buffers). As a
result, the maximum burst is always 8, limited
only by the 1st buffer memory's capacity.
* During RAW shooting with the EOS D30, the
maximum burst during continuous shooting
was 3 shots due to the 2nd buffer's capacity
