●High ISO speed noise reduction (C.Fn II-2)
This is noise reduction for images taken at a
high ISO speed as in the EOS-1D Mark III. Although
noise reduction is applied at all ISO speeds, it
is particularly effective at high ISO speeds. At
low ISO speeds, the noise in the shadow areas
is further reduced. Also, when [High ISO speed
noise reduction] is set, the maximum burst during
continuous shooting will decrease to 8, regardless of
the image-recording quality.
⑶Highlight tone priority (C.Fn II-3)
This function seeks to improve the highlight detail.
The range is extended between 18% gray and the
maximum highlight tone. This makes the gradation
finer from the grays to the highlights and reduces
blown highlights.
This function also limits the settable ISO speed range
to 200-1600.
⑷White balance
The white balance settings are the same as the EOS
30D's. Only the color temperature (
is new (Fig. 008). The minimum color temperature has
been lowered from 2800K to 2500K in order to cover
tungsten light.
You can now register the personal white balance (1
setting) under < > with the provided software.
The WB correction and WB bracketing settings can
now all be canceled with the INFO. button.
⑸Automatic brightness and contrast correction
In Basic Zone modes, the image is now adjusted automatically during processing to
obtain the best brightness and contrast, due to the shooting results (brightness and
contrast).
⑹Compatible with external recording media
With the WFT-E3 attached to the camera and external recording media such as a
portable hard drive attached via USB, the external media can be selected as the recording
media.
●Image recording function
As with the EOS-1D Mark III, the image recording
can be set to [Standard], [Auto switch media], [Rec.
separately], or [Rec. to multiple] (Fig. 009).
