Depending on shooting conditions, noise may be intensified with the
effects of correction. Also, stronger application of outline emphasis may
result. In such a case, adjust the Picture Style’s Sharpness as necessary.
The higher the ISO speed, the lower the correction amount will be.
If the image-recording quality is set to
41
or
61
and you set [ Digital
Lens Optimizer ] to [ Enable ], the image-recording quality will be
1
.
If [ Digital Lens Optimizer ] is set to [ Enable ], the continuous shooting speed
will greatly decrease. Also,
41
and
61
cannot be set for the image-
recording quality. If a correction is made during Live View shooting, [ BUSY ]
will be displayed and the Live View image will not be displayed until the
correction process is completed. (Another Live View shooting is not possible.)
If [ Digital Lens Optimizer ] is set to [ Enable ], and you set [ Dual Pixel
RAW ] to [ Enable ], [ Digital Lens Optimizer ] will not function. (The
setting will be switched to [ Disable ].)
During movie shooting, [ Digital Lens Optimizer ] will not be displayed
(correction is not possible).
If [ Digital Lens Optimizer ] is set to [ Enable ], Multi Shot Noise
Reduction cannot be set. Also, even if you assign a button to switch the
image-recording quality to
41
or
61
with [ One-touch image
quality setting ] or [ One-touch image quality (hold) ] in Custom
Controls, that Custom Control function will not take effect.
