C.Fn II -1 Long exposure noise reduction

0:Off

1:Auto

For 1 sec. or longer exposures, noise reduction is performed automatically if noise typical of long exposures is detected. This [Auto] setting is effective in most cases.

2:On

Noise reduction is performed for all exposures of 1 sec. or longer. The [On] setting may be effective for noise that cannot be detected or reduced with the [Auto] setting.

With setting 1 and 2, after the picture is taken, the noise reduction process may take the same amount of time as the exposure. During the noise reduction, shooting is still possible as long as the maximum burst indicator in the viewfinder shows “1” or higher.

With setting 2, if a long exposure is used during Live View shooting,

“BUSY” will be displayed and the Live View display will not appear until the noise reduction process is completed. (You cannot take another picture.)

C.Fn II -2 High ISO speed noise reduction

Reduces the noise generated in the image. 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. Change the setting to suit the noise level.

0:Standard

1:Low

2:Strong

3:Disable

With setting 2, the maximum burst for continuous shooting will greatly decrease.
