C.Fn-5 High ISO speed noise reduction

Reduces the noise generated in the image. Although the noise reduction is applied at all ISO speeds, it is particularly effective at high ISO speeds. At low ISO speeds, the noise in the darker parts of the image (shadow areas) is further reduced. Change the setting to suit the noise level.

With setting 2, the maximum burst during continuous shooting will greatly decrease. Also, the continuous shooting speed may be slower.

If you play back a 1or 1+73image with the camera or print an image directly, the effect of the high ISO speed noise reduction may look minimal. You can check the noise reduction effect or print noise-reduced images with Digital Photo Professional (EOS software, p.318).

C.Fn-6 Highlight tone priority

0:Disable

1:Enable

Improves the highlight detail. The dynamic range is expanded from the standard 18% gray to bright highlights. The gradation between the grays and highlights becomes smoother.

With setting 1, the Auto Lighting Optimizer (p.119) is automatically set to [Disable] and the setting cannot be changed.

With setting 1, noise (grainy image, banding, etc.) may become slightly more pronounced than with setting 0.

With setting 1, the ISO speed settable range will be ISO 200 - ISO 6400. Also, the <A> icon will be displayed on the LCD monitor and in the viewfinder when highlight tone priority is enabled.
