ZEBRA switch

By setting the ZEBRA switch to ON, oblique stripes (zebra pattern) can be displayed in the sections with a luminance level of 70% to 80% or sections with levels over 100% in the viewfinder.

The zebra pattern can be used as a reference for manual iris adjustment.

When adjusting the iris manually, adjust it so that the zebra patterns are displayed in the section that you want to stress in the subject.

When CHARACTER of the Camera SETUP Menu screen is set to ON, the zebra pattern will also appear in the MONITOR OUT connector video.

The zebra pattern will also appear during color bar output when the ZEBRA switch is set to ON.

The initial setting is 70 to 80%. However, using the "ZEBRA" setting on the VF DISPLAY MENU, zebra patterns can be displayed in the sections with a luminance level of 85% to 95%, over 95% and over 100%.

See "VF DISPLAY MENU Screen" on page 78.
