Focusing Screen

You can change the focusing screen to an Ec-series focusing screen more
suited for your shooting. If you change the focusing screen, change this
setting to match the focusing screen type to obtain the correct
exposure.
Std.: Ec-CV
Standard focusing screen.
: Ec-A, B, D, H, I, L
For Laser-matte screens.
Since the Ec-A/B/I/L focusing screens have a prism at the center, the
correct exposure cannot be obtained with evaluative metering or center
spot metering. Use either center-weighted average metering or AF point-
linked spot metering (except the center AF point).
Since the Ec-A/B/I/L focusing screens have a prism in the center, AF
based on the color and facial information of a subject at the center of the
viewfinder may not be achieved, even if [Auto AF pt sel.: EOS iTR AF]
is set to [Enable] (p.95).
Although an Ec-C/CII/CIII/CIV/N/R/S focusing screen can be installed in
the camera, the correct exposure will not be obtained. Use a
commercially-available light meter to set a manual exposure or set
exposure compensation and shoot.
The Area AF frame displayed on the Ec-CIII/CIV/N/S focusing screens is
different from this camera's AF Area.
To change the focusing screen, refer to the instructions that come with the
focusing screen.
