C.Fn IV -5     Focusing Screen
If you change the focusing screen, change this setting to match the 
focusing screen type. This is to obtain the correct exposures.
0: Ef-A
1: Ef-D
2: Ef-S
About focusing screen characteristics
Ef-A: Standard Precision Matte Standard focusing screen that comes with the camera. Provides 
good viewfinder brightness and enables easy manual focusing.
Ef-D: Precision Matte with grid This is the Ef-A with a grid. It makes it easier to align horizontal or 
vertical lines.
Ef-S: Super Precision Matte Focusing screen which makes manual focusing easier than with 
the Ef-A. Effective for users who mainly focus manually.
About Super Precision Matte Ef-S and Maximum Lens Aperture
 This is optimized for f/2 .8 and faster lenses.
  If the lens is slower than f/2.8, the viewfinder will look darker than with  
Ef-A.
 Even if all the Custom Functions are cleared, this setting will be retained.
  Since the standard Ef-A focusing screen comes with the EOS 50D, C.Fn 
IV -5-0 is already set.
  To change the focusing screen, refer to the instructions that come with 
the focusing screen.
  The C.Fn IV -5 setting is not included in the registered camera user 
settings (p.186).
