Part 1: General Information
28. Although infrared film can be used with the
camera, slight fogging will occur along the
edges outside the picture area.
29. Be aware that the Ec-N (standard on the
EOS-3) focusing screen looks the same as
the EOS-1V's standard focusing screen
even though the former is a New Laser
Matte screen and the latter is a Laser
Matte screen. Be sure not to set the wrong
CF-0 setting.
30. If a roll of film already partially exposed
with the EOS-1V is rewound in midroll and
then reloaded in the EOS-1V again, a new
film ID will be imprinted over the old one.
31. When CF-13 and CF-17 have been set and
focus is achieved with a focusing point
other than the one selected, spot metering
might not cover the subject whose magnifi-
cation is low. The same applies to center
spot metering and CF-17.
32. Do not attached the EOS-1V's camera
back to the EOS-3.
33. C.Fn-0 cannot be registered in a Custom
Function group.
As per the design.
The EOS-1V's standard focusing screen can be dis-
tinguished by the C III mark on the protruding tab.
The camera cannot distinguish between a new roll of
film and a partially exposed one.

The camera back's inner part will hit against the EOS-
3's film transport detector and the camera will be
unable to close completely. The camera back also can-
not be attached to the EOS-1 and EOS-1N due to the
different hinge length.
The EOS-1V's C.Fn-0 is set to C.Fn-0-1 as the
default setting to suit the standard Lasermatte focus-
ing screen that comes with the camera. However,
when the Custom Functions are reverted to the
default settings with the EOS Link Software ES-E1,
they will all be C.Fn-*-0. So if the user forgets to set
C.Fn-0-0 back to C.Fn-0-1, exposure error will occur.
This is prevented by excluding C.Fn-0 from any
Custom Function group.
