9) Film ID Imprinting
The film leader is always imprinted with a user-selec-
table 2-digit number (00 - 99) and a sequential 3-digit
(001 - 999) film ID No. (See Figs. 1-13 and 1-14.) When
multiple EOS-1V cameras are used, the user-selectable
No. can be used to identify which EOS-1V was used to
shoot that particular roll of film. The film ID No. counts
up automatically each time a new roll of film is loaded.
The film ID No. is used as a reference to view or edit the
shooting data of the corresponding roll with EOS Link
Software ES-E1.
The imprinting mechanism is on the standard camera
back. Immediately after the film advances to frame 1, a
transparent LCD numeral is imprinted on the film by a mini lamp. The imprinting
time is 25 ms to 180 ms (depending on the ISO film speed) at 20°C. The power
source is the same as the camera's. The imprinting cannot be turned off. The EOS-
1V camera back cannot be attached to the EOS-1N because the hinge length dif-
fers. It also cannot be attached to the EOS-3 because its inner parts will hit the
EOS-3's film transport detector. Closing the camera back by force will have it pop
up. (The Dateback DB-E2 can be attached to the EOS-1V.)
