Part 1: General Information
impossible. The time required for refocusing causes the irregular shooting speed. This also
occurs on the EOS 1 OS.
Infrared film cannot be used.
The camera's photo reflector emits infrared
light to detect the film perforation. Infrared
film will therefore be fogged. This also
occurs with the EOS A2/A2E.
As illustrated, about 9 mm of the film from
the top edge will be ruined by the infrared
light. About 15 percent of the rest of the film
area will be fogged to some extent.

focusing point. As shown below, they have the same
diameter and they do not overlap.
