The
E18 error is an
error message on
Canon digital cameras. The E18 error occurs when anything prevents the
zoom lens from properly extending or retracting.
[1]
The error has become notorious in the Canon user community as it can
completely disable the camera, requiring expensive repairs.
A quick internet search for "E18" + "canon" quickly reveals hundreds of similar complaints.
ConsumerAffairs.com reports that the "lens has a feature called
bellows claw, which is a gear that physically extends and retracts the
lens. A piece that holds the lens, the barrier plate, is not large
enough and can sometimes cause the bellows claw to malfunction,
resulting in a stuck lens". The result is a black screen that only
contains the error message, E18. Another problem mentioned on the site
blames a sticky iris in the lens, caused by grease entering inside from
the microphones built into the lens. The buildup freezes up the ability
of the lens to open.
