EF24-105mm f/4L IS USM announcement |
|
|
|
Canon has identified a fault that can occur in some early versions of EF24-105mm f/4L IS USM lenses.
|
|
The fault occurs in the form of shower-like ghosts, or flares. The flare will not appear under normal shooting conditions, so the lenses can be used without trouble in most circumstances. However, under limited conditions (such as backlit or night scene
shots where a strong light source shines from behind the shooting object), a flare may appear. In those instances, users can avoid the effect by slightly changing the camera’s direction or focal length (angle of view) while checking for flares through the
viewfinder.
To determine if your lens is affected, please check the control number of the product. Canon will repair affected products free of charge, and apologises for any inconvenience this may have caused.
Affected model and control numbers:
EF24-105mm f/4.0L IS USM
The control number is indicated on the back cover of the lens (see the example shown in the red ellipse on the right). If it contains the letters UT followed by a number under 1,000, the product may be affected.
Should you have any difficulty identifying the control number, please contact Canon’s Customer Service helpdesk in your country.
Repair services:
Free of charge repair services will start from November 15, 2005. For further inquiries, users who have affected products are asked to contact the helpdesk.
