To Customers Who Use the EF 70-300 f/4-5.6 IS USM Lens:

Thank you very much for your patronage of our products.

We recently informed you of a phenomenon in which some images captured by the EF 70-300 f/4-5.6 IS USM lens appear in insufficient resolution. This phenomenon may be seen at the edge of the frame at the 300mm setting when the camera is held vertically.

We are very sorry for the inconvenience that this phenomenon represents for customers who use this lens and appreciate your understanding and cooperation.

We have been studying the symptoms of this phenomenon in order to determine its precise cause and to develop an appropriate remedy. We have now determined the cause and have developed the remedy.

This phenomenon affects all EF 70-300 f/4-5.6 IS USM lenses with a "0" or "1" in the third digit of the (8 digit) serial number. Products that have a third digit of "2" or higher in their serial number are not affected.

We will make inspections and repairs free of charge for customers who are experiencing this phenomenon, so please contact our call center. In addition, our call center will start accepting inquiries regarding affected products from July 18, 2006.
