Service Notice: Drop-in Circular Polarizing Filters PL-C52 (WII) & PL-C52

Update

Thank you for using Canon products.

We have become aware that some of the above products sold from April 2014 onwards have been assembled with the polarizing filter glass reversely fitted. The details of the phenomenon and Canon’s service policy are described below.

We would like to offer our sincere apologies to users who have been inconvenienced by this issue. Going forward, we will spare no effort in our quality management to make sure our customers can use our products with confidence.


Phenomenon

If an affected filter is used in the orientation as described in the instruction manual, it will not function correctly as a circular polarizing filter.


Affected Products

  1. If the filter has one of the marks shown in the image below, it is NOT affected.




  2. If the filter does not have one of the marks described in 1. above, the method below can be used to check whether or not it is affected.
    i. With the [▲FRONT] marking on the filter facing forwards (towards the computer monitor’s screen).
    ii. Turn the dial to rotate the filter.
    a. Filter does not turn dark (color may change slightly) (image a) filter is affected.
    b. Filter turns dark (almost black) (image b) filter is not affected.


When one of the affected units shown in image a) above is held in the opposite orientation and then rotated, it will turn dark (black). *If an affected unit is inserted in the lens in this orientation (the reverse orientation to that described in the instruction manual), the left and right positions of the rotating dial and lock buttons will be inversed, it will function correctly as a circular polarizing filter.
