light leakage reported for 5D MkIII

Apr 6, 2012

http://www.slrclub.com/bbs/vx2.php?id=newproduct&page=1&divpage=7&ss=on&select_arrange=headnum&desc=asc&no=37367

About 10 users have confirmed the same problem.
Basically, outside light is reaching the sensor through the top LCD panel area.
The original poster recommends the following test:

Remove lens and place the body cap.
Put on the eye-piece cover.
This should theoretically block any light from entering the camera.
Set ISO to 800 and set shutter mode to Av.
You should see a shutter speed of around 10 sec.

Now either shine a flashlight near the top LCD panel area or simply turn on the backlighting of the top LCD panel.

This will cause the shutter speed to fluctulate between 5-8 seconds, indicating light leakage.
