Unusual problems with a fine camera

Canon 5D Mark III Shipments delayed While Issue is Investigated

The Canon 5D Mark III is an superb camera with impressive specs and abilities, but according to reports from across the internet, there is one case where it it isn't superb. Specifically when used in dark environments or under bright conditions, light can leak into the camera, causing a 1/3 stop exposure difference. This can be due to the sunlight coming in or even the light from the LCD - a detriment when shooting in a dark studio.

The engineers at Canon are aware of the issue and they've told their retailers that shipments of the Mark III will be on stopped until the issue has been fully investigated.
That is really too bad. But such things do happen occasionally when new products are released. awe are sure that Canon will solve this problem real soon.
