Hello… f5.6 to f16 is THREE STOPS! How do you get 1/3 of stop??

When I tested my 5d Mark III it went from f/5.6 to f/16. Hardly a 1/3 of a stop!

Look in the manual, and think about why there is a viewfinder-cover on the neck-strap.

The manual clearly states, that you have to cover the viewfinder when you don’t have your eye at the viewfinder, on a tripod for example.

When you measure the “light-leak” in the first movie, you are WAY under the specified 0EV that the specifications guarantee for the light-meter to work at. Your aperture read 0,0 in your viewfinder – not a normal lens you use. Did it ruin any other pictures than those of the inside of your body-cap?

I’m still in the market for a brand new 5D III – not worried at all by this “defect” !! And i will not send it in for service before other things eventually should happen.

Peter, the viewfinder light leakage is not uncommon on Canon cameras. The literature for my Rebel T2i talks about using the viewfinder cap that is attached to the strap to avoid such leakage when the camera is on a tripod.
