On a different note. While shooting with the 5D a couple of weeks ago, the camera's reflex mirror suddenly came loose. My boss promised me an upgrade budget at the start of the year so I thought it's time to ask for the 5D MIII. I pre-ordered the camera last week. B & H tells me yesterday that I probably won't get the camera until May. In the meantime, Canon costumer service informed me that the reflex mirror becoming unglued is a known problem with older 5Ds. They fixed it for free and got it back within a few days.
