Canon 5D Mark III Error Message 70 Followup

Greetings!  In an earlier post here, I wrote about a brand new Canon 5D Mark III body shutting down with an Error 70 message.  My home town camera store replaced the body because it was DOA. I then purchased a second 5D Mark III body plus the 70-200 f2.8 L Series II lens, as well as all new CF and SD cards that are dedicated to these cameras.  I chose to use the Sandisk Extreme 16GB, and those seem to work well with all of my bodies.  I have a separate set of cards for my two Canon 7D bodies and this system seems to work well.  So far, the cameras have performed beautifully.  One of the new features of the Mark III that I like the most is the silent shutter mode.  It really makes a difference when shooting in many situations.  It seems that if people are less aware of the noise of the camera, they are much more natural and relaxed.  I also like the HDR option on these bodies for when I’m shooting architecture that would otherwise require merging to HDR in Photoshop or Lightroom.  I haven’t taken the 5D Mark III cameras into any seriously extreme conditions yes, but when I head to Svalbard in June with National Geographic Expeditions, we’ll see how they hold up to the arctic.  Right now I use my 7D cameras for wildlife and underwater, which is really great.  I enjoy being able to have 8 fps when photographing subjects like sea lions or surfing.  The 5D Mark III cameras perform well for most editorial and commercial purposes.
