Canon EOS 5D Mark III Blinking Red AF Point Information

Firmware Coming?
There has been a lot of questions wondering when Canon will release a firmware update similar to the EOS-1D X  that adds the blinking red AF point when in AI servo mode. While I figured they were working on it, I wasn’t quite sure why it hadn’t been brought to market or included with the announced and upcoming firmware update.

This is a direct quote of what I have been told:

They are testing that at the moment but don’t know if it is possible to implement. The former system had a different type of focusing screen and it was easy to handle because it had no reflection in the viewfinder. The new system, with the LCD screen inside the viewfinder is reflecting the red light back and this can affect the light metering system. In the EOS-1D X, the viewfinder box is bigger than in EOS 5D Mark III, which aids in making it possible and workable. In the EOS-1D X they alternate red illumination and metering, and this is why there is the red blinking. With the EOS 5D Mark III, they are testing it but they are not sure if they can make it operate in the same way.

This sounds logical enough, and it’s good to know they are trying to implement it.
