Canon updates 5D Mark III firmware

Canon has released an updated firmware for the 5D Mark III that adds support for the forthcoming 40mm f/2.8 lens and fixes a variety of small power and auto-exposure issues. What was absent was the long-promised support for continuously autofocusing video, which the company confirmed to The Verge has now been ditched from the camera's spec sheet. It looks like if you were hoping to helm your own tense medical drama with one of these, you'd better start looking for the receipt.
