The focus problem is a tragic flaw worthy of Sophocles. We used the Mark III with a 24-70mm and a 70-200mm zoom. Those lenses should not challenge the 45-spot autofocus system, but the problem was bad enough to show up with it. After the firmware fix, we couldn’t reproduce the problem, but that’s really not good enough. It doesn’t prove the problem is fixed for more challenging conditions. Canon is in the difficult position of proving a negative: that the focus problem no longer exists.
