seattlebruin Offline Upload & Sell: On

Hi all - I was shooting an airshow yesterday with the 5DIII/150-600C combo that I regularly use and noticed a weird thing with zone focusing. If I had the zone focus set to the top nine points in the center grid, occasionally the lens would simply stop trying to AF.
The lens functioned fine in every other mode except those top 9. It took a camera restart to get them working again, but it happened periodically throughout the day.
Anyone else seen something like this?
