So my crew and I have been extremely bored on a long term shoot. As boys tend to do when we get bored, we goof off a lot.
Moments after this photo was taken the 5D + 35L rig in the pic went tumbling to the concrete. The 5D seems to be OK but the 35L is now a tilt shift lens. I plan to send to Canon CPS to see what they say. The glass seems to be fine. It's just the mount and body that seems to be broken.
Oh well, lesson learned.
