Angenieux Optimo 24-290 on a Dana Dolly

Carefully balancing the Arri Alexa Mini with an Angenieux Optimo 24-290 on the Dana Dolly with an OConnor head. You have to  pay close attention and use extreme caution because if the camera tips forward or back it can roll off the speedrail. The shot came out great and no cameras were harmed. Bonus points for noticing the triple break on the 18K in the background
