Lamar Odom went absolutely nuts on 2 paparazzi in Hollywood this afternoon ... smashing a car, a camera ... and then fleeing the scene -- apparently with some of the destroyed camera gear.
The violent incident was captured on video ... where Mr. Khloe Kardashian was seen going into the back of a car belonging to one of the paps, and chucking all of the guy's equipment into the middle of a busy street.
He then walked across the street and smashed another photog's car with a metal bar, then picked up all the gear from the street and put it in his trunk.
Curiously, right after raging against the paps, Lamar also had a run-in with a fan -- and couldn't have been nicer. Watch the video ... it's kinda bizarre.
