Visible crew/equipment: Just before we see Bruce's sister commit suicide, there is a shot of all Ohara's goons running towards the shack where she is trapped, and in this shot the shadow of the camera is cast on all the men who run by it.
Visible crew/equipment: The head of a crewmember is visible during the mirror room fight. During the part where Lee is slowly moving across a mirror (just before he turns down the corridor and Han comes up behind and slashes his back), look down the corridor where Bruce is about to turn down and you should see it. Also after Han slashes his back Lee turns around and goes back down the corridor and you can see this crewmember again but more.
Visible crew/equipment: During the banquet the camera pans around the room to various scenes, one of which is Roper having a drink and next to him is a circular steel ornament that reflects all the stagelights that are pointing at the action.
Visible crew/equipment: At the first tournament fight, a woman holds a bowl of fruit up to Han and reflected in the underside of the bowl are the feet of the camera operator.
Visible crew/equipment: Near the end of the movie, Bruce Lee knocks Han to the ground and then the shot changes to show a frontal view of Bruce. He then lands a kick to Han's head that sends Han flying across the room. As Bruce moves towards the camera you can see a pointy object on the left side of the screen that a crew member must be holding, because in the next shot there is no pointy black thing in Bruce Lee's path.

Answer: Yes, he filmed all of his scenes before he died. He died on July 20, 1973 - only six days before the film debuted in Hong Kong, and only a month before the film's US debut.
