Visible crew/equipment: When the astronauts are running down a dusty hill in the desert, you can spot the shadow of the camera on the back of Landon and Dodge. (00:15:50)
Visible crew/equipment: During one of the scenes where an astronaut does an EVA (Extra Vehicular Activity or "Space Walk"), you see him floating slowly from the Pod shuttle towards the Discovery. This was filmed by hanging the pod on the ceiling and lowering the actor from it with a rope towards the camera that's pointing upward. If you look carefully, you can see the shadow of the rope.
Visible crew/equipment: When Barbarella is in her anti-gravity state during the credits, in a closeup of her removing her gloves, you can see reflections of her hands and the gloves in a plexiglass screen under her, which was to give the illusion that she was floating in the air. (00:00:50)
Visible crew/equipment: In the scene where the Germans are pursuing Richard Burton's escaping party as they make their way towards the aircraft waiting for them, you will see the first of two pursuing German Kubelwagons being hit with machine gun fire and flipping. When this happens, you will see a cable used to flip the vehicle on the bottom left side of the screen being quickly retracted as it becomes detached from the Kubelwagon's axle.
Visible crew/equipment: During the long car chase, after Freya tells Matt that he's an awful driver Matt makes a sharp right turn and the car chasing them stops short, and when they back the car up we can see the reflection of a crew member wearing a hat (perhaps the cameraman) on the car window.
