Visible crew/equipment: There is a scene where Michael Myers is hiding behind a hedge bush and Laurie and her friend go to investigate. Laurie turns around and talks and you see cigarette smoke go by the camera (John Carpenter admitted on the commentary track that he was smoking a little too close to the camera that day). (00:24:10)
Visible crew/equipment: When Roger hits the zombie with the truck, notice at the bottom right a trampoline from which the zombie jumps off. (01:04:55)
Visible crew/equipment: In the scene where Brody approaches the group of teenagers on their smashed boats, the angle cuts to show Brody approaching seen as if from Cable Junction. At this point, there is a huge mistake. The teenagers' boats are clearly visible in the foreground, the kids have all completely vanished, and you can spot the cameraman standing on the boats quite clearly.
Suggested correction: If it's the angle I'm thinking, I think this is wrong. The first boat to appear in that short is of Lucy and Patrick, but the positioning of the fencing joints plus the boat visible is simply the upturned Marge and Sean's boat that Sean was rescued from before this.
Visible crew/equipment: In the scene near the start of the movie when Lois Chiles is showing Mia Farrow her bathroom and Mia Farrow is saying "Yes, It's lovely," on the mirror on the right you can see a member of the crew crawling around on his hands and knees.
