Visible crew/equipment: After the Iguana changes back, the camera pans up from the floor and you can see the camera shadow moving up Billy's leg. (00:18:10)

Visible crew/equipment: Just as the Rangers find a way to defeat Lord Zed's putties, we see a camera shot circulating the rangers. Pay attention and you will see that there is one shadow on the ground that doesn't move. Clearly from a member of the film crew. (00:16:40)
Visible crew/equipment: When the Pink, Green, Black and Red rangers teleport to take on the monster, we see the Pink ranger walk towards the camera. As she does, so the stage lights are reflected in her helmet. (00:13:30)
