Matt correct, but which one do you want your expensive camera on when someone in the talent pool or crew accidentally gives it a little bump ? Let's say you are in the middle of a scene and you need to talk to the talent, you walk over to the talent and that actor not in the scene walks by the $20 tripod or is horsing around and gives it a little bump. Which one is easier to get smooth pans ? $20 or $200 ??? The $20 ones tend to fall apart and are too light IMO. Put the cam on it and you have a top heavy time bomb just waiting to crash to the ground. heck even on a windy day, Ive had a tripod want to fall over.
If you have a $200 cam go w/ $20 tripod.. $1,000 cam & lenses, I want insurance.
