I think you all have gotten off the the question at hand.... the author of this thread wants to know where or if someone has a good camera arm for sale, not if or should he use one!!! And definitely this isn't a BIG conspiracy for the sponsors!! Now to answer the original question.... we use the Hunter Cam Cradle tree arms for our videoing with or without a cameraman. I can personally recommend the quality of them to fit the quality of the camera you are using. I've seen a few every now and then for sale on ebay used, but mostly it seems guys are keeping them. You could build your own if you are capable of doing it, or had access to buy the materials needed. I personally wouldn't recommend the cheap little arms you see for sale at the retail stores, they don't have fluid heads and also aren't really capable of handling the weight of the camera you have. They would tend to sag drastically and then you would be un level to pan around. Get good quality equipment, you won't be disappointed with the outcome of your video!! I might also recommend a remote LANC to go along with that setup, it will help to keep your hand movements to a concealed minimum. With this whole setup you will put yourself in great shape to seal the deal and shoot some great footage! Also mentioned before I might talk about, the lens filter.... If you do get one don't skimp, don't buy a $3,500 camera and glass and throw a $25 or $30 cheap piece of glass in front of it and expect it to be as good a quality as the original! I personally don't use a filter, same goes for photography! Use that lens cap to protect the front element when transporting, etc., otherwise get a high quality filter to use to protect the front element. Good luck on your filming this season!
