I believe a camera arm is a nessacity for steady footage from the tree.........but your footage is only going to be as good as the arms joints and head.......that said you need to match the weight of your camera to the correct arm ,much the same way you match it to the size of fluid head and tripod........I use the Hunter Cam cradle HD and shoot a Panasonic DVX100 which is comparable in size and weight to your camera.......some don't like that particular arm, but for the money I feel it is a good compromise between a cheap noisy arm and the most expensive (out of my budget) arm. I would suggest you find a buddy or someone that will let you play around with a couple different model arms and choose the one that works best for you.........most times you will know within a matter of minutes whether one particular arm is going to fit your style of hunting and videography.
