With extended battery, possible shotgun mic, or wireless mic receiver, you're probably looking at right at that possibly a tad over that about somewhere 6-7.5 lbs. I would guess. Believe me, PLEASE!!! DO NOT SELL YOURSELF CHEAP!!! You've got a great camera there, and you want to shoot the best footage possible with it, you've already made a major investment in that camera, now invest in a good mount!! Those Primos mounts are too flimsy for your camera and it doesn't have a fluid head either. Get a good arm with a good brand fluid head, preferably a Bogen/Manfrotto fluid head. For that camera at least the 700RC2 fluid head or possibly look into the 501 fluid head. As far as arms are concerned, get one that is overbuilt not under built or right at weight capacity. There are several good brands out there, we use the Hunter Cam Cradles. Either way the footage will only be as good as the mount you are shooting from, so match your quality camera with a quality arm and head!! Good luck and I look forward to seeing what you shoot with that camera.
