RE: Filming turkey hunts
I pretty much do the same thing with bulk fabric as lungbustersays. I drape it over the camera and let my shotgun mic stick out of the fabric while at the same time covering the legs up. I leave the left side of it so I can see my LCD and work my manual controls as needed. I prefer to shoot through the viewfinder when possible but sometimes if a bird back doors you or makes a big move that's not possible. With this camo "blanket" draped over the camera and me at times I find I can get away with more movement than just a camo camera alone.
I also use a "throw mic" when turkey hunting a lot. Hook a good shotgun mic up to a 25' XLR cable and toss it out in front of you. You'll get that much closer to the bird when it rattles the leaves and the camera noises will not be on your audio track.
