I recently added a 2.2 teleconverter to my X12 optical zoom Panasonic PV-GS400. I can do some amazing CUs. But, even locked down, just the wind blowing causes the image to shake! Now, what I'd like to do is capture birds in flight. If I shake on a tripod, hand held is out of the question. Does anyone know how PBS's "Nature" or the Discovery channel videographers capture such amazing footage of birds in flight? Also, how do they handle depth of field. At high magnification, it can be pretty small. Do they shoot with one hand on the focus ring? I'm looking for any insights I can get. Thanks. Dale
