My shooting was much steadier [with the HDV-PRO] vs. straight handheld operation, and after a full week of shooting I experienced little residual back soreness or discomfort. The Panasonic battery adapter [XP-DV-P20 cable] worked very well, and one standard Switronix battery [XP-L130A] powered the HVX200 camera for 10+ hours. I like having the extra power tap near the camera to power additional accessories. Nice bonus feature.-Will Bezubic, Running Pony Productions
