Incredible quality of the camera. GoPro can't compare to the fluidity and high quality of these movies. The expensive price is the only drawback. If you don't get genuine Sony batteries, mounts, and monopods, you may expect to spend an extra $10,000 to $15,000. I'm relieved to have found the best action camera available. has certain advantages: Superior optical and electronic steadying. The photography is also top-notch. Contrast several: Bad equipment, all I have is an aquabox. Original mounts are quite costly. The screen is absent.
