The biggest problem with the Sony surrounds the mounts, not only the lack of choice but also the shape and design of the supplied case. The fact that it completely blocks off the microphone, can't be tilted up or down, can't be mounted to the side of things, but is also too long and tall to be mounted on the top of a helmet means that the Sony ultimately fails as an action cam. I will be experimenting with finding some way to attach the camera to my bike helmet whilst also recording sound through the mic-in socket…. but I'm really more interested in using this as a general purpose mini camera. For example when I was shooting another review over Christmas it turned out to be the most suitable camera I owned for filming inside the cramped interior of the car when I needed to demonstrate how a Car DVR mounted to the windscreen. I'm also looking forward to getting the Camcorder type mount if/when it is released. This apparently adds both an LCD screen and a much needed tripod hole to the camera. I should mention again the low light recording capabilities which are really amazing and the best I've ever experienced in any camera.
