I already had an earlier model, the tx5 I was very happy but had ended up taking water (or mud rather) after several years of good and loyal service. This waterproof camera has a big advantage over its competitors: it is beautiful! It would effectively re-look and other equipment design sony unsealed, very compact (fits in your pocket). The pictures are always very good. There are the main modes of other sony (freehand pan). The 5x zoom is comfortable compared to predecessors, it is far indeed of current compact with big zoom but it is a sealed unit with the zoom is fully integrated within the device (it does not deploy).
Among the complaints: the transition to the microSD card: a little slower and less convenient because need for an adapter. The protective cover is plastic while in metal. True, this avoids the problems of scratches and paint flaking, it lightens the device, but to the touch it feels a little cheap. After, it remains a detail.
Autonomy is just okay, predict a second battery to be quiet and a carrying case (sony made expressly with a carabiner is perfect ballad to hang trousers or a bag).
