To supplement "my big camera equipment" not always easy to take and above that requires minimal preparation, to capture unexpected photo, I used to use my smart phone. But recently twice, my phone battery "dropped me" when I wanted to take some interesting snapshots. This lack of reliability prompted me to buy this NIKON COOLPIX S9700, that satisfies me completely. For a competitive price, this little device is easy to carry in a pocket. He is always available to catch the moment, since the battery charge is monitored. It has beautiful photographic qualities and an incredible zoom. Of course, on ergonomics and maintenance of the device, one can not make a comparison with the use of an SLR or bridge. There are so many features in such a small area (the opening of the flash is rather surprising when one does not know, but very effective). When shooting, be careful where you put your fingers for good performance, without hindering the development. You may say that for the Smartphone, it is not always easy either. Using this device for spontaneous taken, I work in automatic mode (Flash) that meets my need in most cases. Not waiting for more of this type of device, which completely fills its contract by making me beautiful pictures on the fly, I'm satisfied with my purchase. I must also say that it has options (eg WIFI - GPS) that I do not really use (past the moment of the beginning curiosity). I stay in a basic use.
