In fact I m not used for a long time but al air very powerful, it replaces a bridge without problem I served me until today. It is very light, perfect for hiking, the zoom is powerful and the photo quality is very good. The goal is bright enough. Unlike devices that I've had before, the screen is much more readable by strong external light. That said, I did have not seen at work in the snow in the sun ... In all a very good device.
