Hello, I am thinking of buying this camera for a beach holiday with the children, considering that with other cameras it will probably be difficult to teach the children to hold the camera properly etc. (in addition to the many other advantages of the camera), now my question, is it suitable for the sea in terms of sand (with premium lenses), sea water (with diving lenses) etc.? I haven't read anything about the robustness and susceptibility to scratches...? Can anyone help me with this? :)
