I have already had sealed boxes (for Panasonic) the one is very good. it has a moisture alarm in the housing Sony goes very well in and everything works properly sealed. I leave one month in the Caribbean and I am well aware many use the bottom. I would complete my review on my return but at first sight and first test locally: perfect. screenprinted tight 60 m and not 40 and plastics have the required thickness for it. allows positioning of screw filters 0.75x67 mmm (or fish eye) bit is set an additional flash on the top, it has a difracteur to the internal flash that can engage from the outside comes with a flexible lens cap all controls are well positioned, colored trigger we just use the lens ring comes with shoulder strap and rubber strap dragone it's the cheapest of the net at the moment (I saw on other sites 250) And especially the only one available and not more expensive than even the Camera!
