I have the Cam for 111 -, snatched in Saturn and thought I had made a great bargain. Sorry, but I soon realized that the waterproof case, which is included, holds very muddy images. After a short research I found out, unfortunately, that you take underwater shots one (ie this) other cover need. The optimized cover (for underwater filming) then is also a "normal" acting. At first I thought that it is unnecessary, however, was the also optimized ?! This cover has namely holes's microphone, thus you have a better sound than the "original cover". Why does Sony something ??? Now I have 3 cover and need really only 2 !!! The cover, which has the holes for micro's is not 100% waterproof but he does not need, because for that I've now flat and somewhat clunky cover. Somehow I do not understand ... Well, but as you can seemingly justify the extremely high price ?! That's why only 4 stars! Otherwise the set is ok
