買得防水手機，當然有考慮過好大機會會在水中使用，尤是拍攝水中相片機會最大。而現時具有防水能力的手機其實不多，Sony是其中一個品牌有推出防水手機的，不過，最近Sony就發表聲明，指出Sony手機雖然防水，但並建議在水中使用及拍照，是不是表示買一部手機回來，在水中影相還要加多個防水套先好用？
現時Sony旗下的Xperia手機，有部分會加入防水功能，防水能力達到IP68，即是在1.5米的水深之下能使用30分鐘，不過，Sony最近發表的聲明如下：
“Sony devices that are tested for their waterproof abilities are placed gently inside a container filled with tap water and lowered to a depth of 1.5 metres. After 30 minutes in the container, the device is gently taken out and its functions and features are tested.” [Emphasis ours]
“Moving or operating the device while it is submerged is not tested during the laboratory tests. There are also many environmental factors which we could not assess (e.g. water movement or water pressure changes during the movement), if a device is used underwater. Therefore we recommend not submerge our Xperia Z5 in water.”
大意就是防水測試只是在實驗室進行，戶外環境多變，最好不要在水中使用。其實講到底，這種防水級數都只不過用於保護手機，以免生活使用時入水，就算部機不小心跌到浴缸，都不致於報銷，如果你真的拿去水中拍攝，只能說句認真你就輸了。
