我算是後知後覺，今天去逛原廠網站才發現早在30/07/2007就已公布了，官方說法如下：
1.An Image authentication item has been added to the setup menu. The optional Image Authentication Software is required to authenticate images.
2.A Wireless transmitter item has been added to the setup menu. This item is available only when the optional Wireless Transmitter WT-3 is connected to the camera.
看起來好像沒有很必要，不知版上有無大大有心得分享？
