Delivering the convenience of IEEE 802.11g capability, this optional WT-3 enables cable-free image transfer to a computer, with the added safety and versatility of wide-ranging network and security protocols. The WT-3 provides not only wireless functionality but also extended shooting in vertical format. Nikon Capture NX can also be used to control most camera settings and trigger release of the D200 shutter remotely via the WT-3?s wireless capabilities. Images can even be downloaded direct to a computer during shooting, adding further workflow speed and convenience.
