Nikon today announced a new image data transfer protocol named PTP/IP (Picture Transfer Protocol over Internet Protocol). This new protocol is designed to work in a very similar way to PTP (that is the operating system will recognize a connected imaging device and offer transfer features) but that it works over the IP protocol. Nikon's press release hints that this would be useful for transferring images over a wireless LAN, their current WT-1 only supports FTP protocol which can be a little complicated to set up. This development was made in collaboration with FotoNation and Microsoft. The press release also tells us that Nikon are to announce a new wireless transmistter for professional D-SLR's which will support PTP/IP.
