Digital Photography Review exhaustively explains the Nikon D2H's Wi-Fi support: The site's reviewers walk through the hardware and software configuration and then discuss real-world performance from a mid-February photo trade show. The Wi-Fi module has remarkably good characteristics, they report: they were able to take 240 images each day and send 200 of them with two charged batteries (they swapped the battery once per day). It managed a 2.2 Mbps sustained transfer on an open (non-WEP) network.
The configuration could be tedious through a camera back, but the Nikon ships with a Windows-only configuration tool that lets you created a settings file and load it on a Compact Flash card.
The photos of the interface seem to show no WPA support and no secure FTP support, both of which could be useful. If you're transmitting images over a public network, you want to be able to have secure FTP (FTP instead of SSH or other variants) available as an option. Since open networks outside of trade shows typically offer only 512 Kbps to 1.5 Mbps of upstream bandwidth, adding encryption shouldn't cramp one's ability to transmit photos. [via Conrad Chavez]
