Quick. Easy. Convenient.
The launch of the WT-2 gives digital photography an invaluable new dimension.
You said that in terms of performance, the new WT-2 marked a radical improvement over the WT-1. What has changed, specifically?
There are three major changes. First, the package uses PTP/IP (Picture Transfer Protocol over Internet Protocol) developed by FotoNation Inc., and includes "Wireless Connecting Utility" software to support connection settings using PTP/IP, making wireless LAN connection very easy. With the WT-1, FTP (File Transfer Protocol) was only available for image transfer. But for the WT-2, Nikon independently adjusted the PTP/IP for easier image transfer between a camera and PC.
Second, the WT-2 makes image transfer speed dramatically faster by making it compatible with the IEEE802.11g standard. In theory, connection to a wireless network with IEEE802.11g makes transfer speed five times as fast as communication with IEEE802.11b, the standard compatible with the WT-1.
Third, the Remote Camera Control function of "Nikon Capture 4 (version 4.2)" image-editing software lets a user control a camera via wireless remote.
The WT-2 seems to mark an evolution of the Wireless Transmitter. How do you feel about the changes it embodies?
To me, the most impressive change is the easier connection. To tell the truth, the WT-1 had a reputation for being difficult to connect to wireless LAN, especially for those less knowledgeable about networking. So in developing the WT-2, it was important for us to improve in this regard. This time, in addition to using PTP/IP and including "Wireless Connecting Utility," we explain details about how to connect to wireless LAN on websites and instruction manual, using easier-to-understand terms and instructions than we used for the WT-1. So I think that even those with little knowledge of networking technology can use this product, without reservations.
It's also nice to be able to control the Remote Camera Control function of Nikon Capture 4 (version 4.2).
I agree. The Remote Camera Control function offers PC control over various settings and operations, including focus and exposure adjustment, through USB cable connection of a PC installed with "Nikon Capture 4 (version 4.2)" and camera. The WT-2, however, lets you use this function without the USB cable connection, making it useful for shooting birds in their natural habitats, for instance. Just position the camera close to a bird's nest, and control shooting from a distance without worrying about disturbing the birds. Many such applications are possible, according to shooting situation. As with the WT-1, the camera-attachable structure should enhance convenience.
- The WT-2 can be used with "Nikon Capture 4 (version 4.2)" for camera remote control that dramatically expands the capabilities of digital photography.
This gives you better control of shooting operations as well as image data transmission, doesn't it?
Exactly. At the Athens Olympics, a photographer covered a camera and WT-1 with a waterproof case, then submerged the package in the swimming pool. The antenna remained above the surface of the water, as the photographers used the cable to take underwater pictures of swimmers. In this case, since the WT-1 was used, the shutter was released by using a separate cable. But a combination of WT-2 and D2X or D2HS makes it possible to perform wireless shutter release, as well as focus and exposure setting.
