Nikon Corporation is pleased to announce the introduction of Wireless Transmitter WT-4, that enables image transfer and camera control from a computer connected with a camera via USB cable, and remote-control software Camera Control Pro 2. The Nikon WT-4 Wireless Transmitter, when connected with the Nikon D3 or D300 digital SLR, permits image transfer to a computer connected wirelessly or using Ethernet cable, or to an FTP server. Wireless printing is also made possible via computer. Furthermore, the newly added Thumbnail Select mode realizes wireless transfer of images to a computer taken with several cameras connected to the new Nikon WT-4 Wireless Transmitter.

Nikon WT4 Transmitter - Software
Camera Control Pro 2 enables adjustment of various settings of Nikon digital SLRs from a computer, and saves them. In addition to the functions of Camera Control Pro introduced in 2006, Camera Control Pro 2 supports various functions of the Nikon D3 and D300 such as Preview prior to transfer to a computer, Live view and Picture Control System. Thumbnail display function is also available. With these advanced features, Camera Control Pro 2 is essential software for studio shooting, etc.

Nikon WT4 Wireless Transmitter - LAN and Transmission range
When using Camera Control Pro 2 with the Nikon WT-4 set in PC mode, camera operation can be controlled from a connected computer. This is convenient in large-volume studio shooting for confirming images on a computer display. The Nikon WT-4 is a high-performance wireless transmitter that offers diversified image transfer capabilities when connected with the Nikon D3 or D300 via USB cable. It supports wireless LAN conforming to IEEE 802.11b/g, IEEE 802.11a, and wired LAN conforming to IEEE 802.3u (100BASE-TX) and IEEE 802.3 (10BASE-T). Transmission range when wireless LAN is used is approx. 180 m (IEEE 802.11b/g) or 260 m (IEEE 802.11a). (Varies according to transmission conditions.)

Nikon WT4 Set - Cable connection and Wireless support
External dimensions are approx. 125 (W) x 65 (H) x 35 (D) mm, and weight is 131 g (body only). In order to maintain operability of a camera, the WT-4 is not directly mounted on the camera bottom, but is connected via a cable. A soft case that can be attached to a belt and a neck-strap are supplied as standard accessories. With wireless LAN, IEEE 802.11b/g and 11a are supported. With wired LAN, IEEE 802.3u (100BASE-TX) and IEEE 802.3 (10BASE-T) are supported. With wireless LAN, transmission range is approx. 180 m (IEEE 802.11b/g) and 260 m (IEEE 802.11a). Ad-hoc mode enables peer-to-peer connection of a WT-4 and a computer or FTP server. Infrastructure mode enables connection via an access point.

WT4 Wireless Transmitter connection modes
• Image Transfer mode: Images stored in a memory card and those just taken can be transferred and saved on a computer or FTP server
• Thumbnail Select mode: Thumbnail images can be displayed on a connected computer, and selected images can be downloaded and saved
• PC mode: With Camera Control Pro 2 (optional), camera settings can be controlled and images taken can be transferred and saved on a computer
• Printer mode: JPEG images stored in a memory card can be transferred to a printer connected with a computer

Nikon WT-4 Wireless Transmitter - Thumbnail and Multi-connection
When the Nikon D3 or D300 is connected with the WT-4 via USB cable, several cameras can be wirelessly connected with a computer. This mode permits thumbnail display of images taken with up to five wirelessly connected cameras on a computer display. Images selected by confirming the thumbnail can be downloaded and saved on the computer. With this mode, both photographer and computer operator can concentrate on their own assignment
