Photographers can use the WR-1 to simultaneously release the shutter on multiple Nikon D-SLR cameras that have a WR-R10 and/or WR-1 units attached and have been paired with it. Likewise, the WR-1 can be used as a transceiver, to be controlled by a WR-T10 that is paired with it. The WR-1 is compatible with the WR-T10 & R10 as long as the WR-1 is set to Group A as the WR-R10/WR-T10 system is fixed on Group A.
The WR-1 has access to 15 radio frequency channels (1-15), to prevent interference when multiple pairings or photographers are shooting in one location. Using the WR-1 display, you can even visualize the traffic in each of the 15 channels and select the one with the least amount of traffic to minimize interference.
The WR-1 can be designated as a "master" and control the shutters of up to 20 WR-1 units, or 64 WR-R10 units. The WR-1 is compatible with the WR-T10 & R10 as long as the WR-1 is set to Group A as the WR-R10/WR-T10 system is fixed on Group A. When using the release delay mode on the WR-1 transceiver, different delays can be used for different receivers, allowing the shutter release to be staggered over a series of cameras using a single transmitter.
When using a WR-1 as a transmitter and another as a transceiver, a third WR-1 unit can be used as a relay unit to effectively double the distance (line of sight) to the same 394 ft between units.
When connected to a D4, D800/D800E, D600, D5200 or D7100 D-SLR, the Fn button on the WR-1 has full control of the features that the camera's Fn button controls.
Up to 20 WR-1 units can be used at one time (including 3 transmitters).
The WR-1 also can access up to four groups (A, B, C, D), to further separate out groups of cameras that need to be controlled independently and simultaneously.
Useful for triggering the shutter remotely when using slower shutter speeds (up to 60 minutes) for long exposure photography, to prevent camera movement as well as when shooting interval timer photography.
Range (line of sight) from a WR-1 to another WR-1 is approx. 394 ft.
When connected to a camera as a transceiver, the WR-1 must be connected to the D-SLR using either an MC-37 or MC-38 cable.
When connected to a D7100 D-SLR, the photographer can view and change camera settings remotely on the camera using the LCD information display on the WR-1.
