Nikon US has announced a radio-frequency camera triggering system compatible with all its current DSLRs. The WR-10 system works over a 60m range and, unlike the current infrared system, does not require a line-of-sight between the trigger and the camera. Users of mass-market Nikons (D600 and below) can use the WR-T10 transmitter to focus or fire cameras with WR-R10 receivers attached to them. Owners of pro-grade DSLRs with 10-pin connectors can use the WR-A10 adapter to connect the R10 to their camera. This combination allows the camera to act as a host that can remotely trigger up to 64 other cameras.
