PIXEL KING Wireless Flash Trigger for Canon E-TTL II

This SET include 1 Transmitter and 2 Receivers

Extra receivers if you need:


The King is a second generation system, with the TTL-control based upon the Knight first released in 2009. Like the Pixel Knight, it does not support the Canon wireless protocol(eg:it can not work as ST-E2 to trigger 430EX flash in remote mode), but works by making the remote flash “think” it is in the camera's hot-shoe.

The body is similar to the Pixel Bishop. It uses the 2.4 GHz frequency (unregulated worldwide), and Pixel indicates that has a reach of around 100 meters.

The King provides 7 selectable channels and 3 different groups. For power, both the TX and RX use two AA-sized batteries. Both the TX and RX have an USB-socket to allow firmware updates. Both the TX and RX have a hot-shoe. The RX hot-shoe is for mounting remote Speedlites. However, the TX hot-shoe is not a TTL pass-through shoe, and can not be used to mount an additional Speedlite. Instead Pixel has hinted that they may later introduce a separate control unit (dubbed “N-ETTL”) that can be mounted in the TX hot-shoe and used like the PocketWizard AC3 Zone Controller.

Here is a rundown of its main features:

May trigger both Canon Speedlites and generic studio strobes.
Compatible with Canon E-TTL II for automatic power control.
May control up to 3 different groups (7 combinations).
May be set to one of 7 different channels.
Wireless E-TTL II control from camera position of EX II flash units with a compatible Canon DSLR.
When using EX II flash units, you can also adjust the manual power ratio, FEC and zoom head on remote Speedlites with a compatible Canon DSLR.
Maximum sync. speed is 1/250 second unless using high-speed sync. mode.
High-speed sync., up to 1/8000 second, for EX II flash units connected through the RX hot-shoe.
High-speed sync., up to 1/8000 second, for studio strobes connected through the RX pc-socket.
USB interface for firmware updates. Can also be used for 5 volts DC power supply.
It does not support the Multi stroboscopic mode. For wireless E-TTL II, the flash in the RX hot-shoe must be E-TTL II compatible. Compatible Canon Speedlites are: 580EX II, 430EX II, 320EX, 270EX II. The manual also says that Canon E-TTL II compatible units from third party manufacturers Metz, Sigma, Sunpak and Nissin (no specific models listed) may work.

The TX has very sparse controls. To set it up you use the camera's external flash func. setting-menu. The following Canon EOS bodies are listed as compatible: 450D, 500D, 550D, 600D, 40D, 50D, 60D, 7D, 5D II, 1D III, 1D IV, 1Ds III. Older Canon DSLRs does not let you control the flash from the camera menu, and compatibility is limited to selecting channel and group on TX. It will then “dumb down” and operate like a wireless grouping flash trigger such as the Pixel Bishop.
