Optical Transmission Wireless Flash Shooting
Positioning and Operation Range
Using a Canon Speedlite (receiver) with an optical transmission wireless shooting function,
you can easily perform wireless multiple flash shooting in the same way as normal E-TTL II /
E-TTL autoflash strobe photography.
The system is designed so that the settings of the EL-1 (sender unit) are automatically
applied to the EL-1 (receiver unit) controlled wirelessly. Therefore, you do not need to
operate the receiver unit during shooting.
