Canon Special Notes
The following special notes apply to all Canon cameras.
In-Camera Speedlite Control
Speedlite controls set via the in-camera menus, like Flash Exposure Compensation and ratio settings, are not currently supported.
Rear-Curtain Sync and Bulb
Rear Curtain Sync and Bulb mode cannot be used together. For more information, visit our Rear Curtain Sync page.
Remote Infrared Control
ControlTL radios disable ALL infra-red/optical communication pulses used in Canon’s native TTL system, and will not trigger remote flashes configured to receive these pulses. A PocketWizard radio is required for each remote flash you want to trigger.
Unsupported Flash Modes
FEB (Flash Exposure Bracketing) and Stroboscopic Flash are not currently supported.
