General Canon Operational Considerations
The following operational considerations apply to all Canon cameras unless otherwise noted.
Calibration Shot
With a Canon camera and ControlTL radios the first exposure after initial connection or power-on is the calibration shot. It is recommended that you take the calibration shot at 1/125. This initiates communication between the camera and radio. This shot will not fire remote flashes.
Manually Select Camera Model
For best results with a Canon camera and ControlTL radios, be sure to manually select your camera model on the transmitting radio. Camera model selection is found on the "Channel" tab.
20D Specific Operational Considerations
The following operational considerations apply only to the 20D.
Camera Firmware
For best results, use the latest camera body firmware. The latest firmware for the 20D is available for download at Canon Firmware Updates.
1/8000th in Automatic Metering modes
The camera’s shutter speed can sometimes get stuck at 1/8000th or f/22 when in P, Av or Tv mode, if a Speedlite is used in the top shoe of an on-camera PocketWizard radio. This can occur with or without PocketWizard radios. This is rare and can be remedied by power-cycling.
Remote Manual Power Control with Local 580EX II
If you use Remote Wireless Manual controls with a 580EX II in the top shoe of a Mini or Flex on a 20D, about 20% of the exposures result in overexposure with remote Speedlites.
HyperSync Performance
Sorry! We don't have any HyperSync results available for this camera yet. To share your own, please contact PocketWizard tech support.
Learn how to configure your radios for best HyperSync performance on our HyperSync Setup page.
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.
