With these Canon cameras, they will not work in TTL mode – sorry! But, you can use the radios in Basic Trigger to fire the remote flash in manual mode, up to X-sync. To enable Basic Trigger mode, connect the radios to the Utility and navigate to the Misc tab. Check the “Basic Trigger” box, then hit Apply Changes. The radios will now work just like the Standard Channel (Plus) radios and use the center pin contact only. You will need to set the flash to manual and make any adjustments on the flash itself.

If you want TTL, you will have to buy just 1 new radio, a Flex TT6 and use it as a transmitter on your camera. Your current TT5s can be used as receivers.

If you have questions on any of this, reach out to our support team at info@pocketwizard.com. We are in Vermont and in the office 8-5 Eastern time. Thanks!
