Why doesn't my Canon Speedlite 420EX Camera Flash fire?
- TThomas OneillJul 25, 2025
The Canon Camera Flash might not fire due to several reasons: * The batteries may be exhausted, so install new batteries. * The batteries may be installed incorrectly; ensure they are in the proper orientation. * The mounting foot might not be securely mounted; slide it all the way into the hot shoe. * The hot shoe contacts may be dirty; clean the contacts.
