No Better Beamer Flash X-tender has been manufactured for the Canon 420EX flash unit. A number of photographers have been able to make the FX-1B unit work but it has not been approved by the manufacturer for that use.

In addition, the manufacturer doesn’t recommend use of a Better Beamer on the Nikon SB-50 due to problems with rigidity.

What Are Ears?

Ears refer to the part of side arms that wrap around the top and bottom of the flash head to help hold it in place. Narrow ears were made to fit flashes that had straight sides while wider ears were made when flashes started to have curved sides.

Replacement Lenses for Better Beamer Flash Extenders

In the event your lens gets scratched, the light output from the flash extender will decrease and the lens should be replaced. The Better Beamer Flash Extender Replacement Lens fits all models.

Always remove and/or cover the Better Beamer Flash Extender lens when it’s not in use.
