I am using a flash, the Yongnuo YN-568EXII for Canon, and am facing a zoom issue. It's stuck at 14mm and the M sign is blinking near the zoom button. I am not able to change the zoom. If anyone has any solution please share.


Check that the diffusion panel is fully seated back into its slot. Like the Canon flashes the YN-568EXII is imitating, if the diffusion panel is pulled out, the flash sets itself to the widest zoom and ignores any attempts to set the zoom differently.

  • This is one question where I felt SO should allow us to award extra votes or stars!! After reading this answer the line in page 18 of manual (NOTE: Using wide-angle-diffuser, the flash coverage will then be extended for 14mm. ) makes perfect sense :) – Adarsha Jul 21 '19 at 19:05
