Attaching and Detaching the Flash Unit
to the Lens
Be sure to attach the flash unit to the lens when shooting. Shooting while
holding the flash unit in your hand may result in a low temperature burn.
Do not touch the flash unit or batteries immediately after continuous flash
firing or modeling flash (p.34). Touching them may result in a burn. Make
sure that the flash unit has cooled before detaching the flash unit or
replacing batteries.
To rotate the mount ring, be sure to first hold down the release button.
If the Macrolite Adapter 72C screwed onto the EF180mm f/3.5L Macro
USM lens filter thread becomes stuck and cannot be unscrewed, without
pressing the release button, turn the mount ring against the lens in the
direction you would to detach the adapter.
The flash unit cannot be attached to the EF-M28mm f/3.5 Macro IS STM.
When using the following lenses, attach the Macrolite Adapter (sold
separately) to the front of the lens (filter mounting thread) and then attach
the flash unit.
• EF100mm f/2.8L Macro IS USM: Macrolite Adapter 67
• EF180mm f/3.5L Macro USM: Macrolite Adapter 72C
